The Multi LLM Cross-Check MCP Server is designed to facilitate cross-checking responses from multiple LLM providers simultaneously through a single interface. It supports parallel querying with providers such as OpenAI, Anthropic, Perplexity AI, and Google, and is integrated with Claude Desktop for streamlined usage.

Multi LLM Cross-Check MCP Server

A Model Control Protocol (MCP) server that allows cross-checking responses from multiple LLM providers simultaneously. This server integrates with Claude Desktop to provide a unified interface for querying different LLM APIs.

Features

  • Query multiple LLM providers in parallel
  • Currently supports:
    • OpenAI (ChatGPT)
    • Anthropic (Claude)
    • Perplexity AI
    • Google (Gemini)
  • Asynchronous parallel processing for faster responses
  • Easy integration with Claude Desktop

Prerequisites

  • Python 3.8 or higher
  • API keys for the LLM providers you want to use
  • uv package manager

Using the MCP Server

  • The server automatically starts with Claude Desktop
  • Use the cross_check tool by asking to "cross check with other LLMs"
  • Provide a prompt to receive responses from all configured LLM providers

Error Handling

  • Providers without an API key are skipped
  • API errors are caught and returned in the response
  • Each LLM's response is independent.
