OpenAI Docs

Provide authoritative, current guidance from OpenAI developer docs using the developers.openai.com MCP server. Prioritize MCP doc tools over web search for OpenAI-related questions. Fall back to web search only when MCP returns no meaningful results.

Quick start

• Use mcp__openaiDeveloperDocs__search_openai_docs to find the most relevant doc pages.
• Use mcp__openaiDeveloperDocs__fetch_openai_doc to pull exact sections and quote/paraphrase accurately.
• Use mcp__openaiDeveloperDocs__list_openai_docs only when you need to browse or discover pages without a clear query.
