What is 0mcp?

0mcp turns an existing API into a hosted Model Context Protocol server. Start with an OpenAPI 3.x or Swagger 2.0 document, configure REST operations directly, or connect a GraphQL API. Select the operations you want to expose, and 0mcp converts them into tools that compatible AI clients can discover and call.

You do not need to change your API or maintain a separate MCP service. Your API remains responsible for its data, business logic, authentication, and authorization.
