@mcp-stack/proxy v1.0.3

mcp-proxy

Implements protocol conversion between SSE and stdio

Read this in other languages: English | 简体中文

Motivation

When either the client or the server does not support a particular protocol, protocol conversion becomes necessary. For example, some typical scenarios include:

1. Claude or some other clients does not support the SSE protocol.
2. We want to deploy an MCP Server that only supports STDIO.

Now you can use this tool to solve the problem.

Usage

• SSE to STDIO

 npx @mcp-stack/proxy stdio-to-sse https://your-mcp-server/sse

• STDIO to SSE

npx @mcp-stack/proxy sse-to-stdio node /path/to/your/mcp/script.js --port 8080
