MCProxy

What it does

MCProxy acts as a centralized gateway for Model Context Protocol (MCP) servers. It aggregates tools from multiple upstream servers (both stdio and HTTP) and exposes them through a single streamable HTTP interface, allowing AI clients to interact with a unified toolset.

Tools

• Tool Aggregation: Merges tool lists from multiple backend servers.
• Dynamic Updates: Automatically syncs when upstream servers signal toolListChanged.
• Intelligent Search: Provides on-demand tool discovery and filtering when the total tool count is high.
• Security Middleware: Intercepts requests to block calls based on custom security rules.
• Logging & Monitoring: Tracks operation timing and payloads per server.

Installation

Add the following to your claude_desktop_config.json:

{
  "mcpServers": {
    "mcproxy": {
      "type": "http",
      "url": "http://127.0.0.1:8081/mcp"
    }
  }
}

(Note: Requires running the MCProxy binary with a configuration file first)
