## What it is
A Python CLI tool that bridges MCP (Model Context Protocol) transports, converting between stdio and SSE/Streamable HTTP. It lets MCP clients like Claude Desktop talk to remote MCP servers whose transport they don't natively support, and vice versa.

## Use cases
- connect Claude Desktop to a remote MCP server over SSE
- expose a local stdio MCP server over HTTP
- proxy MCP requests to a remote server with custom auth headers
- bridge streamable HTTP MCP servers to stdio-only clients
- run MCP servers in Docker and connect them to desktop clients

## When to choose
- you need to connect an MCP client and server that use incompatible transports
- you want to add authentication headers when reaching a remote MCP server
- you need a lightweight, MIT-licensed, pip- or Docker-installable MCP bridge

## When to avoid
- you need a general-purpose HTTP reverse proxy, not an MCP-specific one
- your client and server already share a compatible MCP transport
- you need a GUI-managed MCP gateway with multi-tenant features
