How to Set Up and Use OpenAPI MCP Generator
OpenAPI MCP Generator automatically converts OpenAPI specifications into fully functional MCP servers. This tool bridges REST APIs and AI agents, allowing Claude and other LLMs to interact with any service through auto-generated MCP interfaces with type-safe tool definitions.
Prerequisites
- Node.js 18+ installed
- An MCP client such as Claude Desktop or Cursor
- An OpenAPI 3.0 specification file (YAML or JSON)
Install OpenAPI MCP Generator
Install the generator package via npm.
npx -y openapi-mcp-generatorPrepare your OpenAPI specification
Have your OpenAPI 3.0 spec file ready (local or remote URL).
Generate the MCP server
Run the generator with your OpenAPI spec to create the MCP server. See the repository README for exact command syntax.
openapi-mcp-generator --spec=/path/to/openapi.jsonAdd generated server to client config
Register the generated server in claude_desktop_config.json.
{
"mcpServers": {
"my-api-mcp": {
"command": "node",
"args": ["./generated-server/index.js"]
}
}
}Restart and test
Restart your MCP client and ask Claude to call a tool from your API.

Fetch data from my REST API using the auto-generated toolsTroubleshooting OpenAPI MCP Generator
Generator fails to parse OpenAPI spec
Validate your OpenAPI 3.0 spec using online validators or the Swagger Editor. Ensure the spec is valid YAML or JSON and conforms to OpenAPI 3.0 schema.
Generated server has missing or incorrect tools
Review your OpenAPI specification for completeness. Check the repository README for known limitations and ensure your spec includes proper schemas and descriptions.
