Add Polydev to Claude and ChatGPT

The chat app keeps its own model. Polydev brings the rest: Claude, GPT, Gemini, Grok and more, and every answer says what paid for it. The link has four tools:

ask_model

Sends a prompt to one model, or several, and returns each answer with what paid for it. The older name get_perspectives still works.

list_models

The models you can reach right now, and what pays for each.

search_x

Recent public posts on X. Read-only, and it needs your own xAI API key.

rank_perspectives

Ranks the answers, best first, when you ask. Rankings feed the public leaderboard as counts.

   Sign in to Polydev and approve when ChatGPT asks.

Which ChatGPT plans and apps can use custom MCP servers is up to OpenAI and changes over time.

Ask in plain words and name the model, or mention Polydev. Claude and ChatGPT call it when you ask, or may offer to.

• In Claude

  “Have GPT check this plan and list anything it would change.”

• In ChatGPT

  “Ask Claude to rewrite this in plain English.”

• In either

  “Ask GPT and Gemini what this contract clause means, then tell me where they disagree.”

• In either

  “Search X with Polydev for what people are saying about this week’s outage, then summarise it.”

Which models you can reach depends on what you set up in your dashboard. Ask for list_models to see them.

Polydev is free: there are no plans, tiers or credits to buy. Each request uses the first of these you have set up, and every answer ends with what paid for it, for example Paid by: your API key.

Your API keys

OpenAI, Anthropic, Google, xAI or OpenRouter, added in your dashboard. The provider bills you directly.

10 free requests

On Polydev, up to $1 in total. No card.

Claude does not use Polydev in a chat

Check that the connector shows as connected in Settings → Connectors and that Polydev is turned on in the chat's tools menu. Then name the model, or mention Polydev, in your request.

Sign-in fails or keeps asking again

Disconnect the connector, revoke the old entry under Connected apps, and connect again.

A model is missing, or the free requests ran out

Add your own API keys or an OpenRouter key in your dashboard. Ask for list_models to see what you can reach and what pays for each.
