[Proposal]MCP Adapter for Hertz

## 1. Background

MCP is becoming a mainstream protocol for AI tool calling. Other language frameworks have already completed integration (FastAPI-MCP, Spring AI, trpc-mcp-go). Hertz has built-in SSE support, providing the necessary technical foundation. `hertz-contrib` is the officially recognized third-party extension library for Hertz, and this project, as an MCP protocol adaptation layer, aligns with its positioning.

## 2. Goal

Provide a lightweight adapter layer that allows Hertz users to expose existing Handlers as MCP tools with minimal effort.

## 3. Current Status

A working initial version has been completed, with the core workflow fully functional and validated through MCP Inspector and AI IDE. The codebase is small, depends only on Hertz, and has a solid foundation for further iteration.

## 4. Next Steps

Refine gradually based on community feedback, with the hope of driving this effort to completion.

Start by reviewing the linked MCP-adapter repository and Hertz's existing SSE support; the issue names no files, tests, or entry points in this repository. Determine whether the external initial version can be brought into hertz-contrib, and consider the work done only when the adapter exposes Hertz handlers as MCP tools with the stated validation preserved.
