What this skill does

Build and deploy an MCP server from an OpenAPI / Swagger spec using the mcp-use TypeScript SDK. Use this skill whenever the user wants to "turn this OpenAPI spec into an MCP server", "make this API usable from Claude/ChatGPT", "wrap this Swagger doc as MCP tools", "expose this REST API to an LLM", "generate MCP tools from a spec", or pastes/attaches an openapi.yaml, openapi.json, or swagger.json and asks for a Claude-compatible version.

When it triggers

  • Trigger even if the user doesn't say "MCP" — if they describe an existing HTTP API (REST endpoints, an internal service, a third-party API they have a key for) and want an LLM to call it, this is the right skill.
  • "turn this OpenAPI spec into an MCP server"
  • "make this API usable from Claude/ChatGPT"
  • "wrap this Swagger doc as MCP tools"
  • "expose this REST API to an LLM"
  • "generate MCP tools from a spec"
  • "MCP"
