Polymarket MCP — Live Markets & Prices

Access the world's largest prediction market platform directly from your AI assistant.

What is Polymarket?

Polymarket is a decentralized prediction market platform where people trade on the outcomes of real-world events. Market prices represent the crowd's probability estimate for each outcome — making them some of the most accurate real-time forecasts available.

Why this MCP server?

Most tools that access Polymarket use cached API data with stale prices. polymarket-mcp pulls live prices directly from the CLOB v2 order book — the same data traders use — so you always get the most accurate numbers.

APIs used

API	URL	Purpose
Gamma API	`https://gamma-api.polymarket.com`	Market catalogue, search, metadata
CLOB v2	`https://clob.polymarket.com`	Live order-book midpoint prices, price history

Smart slug resolution

When you search for markets, you get back event slugs. These same slugs work directly with get_market_details and get_current_prices — the server automatically resolves event slugs → most active embedded market, so you never need to manually look up a separate ID.

search_markets("bitcoin")
  → slug: "when-will-bitcoin-hit-150k"

get_current_prices("when-will-bitcoin-hit-150k")   ← works directly
get_market_details("when-will-bitcoin-hit-150k")   ← works directly
get_price_history("when-will-bitcoin-hit-150k", "7d")  ← works directly

Price history sparklines

get_price_history("will-bitcoin-hit-150k-by-june-30-2026", "24h")
