What OpenAPI to MCP does

OpenAPI to MCP builds and deploys an MCP server from an OpenAPI or Swagger spec so an LLM can call a REST API. Use it to expose an existing HTTP API as LLM-callable tools with proper schemas and auth.

OpenAPI to MCP is cataloged under AI Engineering on DirSkills. OpenAPI to MCP comes from a repository tagged agent-plugins, agentic-framework, ai, apps-sdk and chatgpt.

Documentation

README

Excerpt

Build an MCP server from an OpenAPI spec

Turn an existing REST API — described by an OpenAPI 3.x or Swagger 2.0 document — into an MCP server. Each operation in the spec becomes one MCP tool the LLM can call. The server runs locally for testing and ships to Manufact / mcp-use cloud with one command.

This skill is the end-to-end recipe: scope → ingest spec → map operations → scaffold → generate tools → wire auth → test → deploy.

Core philosophy: the spec is the contract

The OpenAPI document is the source of truth. Tool names, descriptions, parameter shapes, and auth requirements all come from the spec — they should not be invented. This matters because:
