Cross-LLM MCP server

This is a helper that lets your AI assistant talk to other AI models for you. You can ask ChatGPT, Claude, Gemini, DeepSeek, Grok, Kimi, Perplexity, Mistral, and Hugging Face models from one place. It is handy if you like comparing answers or want a second opinion on something.

What this MCP server does

You type a request in your chat, like asking for a poem or an explanation. Your AI passes that request to this helper. The helper sends it to the model you picked, using your own account key for that service. The model writes an answer, and the helper hands it back so your AI can show it to you. You can also send the same question to every model at once and see them side by side.

• Look back at your past prompts and see simple usage statistics
• Delete old prompt logs or clear the whole history

Try asking your AI

• “Ask ChatGPT to explain quantum computing in simple terms”
• “Send this poem idea to all the models and show me each answer”
• “Use my coding model to review this function and suggest fixes”
• “Show me my last ten prompts to Claude”

What it gives back to you

You get the model's written answer right in your chat, just like a normal reply. When you ask several models at once, you get each one's answer labeled by provider so you can compare. The history and stats tools give you lists and simple numbers about what you have asked before. Preference tools confirm what settings you saved.
