What is the OpenAPI to MCP Converter MCP Server?

OpenAPI to MCP Converter turns an OpenAPI specification into an MCP server instance. The TypeScript library maps documented API operations into tools and proxies their parameters to the underlying API. It is useful when an existing API has a specification but no dedicated MCP integration.

Build from the API definition

Install openapi-mcp-converter and follow the maintainer’s code example to load the OpenAPI document and connect a transport. The README includes stdio and SSE examples. The generated tools depend on the supplied API definition, so there is no universal tool list for this converter.

Check the exposed operations

Inspect the operations and authentication configuration before using the generated server. A specification may include write endpoints as well as reads. Test the intended API operation and returned data in your own environment.

Library setup and examples.

Configuration

Node.js 18 or later. Provide an OpenAPI specification and implement the transport using the documented library example.
