OpenAI Docs MCP Skill
Overview
Use the OpenAI developer documentation MCP server from the shell to search and fetch authoritative docs. Always do this for OpenAI platform work instead of relying on memory or non-official sources.
Core rules
- Always use this skill for OpenAI API/SDK/Apps/Codex questions or when precise, current docs are required.
- Query the MCP server via the CLI wrapper in
scripts/openai-docs-mcp.sh(do not rely on Codex MCP tools). - Use
searchorlistto find the best doc page, thenfetchthe page (or anchor) for exact text. - Surface the doc URL you used in your response so sources are clear.
Quick start
scripts/openai-docs-mcp.sh search "Responses API" 5
scripts/openai-docs-mcp.sh fetch https://platform.openai.com/docs/guides/migrate-to-responsesWorkflow

fetchthe most relevant URL (optionally add an anchor). - Apply: summarize and/or quote relevant sections; include the URL.
