- Auto-detects and avoids port conflicts when multiple proxies run.
- Registers all running proxy instances in a home‑directory JSON file.
- Supports overriding HTTP host, port, web page title, and proxy log file.
- Compatible with any STDIO‑based MCP server.
brew tap "emicklei/tap"
and then
brew install emicklei/tap/mcp-log-proxy
or via Go
go install github.com/emicklei/mcp-log-proxy@latest
mcp-log-proxy can be used to see the messages to and from a MCP client and a MCP server using a Web interface.
Currently, it only supports the STDIO interface.
Multiple proxies
All running mcp-log-proxy processes will register themselves in .mcp-log-proxy-instances.json located in your home directory. On the web page, you can use the selector to switch to another proxy instance.
