MCP Router

A secure, enterprise-grade Model Context Protocol (MCP) server aggregation platform built with Electron.

Overview

MCP Router acts as a centralized gateway for managing multiple MCP servers, providing:

  • Server Aggregation: Connect and manage multiple MCP servers from a single interface

  • Policy-Based Access Control: Fine-grained control over tool and resource access

  • Token Authentication: Secure API token management with scoping and expiration

  • Approval Workflows: Human-in-the-loop approval for sensitive operations

  • Rate Limiting: Protect against abuse with configurable rate limits

  • Audit Logging: Complete audit trail of all operations
