What is the Prediction Markets API MCP server?

Prediction Markets API MCP server exists for a simple reason — assistants are far more useful when they can act on Prediction Markets API directly instead of describing what you should do. Prediction market odds from Polymarket. Active markets, probabilities, volume. x402.

What you get

Real-time prediction market odds from Polymarket and Kalshi. Active markets, probabilities, volume, categories. The betting intelligence layer agents need for event forecasting. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Setting it up

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.

What the assistant can call

Once Prediction Markets API is connected, these are the calls the assistant has available:

  • prediction_list_markets — POST
  • prediction_get_market_odds — POST
  • prediction_trending_markets — POST

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the prediction markets api mcp server does with a few real requests.

Choosing this one

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Prediction Markets API's toolset — prediction_list_markets, prediction_get_market_odds, prediction_trending_markets — is a fair guide to whether it matches your workflow. It is maintained by Br0ski777; worth a glance at recent repository activity before you build anything load-bearing on it.
