MCP Servers
by devsapp
MCP Servers on Serverless provides templates and a proxy to enable existing MCP servers using STDIO to work with SSE, allowing them to be used in web applications. The mcp-proxy facilitates the transition of MCP Server code to SSE mode without requiring any code changes.

MCP Servers on Serverless
MCP 协议中有 STDIO 与 SSE 两种传输机制，大致如下:
STDIO模式架构
[客户端] → stdin请求 → [MCP服务器] → stdout响应 → [客户端]
SSE模式架构
HTTP POST请求
↗---------------→
[Web客户端] [MCP服务器]
↖-----------------↙
SSE事件流推送
当前市场中存量 MCP Server 绝大部分采用 STDIO 传输机制实现，为了能够实现存量的 MCP Server 代码无需任何改变即可转为 SSE 模式，我们设计了 mcp-proxy，工作原理如下图:
