How to get AI prices inside Claude, ChatGPT and Cursor: connect the AI Rate Card MCP server

Updated Nov 8, 2026

An assistant answers price questions from memory, and AI prices change every week. The AI Rate Card MCP server gives Claude, ChatGPT, Cursor or any MCP client today's prices of every model at every seller, with a link to the card each number came from.

Two addresses

https://airatecard.com/mcp - open to everyone, no sign-in, guest limits. Enough for most people.
https://airatecard.com/mcp/account - works under your AI Rate Card account (your limits); you sign in once on this site, the assistant never sees your password, and you can revoke the access in your account.

Claude (claude.ai and the desktop app)

Settings → Connectors → Add custom connector.
Name it "AI Rate Card" and paste https://airatecard.com/mcp (or the account address).
For the account address leave the OAuth client on "Register automatically"; Claude opens this site's sign-in page - sign in and press Allow.
In a chat, turn the connector on and ask.

ChatGPT

Settings → Connectors, with developer mode on → create a connector.
Paste the address and choose OAuth authentication for the account address (none for the open one).
Sign in on this site when ChatGPT opens it, press Allow.

Claude Code

claude mcp add --transport http ai-rate-card https://airatecard.com/mcp - for the account address, type /mcp inside Claude Code afterwards and choose Authenticate.

Cursor and VS Code

Put the server in mcp.json: `` { "mcpServers": { "ai-rate-card": { "url": "https://airatecard.com/mcp" } } } `` For the account address the client opens this site's sign-in page on the first call.

What to ask

"What is the cheapest provider of Claude Sonnet 5.5 right now?"
"Compare GPT-5.5 and Gemini 3.1 Pro for 50M input and 5M output tokens a month."
"Which reasoning models are class A or better, and which of them is cheapest?"
"How much do 1,000 images cost on the cheapest image models?"
"Is Claude Pro cheaper than the API if I send 40 messages a day?"

Every answer carries a card link and a ready citation line ("Source: AI Rate Card, ..."), so you can check the number. The full list of tools and code for your own agent: Documentation.
