Mcpo Simple Server

A Python-based LLM server that implements the Model Context Protocol (MCP).

🤔 What is MCPoSimpleServer?

MCPoSimpleServer is a lightweight, asynchronous API platform for running and managing MCP tools in isolated, secure environments. It implements the Model Context Protocol (MCP) for seamless integration with LLM applications.

✨ Key Features

• ✨ Local Docker container – your own local Docker container with a single SSE-MCP connection
• ⚡ Support quick and easy load any MCP tool launched via uvx or npx
• 🔄 Dynamic tool loading and filtering (whitelist/blacklist)
• 🌐 Access to MCP tools via SSE, Swagger REST, and OpenAPI.json (compatible with OpenWebUI)
• 🐳 Tool isolation – each tool runs in its own thread
• 🗄️ JSON-based configuration – easy to edit and portable
• 🧑‍💻 Ability to launch your own MCP server with custom ENV parameters
• 🛡️ Bearer admin hack – simple admin authorization (ideal for testing and quick changes)
• 📝 Async FastAPI Python server with full type hints for code clarity and safety
• ✅ PyTest – fast and easy verification of changes on a running server

🎉 What we have now

• 🔗 Docker container built on Debian 13 with FastAPI/Python 3.13 server
• ⚡ Support quick and easy load any MCP tool launched via uvx or npx
• 🌐 Access to MCP tools via SSE, Swagger REST, and OpenAPI.json (OpenWebUI compatible)
• 🆒 SupervisorD controlled by ENV allows running SSHD + Xfce + noVNC (desktop via web/port 6901, ~260MB)
• 🔄 Dynamic tool loading and filtering from MCP server (whitelist/blacklist)
• 🧵 Each MCP server runs in its own thread
• 🗄️ No need for a database – JSON configuration for easy editing and portability
• 🧑‍💻 Users can define their own MCP server with custom ENV (auto-detected via Auth Bearer)
• 🛡️ Env Bearer Admin Hack – configurable env simulating Bearer admin (ideal for tests and quick changes)
• 📝 Built entirely on FastAPI Python + Pydantic for code clarity and safety
• ❌ Custom SSE stack based only on FastAPI (no Starlette)
• ✅ PyTest – tests run a live server instance and perform tests on a real running server (no mocking!)
