Names and descriptions come from the vendor's server. - `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` (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` (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` (read-only): List all OpenAI API endpoint URLs available in the 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. ### Connect it Claude Code: ```sh claude mcp add --transport http openai https://developers.openai.com/mcp ``` - Add to Cursor: - Add to VS Code: - Claude.ai and Claude Desktop: Customize, Connectors, "+", Add custom connector, then paste https://developers.openai.com/mcp - ChatGPT: Settings, Apps, Advanced settings, turn on Developer mode, Create, then paste https://developers.openai.com/mcp JSON for Cursor, Windsurf and other clients that connect to hosted servers: ```json { "mcpServers": { "openai": { "type": "http", "url": "https://developers.openai.com/mcp" } } } ``` ## Questions ### Does OpenAI have an official MCP server?
