# `Parapet.Plug.MCP`
[🔗](https://github.com/szTheory/parapet/blob/v1.0.0/lib/parapet/plug/mcp.ex#L1)

A Plug to handle incoming MCP connections via HTTP SSE.
Accepts JSON-RPC POST requests and streams responses back as SSE chunks.

> #### Experimental {: .warning}
>
> This module is **experimental** in v1.x. Its API may change in a minor release with a
> single-version notice in CHANGELOG.md. See
> [Stability & Deprecation Policy](stability.html) for details.

**Security Note:**
Authentication and authorization to the MCP endpoint must be handled by the
host application's router pipeline *before* requests reach `Parapet.Plug.MCP`.
This plug does not perform any authentication checks internally.
