search_openai_docs- Search the OpenAI documentation and return matching page URLs.
As documented on October 17, 2026. A running server reports its current list through tools/list.
Notes and caveats
- Documentation-only and unauthenticated.
- The generic snippet is the documented ~/.codex/config.toml entry.
- Only search_openai_docs appears by name in OpenAI's docs (Responses API example); the docs mention search plus page-content access but do not publish a full tool list.
- OpenAI pairs it with an OpenAI Docs Skill in github.com/openai/skills.
- OpenAI's other former server, Codex as an MCP server (codex mcp-server and the codex-mcp-server binary), has been removed; OpenAI points integrations to the experimental Codex app server, which is not MCP.
