Add batched executor capability discovery (#33852)
## Why Selected capability roots can contribute plugins, MCP servers, connectors, and skills. Discovering each contribution separately requires repeated access to the executor filesystem. ## What changed - Add the `capabilityRoots/discoverV1` exec-server RPC to scan selected roots and materialize recognized plugin manifests, configuration files, skill instructions, and skill metadata in one bounded request. - Add the opt-in `executor_capability_discovery` feature, with a thread-scoped cache and per-step snapshot shared by MCP and skill discovery. - Parse MCP, connector, and skill contributions from the materialized snapshot, including serving cached skill instructions without another filesystem read. ## Testing - Cover discovery limits, manifest precedence, root-local failures, cache reuse, plugin contributions, and parity with the existing environment skill loader.

Propagate deferred environment capability roots to MCP (#33427)
## What changed - Let deferred environments provide selected capability roots with their ready signal. - Validate that those roots have unique, non-empty IDs, belong to the registering environment, and stay within the root limit. - Include roots from ready turn environments when resolving MCP contributions, and refresh the MCP runtime when the selected root set changes. - Expose the exact ready root set to MCP contributors so executor plugins become available with their environment. ## Testing - Cover ready-root propagation, validation failures, replacement isolation, reconnection, and MCP plugin availability refresh.

Instrument environment and plugin resolution paths (#33223)
## What changed Add named tracing spans around step environment snapshots, capability and executor plugin resolution, `AGENTS.md` refreshes, and MCP runtime projection and refresh operations. Skip recording function arguments to keep these spans focused on timing and execution flow. GitOrigin-RevId: 73a452ef1b5da6f7f2b00d24421a815c5d514eaf |

Reuse MCP tool catalogs across sessions (#33184)
## Why Starting a new session should not have to wait for an unchanged stdio MCP server to initialize before its tools can be presented to the model. ## What changed - Cache recent tool catalogs for matching stdio MCP server configurations and use them while a new live connection starts in the background. - Bound the process-wide cache to 32 entries with a 30-minute TTL, and key entries by the server configuration, environment, working directory, and elicitation capabilities that affect the catalog. - Keep connection-specific instructions and tool annotations out of cached catalogs. Resolve tool calls against the live connection so tools that are unavailable or hidden in the new session cannot be invoked from stale data. - Publish only the newest completed catalog fetch and do not cache HTTP servers or stdio configurations that depend on remotely sourced environment values. ## Testing - Add coverage for cache expiration, environment changes, catalog sanitization, and out-of-order refreshes. - Add an end-to-end test that starts inference from cached definitions while a replacement MCP process initializes, then verifies calls and visibility against the live process.

Allow injecting the Codex Apps tools cache (#33113)
## What changed - Accept a caller-provided `CodexAppsToolsCache` when constructing a `ThreadManager` and pass it through to the MCP manager. - Add `ConnectorRuntimeManager::new_without_cache()` for an in-memory runtime that neither loads nor persists connector state on disk. - Re-export `CodexAppsToolsCache` from `codex-core` and `codex-core-api` for embedders. ## Testing - Verify that a cache-disabled connector runtime ignores existing disk state and publishes live tools without creating cache files.

Extract connector runtime snapshot management (#32698)
## What changed - Move the Codex Apps tool cache into a reusable `codex-connectors` runtime manager keyed by account and workspace. - Represent cached tools as atomically published snapshots with refresh timestamps while preserving the newest accepted fetch generation. - Harden disk persistence with bounded reads, atomic file replacement, and serialized writes so an older fetch cannot overwrite newer state. ## Testing Add coverage for identity isolation, snapshot timestamps, oversized cache files, atomic replacement, and concurrent persistence ordering.

fix: forward originator to Codex Apps MCP (#31481)
## Summary - Forward Codexs canonical `originator` header on ChatGPT-hosted Apps and plugin-runtime MCP requests. - Preserve the configured `X-OpenAI-Product-Sku` header. - Cover originator-only and originator-plus-SKU configurations. ## Why Sites project creation is logged downstream of Apps MCP. Production validation found `CODEX_UNKNOWN_DEFAULT` project-created threads that matched `codex_surface=desktop_app` and `originator=Codex Desktop` in `fact_codex_cli` ([query](https://kepler.gateway.data-1.internal.api.openai.org/permalink/H_mVoVPqLQ0)). The hosted Apps MCP configuration forwarded the product SKU but not Codexs canonical originator, so codex-backend could not derive `CODEX_DESKTOP_APP` for those tool calls. ## Validation - `just fmt` - `CARGO_HOME=/private/tmp/codex-cargo-home CARGO_TARGET_DIR=/private/tmp/codex-target just test -p codex-mcp` (106 passed) - `CARGO_HOME=/private/tmp/codex-cargo-home CARGO_TARGET_DIR=/private/tmp/codex-target just fix -p codex-mcp` |

Make plugin guidance react to environment readiness (#30223)
## Why Generic plugin guidance is currently emitted only with initial context from host plugin state. An executor-selected plugin can become available later in the same turn, making its skills and tools usable without ever telling the model how plugin capabilities should be used. ## What - project every ready selected plugin package, including skill-only plugins - carry plugin availability with the exact MCP runtime projection while preserving MCP manager reuse when servers and connectors are unchanged - move generic plugin guidance from the static initial-context path into persisted World State - recognize legacy and retained plugin fragments so resume and compaction do not duplicate guidance ## Testing - `just test -p codex-mcp-extension` - `just test -p codex-core plugins_instructions` - `just test -p codex-core plugin_availability_change_reuses_the_mcp_manager` - `just test -p codex-app-server --test all selected_capabilit` |

Project selected plugin runtime by environment availability (#30093)
## Why
Selected plugin metadata is stable, but MCP processes are live runtime
state. They need different lifetimes:
- the MCP extension caches manifest, MCP, and connector declarations for
each stable selected root;
- each model step projects that cached metadata through the roots that
resolved as ready for that exact step;
- the MCP manager is rebuilt only when that availability projection
changes.
This matches executor skills: both features consume the same resolved
step roots instead of inferring readiness from the turn's selected
environments.
## Behavior
```text
E1 not ready for this step
-> no E1 MCP servers or connectors
-> cached plugin metadata stays in ext/mcp
E1 becomes ready
-> reuse cached metadata
-> publish one MCP runtime containing E1 capabilities
same ready roots on the next step
-> reuse the exact runtime; no rediscovery and no MCP restart
resume
-> create new extension thread state and a new MCP runtime
```
All model-facing consumers use the same step snapshot:
```text
resolved selected roots
|
v
extension MCP/connector projection
|
v
{ MCP config, connector snapshot, MCP manager }
|
+-> advertise model tools
+-> build app/connector tools
+-> execute MCP calls
```
## Cache contract
The existing MCP extension owns a cache keyed by the full
`SelectedCapabilityRoot`:
```rust
let state = thread_store.get_or_init(SelectedExecutorPluginMcpState::default);
```
The cache lives with extension thread state. Environment availability
filters projection but does not invalidate metadata. Resume creates new
thread state. There is no file watcher or executor generation because
contents behind a stable environment/root are assumed stable.
## What changes
- Keeps executor plugin discovery and cached metadata in `ext/mcp`.
- Caches MCP and connector declarations together per selected root.
- Uses the step's already-resolved capability roots, including lazy
environments that are not turn environments.
- Reuses the current MCP runtime when the ready-root projection is
unchanged.
- Uses the same step MCP manager and connector snapshot for
model-visible tools and execution.
- Resolves direct thread-scoped MCP requests from the current
selected-root projection.
## Deliberately out of scope
- `app/list` remains based on the latest global host-plugin state; this
PR does not make its response or notifications thread-specific.
- `required = true` startup semantics do not apply to delayed executor
MCP activation.
- No filesystem/content invalidation.
- No transport-disconnect watcher.
- No executor generations or environment replacement semantics.
- No client sharing across complete manager replacements.
## Stack
1. Extension-owned World State sections.
2. Project executor skills through World State.
3. Pin one MCP runtime to each model step.
4. **This PR:** project selected MCP and connector state from
extension-owned metadata.
5. Integration coverage for selected capability availability and resume.
## Verification
-
`selected_plugin_servers_use_managed_requirements_for_the_selected_root_id`
- The stacked integration PR covers unavailable to ready activation,
unchanged-runtime reuse, skills, MCP tools, connector attribution, and
cold resume.

feat(core, mcp): cache codex_apps tools in memory (#29003)
## Description This makes Codex Apps tool reads use a shared in-memory snapshot instead of rereading the disk cache every time `list_all_tools()` runs. Disk still seeds the cache on startup and gets updated after successful fetches, but it is no longer the live read path. The core change is that `McpManager` now owns a process-scoped `CodexAppsToolsCache`. Codex threads in the same app-server process now share this Codex Apps in-memory tools snapshot. The snapshot is keyed by the Codex home plus the Codex Apps identity: the active Codex auth user/workspace and the effective Codex Apps MCP source config. There's already code to hard-refresh the cache, so we respect it in this PR. ## Local benchmark I ran a local steady-state microbenchmark of the exact repeated Codex Apps cached-tools read this PR removes, using the same real local cache payload in both trees: `3,678,138` bytes and `381` tools. The cache file was already warm in the OS page cache, so this measures same-process reread/deserialization work rather than cold-disk latency or full turn latency. Each run is 25 iterations (mimicking a turn that makes 25 inference calls). | Version | Run 1 | Run 2 | Avg | |---|---:|---:|---:| | `origin/main` disk read + JSON deserialize + `filter_tools` | `50.755 ms` | `52.894 ms` | `51.825 ms` | | This branch in-memory `current_tools` + `filter_tools` | `0.740 ms` | `0.778 ms` | `0.759 ms` | That removes about `51 ms` from each repeated Codex Apps cached-tools read on this machine, roughly `68x` faster for that subpath. It is useful evidence for the hot path this PR changes, but not a claim that every production turn gets `51 ms` faster; end-to-end impact also depends on the rest of `list_all_tools()` and tool-payload construction. This is on my M2 Max macbook, so with a slower disk this would be much worse (and indeed we did see this really blew up turn runtime with a slow disk). |

Add selected-plugin precedence and attribution to the MCP catalog (#27884)
## Why **In short:** this PR resolves already-discovered MCP registrations. It does not read selected plugins or discover their MCP servers. The resolved MCP catalog currently builds config and auto-discovered plugin registrations before runtime contributors are applied. A thread-selected plugin needs a distinct precedence tier in that same initial resolution pass: otherwise a disabled lower-precedence winner can leave stale name-level state behind, and the winning MCP tools cannot be attributed to the selected package reliably. This PR adds that catalog boundary before executor discovery is connected. ## What changed - Added an explicit selected-plugin registration tier between auto-discovered plugins and explicit config. - Collected selected-plugin contributions before the initial catalog build, while leaving compatibility and generic extension overlays in their existing runtime phase. - Retained the winning plugin ID and display name directly on plugin-owned catalog registrations. - Derived MCP tool provenance from the winning catalog entry instead of joining against local-only plugin summaries. - Retained the winning selected server's tool approval policy in the running connection manager, so a selected registration cannot inherit approval behavior from a losing local plugin. - Kept remembered approval session-scoped for selected plugins until there is an authority-aware persistence contract; Codex will not write approval back to an unrelated local plugin. - Preserved existing name-level disabled vetoes for discovered plugins and config, while keeping a selected package's own disabled registration scoped to that registration. - Preserved deterministic selection order and existing config, compatibility, and extension precedence. The resulting order is: ```text auto-discovered plugin < selected plugin < explicit config < compatibility registration < extension overlay ``` ## Behavior and scope This is a catalog and provenance change only. No production host contributes selected-plugin MCP registrations yet, so existing local MCP behavior remains unchanged. The stacked follow-up, #27870, installs the executor plugin provider that produces these registrations. App-server activation remains a separate final step. ## Verification Focused tests cover precedence, deterministic selected-plugin conflicts, disabled-veto behavior across catalog phases, managed requirements before selected-plugin resolution, winning-server approval policy, and attribution when local and selected packages share an ID or server name. CI owns execution of the test suite. |

Make MCP server contributions thread-scoped (#27670)
## Why `selectedCapabilityRoots` belongs to one thread, but MCP contributors previously received only the global Codex config. That left no clean way for a selected executor capability to contribute MCP servers to its own thread. ## What this PR does - Gives MCP contributors a small context containing the config and, for a running thread, its frozen host-seeded inputs. - Uses the same thread inputs during startup, status queries, refreshes, and skill dependency checks. - Keeps threadless MCP operations and the existing hosted Apps behavior unchanged. - Adds coverage showing that two threads resolve independent registrations and that later lifecycle mutations do not change the frozen MCP inputs. This PR does not discover plugin manifests, add MCP servers, or launch anything new. It only establishes the thread-scoped registration boundary. ## Follow-ups - Resolve selected executor plugin roots through their owning environment filesystem. - Convert their stdio MCP declarations into environment-bound registrations and add an executor MCP end-to-end test. ## Verification - `just fmt` - `cargo check --tests -p codex-protocol -p codex-extension-api -p codex-mcp-extension -p codex-core -p codex-app-server` Tests and Clippy were not run. |

Resolve MCP server registrations through a catalog (#27634)
## Why MCP servers currently come from user config, local plugins, compatibility Apps synthesis, and host extensions. Those sources were composed by mutating a shared map, leaving registration identity, precedence, removal, and provenance implicit in assembly order. Before adding executor-owned MCPs, Codex needs one durable resolution boundary above `McpConnectionManager`. This PR introduces that boundary while preserving current server configuration, policy, and runtime behavior. Executor-scoped registrations and explicit policy layers remain follow-ups. ## What changed - Add typed `McpServerRegistration` inputs and an immutable `ResolvedMcpCatalog` in `codex-mcp`. - Retain each registration's complete `McpServerConfig`, including its environment binding, while recording its source and provenance. - Preserve the existing structural precedence between plugin, config, compatibility, and ordered extension sources. - Resolve equal-precedence actions by contribution order; provenance IDs are used only for diagnostics and cannot affect the winner. - Preserve extension removals and the existing name-scoped `enabled = false` veto. - Report same-tier conflicts with every contender and the final catalog outcome, including whether the winning action registers or removes the server. - Require MCP contributors to provide a stable diagnostic identity. - Derive materialized server maps and plugin ownership from the resolved catalog. `McpConnectionManager`, transport startup, tool calls, and resource routing continue to consume the same effective `McpServerConfig` values. ## Scope This PR does not add new MCP capabilities or change user-visible behavior. It does not add executor plugin discovery, thread-scoped registrations, dynamic refresh generations, or new user/managed policy semantics. ## Verification - Added focused catalog coverage for source precedence, complete configuration preservation, disabled vetoes, plugin ownership, contribution-order tie breaking, removal outcomes, and conflict diagnostics. - Extended hosted Apps coverage for ordered extension removal and Apps-disabled hosts with and without the hosted extension installed. - `cargo check -p codex-mcp --tests -p codex-extension-api -p codex-core` |

[codex] Preserve disabled MCP servers across runtime overlays (#27414)
## Why Recent MCP runtime overlay changes replace same-name configured server entries with compatibility or extension-provided configs. Those replacement configs default to enabled, so an MCP server explicitly configured with `enabled = false` could be initialized anyway. The connection manager still filters disabled servers correctly, but the configured disabled state was lost before initialization reached that filter. ## What changed - Remember MCP servers that are disabled in the configured view before applying runtime fallbacks and extension overlays. - Restore `enabled = false` for those servers after overlays, while leaving all other overlay fields and `Remove` precedence unchanged. - Add focused extension-backed regression coverage for a disabled `codex_apps` server. ## Testing - `just fmt` - `just test -p codex-mcp-extension` - `just fix -p codex-core` - `just fix -p codex-mcp-extension` The full workspace `just test` suite was not run. |

Use plugin-service MCP as the hosted plugin runtime (#27198)
## Stack - Base: #27191 - This PR is the third vertical and should be reviewed against `jif/external-plugins-2`, not `main`. ## Why #27191 moves the host-owned Apps MCP registration behind an extension contributor, but deliberately preserves the existing endpoint-selection feature while that contribution contract lands. App-server can therefore resolve the server through extensions, yet the hosted plugin endpoint is still selected through temporary `apps_mcp_path_override` plumbing. That is not the long-term plugin model. A plugin can bundle skills, connectors, MCP servers, and hooks, and those components do not all need the same source or execution environment. In particular, an authenticated HTTP MCP server can expose plugin capabilities directly from a backend without an executor or an orchestrator filesystem. This PR completes that hosted vertical. App-server's MCP extension now owns the aggregate hosted plugin runtime at `/ps/mcp`. Connector actions continue to arrive as MCP tools, while backend-provided skills arrive as MCP resources and use Codex's existing resource list/read paths. No second backend client, skill filesystem, or generic plugin activation framework is introduced. The backend route remains the hosted implementation. This change replaces Codex's temporary endpoint-selection mechanism, not the service behind the endpoint. ## What changed ### Hosted plugin runtime The MCP extension now contributes `codex_apps` as the hosted plugin runtime rather than as a configurable Apps endpoint: - `https://chatgpt.com` resolves to `https://chatgpt.com/backend-api/ps/mcp`; - a bare custom ChatGPT base resolves to `/api/codex/ps/mcp`; - the existing product-SKU header and ChatGPT authentication behavior are preserved; - executor availability is never consulted for this streamable HTTP transport. The same MCP connection carries both component shapes supported by the hosted endpoint: - connector actions are discovered and invoked as MCP tools; - hosted skills are enumerated and read as MCP resources through the existing `list_mcp_resources` and `read_mcp_resource` paths. This keeps component access in the subsystem that already owns the protocol instead of downloading backend skills into an orchestrator filesystem or inventing a parallel hosted-skill client. ### Explicit runtime ordering `McpManager` now resolves the reserved `codex_apps` entry in three ordered phases: 1. install the legacy Apps fallback for compatibility; 2. apply ordered extension `Set` or `Remove` overlays; 3. apply the final ChatGPT-auth gate without synthesizing the server again. This ordering is important: - an ordinary configured or plugin MCP server cannot claim the auth-bearing `codex_apps` name; - an extension-contributed hosted runtime wins over the fallback; - an extension `Remove` remains authoritative; - a host without the MCP extension retains the legacy Apps endpoint and current local-only behavior. The temporary `legacy_apps_mcp_loader_enabled` coordination flag is no longer needed. ### Remove the path override The `apps_mcp_path_override` feature and its runtime plumbing are removed, including: - the feature registry entry and structured feature config; - `Config` and `McpConfig` fields; - config schema output; - config-lock materialization; - URL override handling in `codex-mcp`. Existing boolean and structured forms still deserialize as ignored compatibility input. They are omitted from new serialized config, and config-lock comparison normalizes the removed input so older locks remain replayable. ### App-server coverage App-server MCP fixtures now serve the hosted route at `/api/codex/ps/mcp`. Existing resource-read and tool/elicitation flows therefore exercise the extension-owned endpoint rather than succeeding through the legacy fallback. The stack also adds the missing `codex_chatgpt::connectors` re-export for the manager-backed connector helper introduced in #27191. ## Compatibility - App-server installs the extension and uses `/ps/mcp` for the hosted runtime. - CLI and other hosts that do not install the extension retain the legacy Apps endpoint. - Apps disabled or non-ChatGPT authentication removes `codex_apps` from the effective runtime view. - Existing local plugins, local skills, executor-selected skills, configured MCP servers, and MCP OAuth behavior are otherwise unchanged. - Backend plugin enablement remains account/workspace state owned by the hosted endpoint; this PR does not add thread-local backend plugin selection. ## Architectural fit The stack now proves two independent runtime shapes: 1. #27184 resolves filesystem-backed skills through the executor that owns a selected root. 2. #27191 and this PR resolve a backend-hosted HTTP MCP through an extension with no executor. Together they preserve the intended separation: - selection identifies a plugin/root when explicit selection is needed; - each component's owning extension resolves its concrete access mechanism; - execution stays with the runtime required by that component; - existing skills, MCP, connector, and hook subsystems remain the downstream consumers. ## Planned follow-ups 1. **Executor stdio MCP:** selecting an executor plugin registers a manifest-declared stdio MCP server and executes it in the environment that owns the plugin. 2. **Optional backend selection:** only if CCA needs thread-local selection distinct from backend account/workspace enablement, add a concrete backend-owned capability location and surface those selected skills through the skills catalog. 3. **Connector metadata and hooks:** activate those plugin components through their existing owning subsystems, with executor hooks remaining environment-bound. 4. **Propagation and persistence:** define explicit resume, fork, subagent, refresh, and environment-removal semantics once selected roots have multiple real consumers. 5. **Local convergence:** migrate legacy local skill, MCP, connector, and hook paths behind their owning extensions one vertical at a time, then remove duplicate core managers and compatibility plumbing after parity. ## Verification Coverage in this change exercises: - extension-owned `/backend-api/ps/mcp` registration without an executor; - preservation of the legacy endpoint in hosts without the extension; - extension `Set` and `Remove` precedence over the legacy fallback; - ChatGPT-auth gating for the reserved server; - hosted MCP resource reads with and without an active thread; - connector tool invocation and MCP elicitation through the hosted route; - ignored boolean and structured forms of the removed path override; - config-lock replay compatibility for the removed feature. `cargo check -p codex-features -p codex-mcp-extension -p codex-app-server` passes. Tests and Clippy were not run locally under the current development instruction; CI provides the full validation pass. |

Route hosted Apps MCP through extensions (#27191)
## Stack - Base: #27184 - This PR is the second vertical and should be reviewed against `jif/external-plugins-1`, not `main`. ## Why CCA is moving toward a split runtime where the orchestrator may have no filesystem or executor, but it still needs to activate remotely hosted plugin components. HTTP MCP servers are the simplest complete example: they need configuration and host authentication, but they do not need an executor process. The Apps MCP endpoint is currently synthesized by a special-purpose loader inside the MCP runtime. That works locally, but it leaves hosted MCP activation outside the extension model being established in #27184. It also makes the Apps path a poor foundation for plugins whose skills, MCP servers, connectors, and hooks may come from different sources or execute in different places. This PR moves that one behavior behind an extension-owned contribution while preserving the existing local fallback. It deliberately does not introduce a generic plugin activation framework. ## What changed ### MCP extension contribution `codex-extension-api` gains an ordered `McpServerContributor` contract. A contributor returns typed `Set` or `Remove` overlays for MCP server configuration; later contributors win for the names they own. The contract stays at the existing MCP configuration boundary. Extensions do not create a second connection manager or transport abstraction. ### Hosted Apps MCP extension A new `codex-mcp-extension` contributes the reserved `codex_apps` server from the existing Apps feature, ChatGPT base URL, path override, and product SKU configuration. When `apps_mcp_path_override` is enabled for `https://chatgpt.com`, the resulting streamable HTTP endpoint is `https://chatgpt.com/backend-api/ps/mcp`. The existing ChatGPT-auth gate remains authoritative, so this server can run in an orchestrator-only process without being exposed for API-key sessions. ### One resolved runtime view `McpManager` now distinguishes three views: - **configured:** config- and plugin-backed servers before extension overlays; - **runtime:** configured servers plus host-installed extension contributions; - **effective:** runtime servers after auth gating and compatibility built-ins. App-server installs the hosted MCP extension and uses the runtime view for thread startup, refresh, status, threadless resource reads, connector discovery, and MCP OAuth lookup. This keeps `mcpServer/oauth/login` consistent with the servers exposed by the other MCP APIs. The hosted Apps server itself continues to use existing ChatGPT host authentication rather than MCP OAuth. ## Compatibility Hosts that do not install the MCP extension retain the existing Apps MCP synthesis path. This preserves current local-only, CLI, and standalone-host behavior while app-server exercises the extension path. Disabling Apps removes the reserved `codex_apps` entry, and losing ChatGPT auth removes it from the effective runtime view. Executor availability is not consulted for this HTTP transport. ## Follow-ups The next vertical will resolve a manifest-declared stdio MCP server from an executor-selected plugin root and execute it in the environment that owns that root. Later verticals can add backend-owned skills, connector metadata, hooks, durable selection semantics, and incremental local convergence without changing the component-specific runtime boundaries introduced here. ## Verification Focused coverage was added for: - contributing the hosted Apps MCP at `/backend-api/ps/mcp` without an executor; - requiring ChatGPT auth in the effective runtime view; - removing a reserved configured Apps server when the Apps feature is disabled. `cargo check -p codex-app-server -p codex-mcp-extension -p codex-extension-api -p codex-mcp` passed. Tests and Clippy were not run locally under the current development instruction; CI provides the full validation pass. |

feat: make built-in MCPs first-class runtime servers (#21356)
## DISCLAIMER This is experimental and no production service must rely on this ## Why Built-in MCPs are product-owned runtime capabilities, but they were previously flattened into the same config-backed stdio path as user-configured servers. That made them depend on a hidden `codex builtin-mcp` re-exec path, exposed them through config-oriented CLI flows, and erased distinctions the runtime needs to preserve—most notably whether an MCP call should count as external context for memory-mode pollution. ## What changed - Model product-owned built-ins separately from config-backed MCP servers via `BuiltinMcpServer` and `EffectiveMcpServer`. - Launch built-ins in process through a reusable async transport instead of the hidden `builtin-mcp` stdio subcommand. - Keep config-oriented CLI operations such as `codex mcp list/get/login/logout` scoped to configured servers, while merging built-ins only into the effective runtime server set. - Retain server metadata after launch so parallel-tool support and context classification come from the live server set; built-in `memories` is now classified as local Codex state rather than external context. ## Test plan - `cargo test -p codex-mcp` - `cargo test -p codex-core --test suite builtin_memories_mcp_call_does_not_mark_thread_memory_mode_polluted_when_configured` --------- Co-authored-by: Codex <noreply@openai.com> |

fix: fully revert agent identity runtime wiring (#18757)
## Summary This PR fully reverts the previously merged Agent Identity runtime integration from the old stack: https://github.com/openai/codex/pull/17387/changes It removes the Codex-side task lifecycle wiring, rollout/session persistence, feature flag plumbing, lazy `auth.json` mutation, background task auth paths, and request callsite changes introduced by that stack. This leaves the repo in a clean pre-AgentIdentity integration state so the follow-up PRs can reintroduce the pieces in smaller reviewable layers. ## Stack 1. This PR: full revert 2. https://github.com/openai/codex/pull/18871: move Agent Identity business logic into a crate 3. https://github.com/openai/codex/pull/18785: add explicit AgentIdentity auth mode and startup task allocation 4. https://github.com/openai/codex/pull/18811: migrate auth callsites through AuthProvider ## Testing Tests: targeted Rust checks, cargo-shear, Bazel lock check, and CI. |

[codex] Use background agent task auth for backend calls (#18094)
## Summary Introduces a single background/control-plane agent task for ChatGPT backend requests that do not have a thread-scoped task, with `AuthManager` owning the default ChatGPT backend authorization decision. Callers now ask `AuthManager` for the default ChatGPT backend authorization header. `AuthManager` decides whether that is bearer or background AgentAssertion based on config/internal state, while low-level bootstrap paths can explicitly request bearer-only auth. This PR is stacked on PR4 and focuses on the shared background task auth plumbing plus the first tranche of backend/control-plane consumers. The remaining callsite wiring is split into PR4.2 to keep review size down. ## Stack - PR1: https://github.com/openai/codex/pull/17385 - add `features.use_agent_identity` - PR2: https://github.com/openai/codex/pull/17386 - register agent identities when enabled - PR3: https://github.com/openai/codex/pull/17387 - register agent tasks when enabled - PR3.1: https://github.com/openai/codex/pull/17978 - persist and prewarm registered tasks per thread - PR4: https://github.com/openai/codex/pull/17980 - use task-scoped `AgentAssertion` for downstream calls - PR4.1: this PR - introduce AuthManager-owned background/control-plane `AgentAssertion` auth - PR4.2: https://github.com/openai/codex/pull/18260 - use background task auth for additional backend/control-plane calls ## What Changed - add background task registration and assertion minting inside `codex-login` - persist `agent_identity.background_task_id` separately from per-session task state - make `BackgroundAgentTaskManager` private to `codex-login`; call sites do not instantiate or pass it around - teach `AuthManager` the ChatGPT backend base URL and feature-derived background auth mode from resolved config - expose bearer-only helpers for bootstrap/registration/refresh-style paths that must not use AgentAssertion - wire `AuthManager` default ChatGPT authorization through app listing, connector directory listing, remote plugins, MCP status/listing, analytics, and core-skills remote calls - preserve bearer fallback when the feature is disabled, the backend host is unsupported, or background task registration is not available ## Validation - `just fmt` - `cargo check -p codex-core -p codex-login -p codex-analytics -p codex-app-server -p codex-cloud-requirements -p codex-cloud-tasks -p codex-models-manager -p codex-chatgpt -p codex-model-provider -p codex-mcp -p codex-core-skills` - `cargo test -p codex-login agent_identity` - `cargo test -p codex-model-provider bearer_auth_provider` - `cargo test -p codex-core agent_assertion` - `cargo test -p codex-app-server remote_control` - `cargo test -p codex-cloud-requirements fetch_cloud_requirements` - `cargo test -p codex-models-manager manager::tests` - `cargo test -p codex-chatgpt` - `cargo test -p codex-cloud-tasks` - `just fix -p codex-core -p codex-login -p codex-analytics -p codex-app-server -p codex-cloud-requirements -p codex-cloud-tasks -p codex-models-manager -p codex-chatgpt -p codex-model-provider -p codex-mcp -p codex-core-skills` - `just fix -p codex-app-server` - `git diff --check` |

[codex] reduce module visibility (#16978)
## Summary - reduce public module visibility across Rust crates, preferring private or crate-private modules with explicit crate-root public exports - update external call sites and tests to use the intended public crate APIs instead of reaching through module trees - add the module visibility guideline to AGENTS.md ## Validation - `cargo check --workspace --all-targets --message-format=short` passed before the final fix/format pass - `just fix` completed successfully - `just fmt` completed successfully - `git diff --check` passed |

core: remove cross-crate re-exports from lib.rs (#16512)
## Why `codex-core` was re-exporting APIs owned by sibling `codex-*` crates, which made downstream crates depend on `codex-core` as a proxy module instead of the actual owner crate. Removing those forwards makes crate boundaries explicit and lets leaf crates drop unnecessary `codex-core` dependencies. In this PR, this reduces the dependency on `codex-core` to `codex-login` in the following files: ``` codex-rs/backend-client/Cargo.toml codex-rs/mcp-server/tests/common/Cargo.toml ``` ## What - Remove `codex-rs/core/src/lib.rs` re-exports for symbols owned by `codex-login`, `codex-mcp`, `codex-rollout`, `codex-analytics`, `codex-protocol`, `codex-shell-command`, `codex-sandboxing`, `codex-tools`, and `codex-utils-path`. - Delete the `default_client` forwarding shim in `codex-rs/core`. - Update in-crate and downstream callsites to import directly from the owning `codex-*` crate. - Add direct Cargo dependencies where callsites now target the owner crate, and remove `codex-core` from `codex-rs/backend-client`. |

core: use codex-mcp APIs directly (#16510)
## Why `codex-mcp` already owns the shared MCP API surface, including `auth`, `McpConfig`, `CODEX_APPS_MCP_SERVER_NAME`, and tool-name helpers in [`codex-rs/codex-mcp/src/mcp/mod.rs`](https://github.com/openai/codex/blob/f61e85dbfb5373cde6827d232ac8ea447c237e81/codex-rs/codex-mcp/src/mcp/mod.rs#L1-L35). Re-exporting that surface from `codex_core::mcp` gives downstream crates two import paths for the same API and hides the real crate dependency. This PR keeps `codex_core::mcp` focused on the local `McpManager` wrapper in [`codex-rs/core/src/mcp.rs`](https://github.com/openai/codex/blob/f61e85dbfb5373cde6827d232ac8ea447c237e81/codex-rs/core/src/mcp.rs#L13-L40) and makes consumers import shared MCP APIs from `codex_mcp` directly. ## What - Remove the `codex_mcp::mcp` re-export surface from `core/src/mcp.rs`. - Update `codex-core` internals plus `codex-app-server`, `codex-cli`, and `codex-tui` test code to import MCP APIs from `codex_mcp::mcp` directly. - Add explicit `codex-mcp` dependencies where those crates now use that API surface, and refresh `Cargo.lock`. ## Verification - `just bazel-lock-check` - `cargo test -p codex-core -p codex-cli -p codex-tui` - `codex-cli` passed. - `codex-core` still fails five unrelated config tests in `core/src/config/config_tests.rs` (`approvals_reviewer_*` and `smart_approvals_alias_*`). - A broader `cargo test -p codex-core -p codex-app-server -p codex-cli -p codex-tui` run previously hung in `codex-app-server` test `in_process_start_uses_requested_session_source_for_thread_start`. |

Extract MCP into codex-mcp crate (#15919)
- Split MCP runtime/server code out of `codex-core` into the new `codex-mcp` crate. New/moved public structs/types include `McpConfig`, `McpConnectionManager`, `ToolInfo`, `ToolPluginProvenance`, `CodexAppsToolsCacheKey`, and the `McpManager` API (`codex_mcp::mcp::McpManager` plus the `codex_core::mcp::McpManager` wrapper/shim). New/moved functions include `with_codex_apps_mcp`, `configured_mcp_servers`, `effective_mcp_servers`, `collect_mcp_snapshot`, `collect_mcp_snapshot_from_manager`, `qualified_mcp_tool_name_prefix`, and the MCP auth/skill-dependency helpers. Why: this creates a focused MCP crate boundary and shrinks `codex-core` without forcing every consumer to migrate in the same PR. - Move MCP server config schema and persistence into `codex-config`. New/moved structs/enums include `AppToolApproval`, `McpServerToolConfig`, `McpServerConfig`, `RawMcpServerConfig`, `McpServerTransportConfig`, `McpServerDisabledReason`, and `codex_config::ConfigEditsBuilder`. New/moved functions include `load_global_mcp_servers` and `ConfigEditsBuilder::replace_mcp_servers`/`apply`. Why: MCP TOML parsing/editing is config ownership, and this keeps config validation/round-tripping (including per-tool approval overrides and inline bearer-token rejection) in the config crate instead of `codex-core`. - Rewire `codex-core`, app-server, and plugin call sites onto the new crates. Updated `Config::to_mcp_config(&self, plugins_manager)`, `codex-rs/core/src/mcp.rs`, `codex-rs/core/src/connectors.rs`, `codex-rs/core/src/codex.rs`, `CodexMessageProcessor::list_mcp_server_status_task`, and `utils/plugins/src/mcp_connector.rs` to build/pass the new MCP config/runtime types. Why: plugin-provided MCP servers still merge with user-configured servers, and runtime auth (`CodexAuth`) is threaded into `with_codex_apps_mcp` / `collect_mcp_snapshot` explicitly so `McpConfig` stays config-only. |
