Overview

What is mcp-one?

mcp-one is a unified all-in-one entrance for MCP servers that manages various types of rated MCP servers. It allows users to run a single server that aggregates multiple MCP tools and resources, then exposes them over SSE to compatible clients like Cherry Studio or Cursor.

How to use mcp-one?

Configure a YAML file listing the MCP servers you want to aggregate, then run ./mcp-one -c mcpone-config.yaml --baseurl 0.0.0.0:9090. Point your MCP client (e.g., Cherry Studio, Cursor) to http://localhost:9090/sse. Pre-built binaries and a Docker image are available; you can also build from source using make build or make dockerbuild.

Frequently asked questions

What does mcp-one actually do?

It runs a single MCP server that embeds and manages multiple other MCP servers, exposing them all through one SSE connection.

Which MCP servers are supported by default?

Currently `time-mcp` and `mcp-server-fetch` are included; you can add any MCP server in the `mcpserver-config.yaml` file.

How do I add a new MCP server to mcp-one?

Edit the YAML configuration file to list the new server’s command, arguments, and environment variables, similar to how you would configure it in a client.

Do I need any runtime besides the binary?

No, the compiled binary includes everything needed. If using Docker, only Docker is required.

How do I expose mcp-one to the internet?

Run it with `--baseurl 0.0.0.0:9090` (or any public address) and ensure the port is reachable. The SSE endpoint will be at `<host>:<port>/sse`.
