### Description (declared)

# Browse MCP Proxy

A proxy server that enables browser-based applications to connect to MCP (Model Context Protocol) servers. This proxy handles CORS, session management, and transport type conversion.

## Why This Proxy?

Browser-based applications face several challenges when connecting to MCP servers:

1. **CORS Restrictions**: Browsers enforce Same-Origin Policy, preventing direct connections to MCP servers on different origins.

2. **Session Management**: MCP's Streamable HTTP transport requires session IDs that browsers can't automatically manage across requests.

3. **STDIO Transport**: Browser JavaScript cannot spawn local processes, but this proxy can bridge that gap.

## Architecture

```
┌─────────────────┐
│  Browser/Tauri  │  (Inspector UI)
│  Frontend App   │
└────────┬────────┘
         │ 1. HTTP requests (same-origin or CORS-allowed)
         │ 2. X-MCP-Proxy-Auth header for security
