# 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.
