### Description (declared)

# mcp-streamablehttp-proxy

A generic stdio-to-StreamableHTTP bridge for MCP (Model Context Protocol) servers. This proxy enables any stdio-based MCP server to be accessed via HTTP endpoints, making them compatible with web-based clients and HTTP infrastructure like API gateways.

## Overview

The `mcp-streamablehttp-proxy` acts as a translation layer between:
- **MCP clients** that speak StreamableHTTP (like Claude.ai, web-based IDEs)
- **MCP servers** that only speak stdio JSON-RPC (like the official MCP servers)

It manages sessions, spawns server subprocesses, and handles the protocol translation transparently.

## Features

- **Universal MCP Server Support** - Works with any stdio-based MCP server
- **Session Management** - Each client gets an isolated server subprocess
- **Full Protocol Support** - Handles the complete MCP lifecycle
- **Configurable** - Flexible timeout, host, and port configuration
- **Production Ready** - Async implementation with proper cleanup
- **Gateway Compatible** - Designed for use with Traefik and OAuth gateways

## Installation

### Via pip
```bash
pip install mcp-streamablehttp-proxy
```

### Via pixi
```bash
pixi add --pypi mcp-streamablehttp-proxy
