OpenAI Docs MCP server tools (5)

As the server lists them. Names and descriptions are the vendor's own.

  • search_openai_docs Search OpenAI Docs
    Read-only

    Search across `platform.openai.com`, `developers.openai.com`, and `learn.chatgpt.com` docs. Use this whenever you are working with the OpenAI API (including the Responses API), OpenAI API SDKs, plugins, ChatGPT, or Codex. Results include URLs—**after `search`, use `fetch_openai_doc`** to read/quote the exact markdown.

  • list_openai_docs List OpenAI Docs
    Read-only

    List or browse pages from `platform.openai.com`, `developers.openai.com`, and `learn.chatgpt.com` that this server crawls (useful when you don’t know the right query yet or you’re paging through results). Use this whenever you are working with the OpenAI API (including the Responses API), OpenAI API SDKs, plugins, ChatGPT, or Codex. Results include URLs—**after `list`, use `fetch_openai_doc`** on a result URL to get the full markdown.

  • fetch_openai_doc Fetch OpenAI Doc
    Read-only

    Fetch the markdown for a specific doc page from `developers.openai.com`, `platform.openai.com`, or `learn.chatgpt.com` so you can quote or summarize exact, up-to-date guidance (schemas, examples, limits, and edge cases). Prefer to **`search_openai_docs` first** (or `list_openai_docs` if you’re browsing) to find the best URL, then `fetch_openai_doc` to pull the exact text; you can pass `anchor` (for example, `#streaming`) to fetch just that section.

  • list_api_endpoints List API Endpoints
    Read-only

    List all OpenAI API endpoint URLs available in the OpenAPI spec.

  • get_openapi_spec Get OpenAPI Spec
    Read-only

    Return the OpenAPI spec for a specific API endpoint URL. Optionally filter code samples by language, or return only code samples.
