概览
What is MCP-Compose-Proxy-Shim?
MCP-Compose-Proxy-Shim is a bridge that connects local LLM clients (such as Claude Desktop) to remote MCP-Compose servers running in Docker containers. It intercepts local MCP server calls and redirects them to a remote MCP-Compose proxy, acting as a transparent bridge.
How to use MCP-Compose-Proxy-Shim?
Clone the repository, run npm install, and make scripts executable with chmod +x bin/npx lib/mcp-shim.js. Ensure MCP-Compose is running (mcp-compose up and mcp-compose proxy). Edit Claude Desktop’s configuration file (claude_desktop_config.json) to point to the bin/npx script with your desired MCP server arguments. Set environment variables such as MCP_PROXY_URL (default http://localhost:9876) and MCP_API_KEY before launching Claude Desktop, then restart the client.
Key features of MCP-Compose-Proxy-Shim
- Use Claude Desktop with MCP servers running in Docker containers
- Avoid limitations and costs of paid remote MCP servers
- Leverage all power and flexibility of Docker-based MCP servers
- Works with filesystem, memory, weather and other MCP servers
- Includes security features: path sanitization, rate limiting, API key authentication
- Supports response caching, retry logic, and configurable logging
Use cases of MCP-Compose-Proxy-Shim
- Run containerized filesystem, memory, or weather MCP servers with Claude Desktop
- Use local LLM clients with Docker-based MCP servers without requiring a Claude Max plan
- Combine multiple containerized MCP servers behind a single proxy for a local client
- Securely expose remote MCP servers to desktop clients with authentication and rate limiting
常见问题
How does the shim communicate with MCP-Compose?
The shim talks to Claude via stdin/stdout as expected, then forwards all requests to the MCP-Compose proxy behind the scenes. Results flow back through the proxy to the shim and then to Claude.
What environment variables can I configure?
Key variables include `MCP_PROXY_URL` (proxy address), `MCP_API_KEY`, `MCP_DEBUG`, `MCP_LOG_LEVEL`, `MCP_CACHE`, `MCP_CACHE_TTL_MS`, `MCP_MAX_RETRIES`, and `MCP_LOG_FILE`. Defaults are documented in the README.
Where are logs written?
Logs go to stderr when `MCP_DEBUG=true`, or to a file at `/tmp/mcp-shim-[server].log` when `MCP_LOG_FILE=true`.
What security features are included?
Path sanitization to prevent directory traversal, rate limiting to prevent abuse, request size limiting, API key authentication, and secure error handling.
