Setup · 2 min

One install.
Every AI tool gets it.

MCP (Model Context Protocol) lets Claude, Cursor, and Codex call datapolymarket as a native tool — no prompt boilerplate, no copy-pasting keys, no glue code. Set up once, ask in English forever.

What is MCP?

A standard way for AI to call APIs as tools.

Think of MCP like USB for AI. Plug in a server, every compatible AI tool sees the tools it provides — no per-tool integration. Anthropic invented it; Cursor, Codex, Cline, and the rest support it.

Our MCP server exposes 5 tools that map to our API. Your AI calls them by name.

Talk to your AI

That's it. The 5 tools are now native. Try one of these:

›Find me 3 mispriced Polymarket weather markets resolving today.
›Is there a BTC oracle-vs-spot arb on Polymarket right now?
›What's the current YES probability for the NYC heat market?
›Summarize my edge across all open weather markets in cities I follow.
After setup

It looks like this.

Your AI sees datapolymarket as native tools. You ask, it calls, you get the analysis. No prompt-engineering tricks, no API keys in messages.
