MCPOSimpleServer MCP Server

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.

How to use MCPoSimpleServer?

MCPoSimpleServer runs as a Docker container built on Debian 13 with a FastAPI/Python 3.13 server. Configuration is handled via a JSON file, and tools can be launched using uvx or npx. Users can define their own MCP servers with custom environment variables and access tools through SSE, Swagger REST, or OpenAPI endpoints.

Key features of MCPoSimpleServer

• Local Docker container with a single SSE-MCP connection
• Dynamic tool loading and filtering (whitelist/blacklist)
• Access via SSE, Swagger REST, and OpenAPI.json (OpenWebUI‑compatible)
• Each MCP server runs in its own thread for isolation
• JSON‑based configuration – no database required
• Bearer admin hack for simple authorization during testing

Use cases of MCPoSimpleServer

• Running and testing MCP tools locally in a secure, containerized environment
• Exposing MCP tools to LLM applications via standard APIs (SSE, REST)
• Integrating with OpenWebUI through OpenAPI endpoints
• Rapid prototyping and iteration with custom environment variables per tool
• Selective tool exposure using dynamic whitelist/blacklist filtering
