Overview

What is MCP Facade?

MCP Facade is a facade service that provides a unified interface for managing and interacting with multiple MCP (Machine Conversation Protocol) servers. It acts as a single entry point for agents to communicate with various MCP servers while providing JWT-based authentication and fine-grained access control.

How to use MCP Facade?

Clone the repository, install dependencies with pnpm i, copy .env.example to .env, edit as needed, then run pnpm dev. Register MCP servers via the /api/mcp/servers endpoint and interact with tools through the /api/mcp endpoint. The server is also compatible with the oap-langgraph-tools-agent for use with LangGraph.
