An open-source registry of MCP servers, powering your LLMs with external APIs. Create your own MCP server in 10 seconds.
There are more than 100 OpenMCP servers, each in its own directory in ./servers. Each server can be added to your MCP client with a one-liner:
npx @open-mcp/{server_id} add-to-client /path/to/client/config.json
Alternatively you can add the server details to your config manually. See the individual server READMEs for more info.
Adding to the OpenMCP registry is as simple as pasting a link to an OpenAPI specification here:
