- ๐ Access to MCP tools via SSE, Swagger REST, and OpenAPI.json (compatible with OpenWebUI)
- ๐ณ Tool isolation โ each tool runs in its own thread
- ๐๏ธ JSON-based configuration โ easy to edit and portable
- ๐งโ๐ป Ability to launch your own MCP server with custom ENV parameters
- ๐ก๏ธ Bearer admin hack โ simple admin authorization (ideal for testing and quick changes)
- ๐ Async FastAPI Python server with full type hints for code clarity and safety
- โ PyTest โ fast and easy verification of changes on a running server
๐ What we have now
- ๐ Docker container built on Debian 13 with FastAPI/Python 3.13 server
- โก Support quick and easy load any MCP tool launched via `uvx` or `npx`
- ๐ Access to MCP tools via SSE, Swagger REST, and OpenAPI.json (OpenWebUI compatible)
- ๐ SupervisorD controlled by ENV allows running SSHD + Xfce + noVNC (desktop via web/port 6901, ~260MB)
- ๐ Dynamic tool loading and filtering from MCP server (whitelist/blacklist)
- ๐งต Each MCP server runs in its own thread
