- Legacy booleans such as `experimental_use_exec_command_tool`, `experimental_use_unified_exec_tool`, `include_apply_patch_tool`, and similar `experimental_use_*` keys are deprecated; setting the corresponding `[features].<key>` avoids repeated warnings.

Streamable HTTP connections always use the experimental Rust MCP client under the hood, so expect occasional rough edges. OAuth login flows are gated on the `experimental_use_rmcp_client = true` flag:
```toml
experimental_use_rmcp_client = true
```
After enabling it, run `codex mcp login <server-name>` when the server supports OAuth.
Streamable HTTP connections always use the Rust MCP client under the hood. OAuth login
flows are supported by default; run `codex mcp login <server-name>` when the server

When both `enabled_tools` and `disabled_tools` are specified, Codex first restricts the server to the allow-list and then removes any tools that appear in the deny-list.

This flag enables OAuth support for streamable HTTP servers.
