Any Chat Completions MCP server

Let your AI ask another AI service a question and bring the answer back into your chat.

This is a small helper that connects your AI assistant to other AI chat services, like OpenAI, Perplexity, Groq or xAI. Once it is set up, you can ask your assistant to pass a question along to one of those services and show you what it says. It is handy if you already use one AI tool but want a second opinion from a different one without switching apps.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you using what it already knows. An MCP server is a small helper program that gives your AI a new skill or a connection to another service. This one connects your AI to a chat service you choose, such as OpenAI or Perplexity, using a key and web address you provide. After that, your AI can send a question over to that service and read the reply back to you.

What this MCP server does

You type a question in your chat, like you normally would. Your AI notices you want an answer from another service and hands the question to this helper. The helper sends your question to the chat service you set up, using the key and web address from your settings. That service writes an answer and sends it back. The helper passes the answer to your AI, and your AI shows it to you in the chat.

Flow diagram: you ask your AI “Ask Perplexity what the weather is like in Paris today”, the Any Chat Completions MCP server connects it to Another AI service, and you get back the other AI's answer.

What you can do with it

What it gives back to you

You get the other service's answer written out in your chat, like a normal reply. It is usually plain text, sometimes with a short list or a few paragraphs. Your AI may add a line saying which service the answer came from. Nothing is saved anywhere by this helper; it just passes the reply through.

Before you start

What you need

The Claude desktop app or another app that supports MCP servers
An account and an API key from the chat service you want to use, such as OpenAI or Perplexity (an API key is a kind of password for apps; the service gives you one on its website)
The web address of that service's chat endpoint, which the service's instructions will show you
Node.js installed on your computer if you plan to run it with npx

Good to know

Each question you send goes to the other service and may count against your paid plan there, so keep an eye on your usage.
