OpenAPI to MCP: converter, generator, MCP server from OpenAPI

OpenAPI to MCP converter and generator

If you’re looking for an OpenAPI to MCP converter or generator, Api2Agent does exactly that: you provide your OpenAPI spec (JSON or YAML), and we generate a ready-to-run MCP server that exposes your API as MCP tools. No hand-coding of tool schemas or server scaffolding—you get a downloadable TypeScript project.

What you get

• MCP server from OpenAPI — one tool per API operation (or a curated subset).
• TypeScript MCP server — standard MCP server implementation you can run locally or deploy.
• MCP server scaffold from OpenAPI — tool handlers, config, README, and .env.example so you can extend or customize.
• OpenAPI to MCP tools — parameters and descriptions derived from your spec.

Generate MCP server from OpenAPI spec

The workflow is simple: upload or paste your OpenAPI document, choose any options (e.g. which operations to expose), then download a ZIP. The ZIP contains the MCP server project. Install deps, set env vars (e.g. base URL, API key), and run it. You can then point Cursor, Claude Desktop, or another MCP client at this server so agents can call your API.

OpenAPI to MCP server scaffold

We generate a scaffold, not a hosted service. Download and run locally — we don't host; you get a project to run or deploy yourself. You own the code, run it locally or on your own infrastructure, and we don’t host or store your spec long-term.

API to MCP converter

If your API is described by OpenAPI (or you can export OpenAPI from your API), the same flow applies: paste or upload the spec and get an MCP server that acts as an API-to-MCP converter. The server translates MCP tool calls into HTTP requests to your API.

Use the OpenAPI to MCP generator on the homepage — paste your spec and download the scaffold.
