Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.
How agent discovery & health will work →About
Multi MCP
An MCP server that proxies multiple MCP servers.
Getting Started
Clone and cd:
git clone https://github.com/One-MCP/multi-mcp.git
cd multi-mcp
Install dependencies:
uv venv
uv pip install -r requirements.txt
Start server:
hypercorn src.main:app
# hypercorn src.main:app --bind 0.0.0.0:7860
Then you can access the server via http://localhost:8080/sse (for SSE mode) or http://localhost:8080/mcp (for streamable HTTP mode).
Configuration
You can follows the VSCode Documentation#Configuration format to create the configuration JSON files, and there are also example files in the [examples/config](examples/config).
Environment Variables
| Variable Name | Default Value | Description | | --- | --- | --- | | AUTH_TOKEN | None | The authentication token, the server will not perform authentication if not set | | CONFIG | ./examples/config/mcp_tools.json | Path to the MCP configuration file | | ENCODING | utf-8 | The character encoding used for communication | | TRANSPORT | sse | The transport protocol for the server (one of stdio, sse, http) | | USE_NAMESPACE | True | Whether to use namespaces for tools/resources | | DEBUG | False | Enable or disable debug mode |
Authorization Header
This program uses either Authorization or X-MCP-Token HTTP headers for authentication. For the Authorization header, it receives Bearer while for the X-MCP-Token, it receives ``.
Inspiration
This project is inspired by: multi-mcp
