Overview

What is mcp-server-proxy?

mcp-server-proxy is a Go proxy server that converts the MCP (Model Context Protocol) SSE transport layer into standard HTTP request/response patterns. It simplifies MCP server development by allowing developers to handle plain HTTP endpoints without needing to implement SSE details.

How to use mcp-server-proxy?

Install with go install github.com/leizongmin/mcp-server-proxy@latest. Use mcp-server-proxy inspect <local_url> <target_url> to inspect traffic between client and server, or mcp-server-proxy serve <local_url> <target_url> to start a proxy that translates SSE to HTTP.

Key features of mcp-server-proxy

Converts MCP SSE transport to standard HTTP requests/responses
Provides inspect mode to study MCP client-server interactions
Supports initialize, tools/list, and tools/call methods
Allows MCP server implementation in any programming language

Use cases of mcp-server-proxy

Simplify MCP server development without SSE protocol expertise
Research MCP client-server interactions via inspect command
Build MCP servers with any HTTP framework and language
Enable easy MCP client configuration with just a server URL
