@marketmaster/mcp

MCP server for the MarketMaster prediction-market data API. Pull live edges, arbitrage spreads, market snapshots, and the whale feed (Kalshi and Polymarket) straight into Claude or Cursor.

Tools

• mm_edges — mispriced edges, ranked
• mm_markets — latest market snapshots
• mm_market — one market + its edges
• mm_arbitrage — cross-platform spreads
• mm_whales — large real-money trades
• mm_status — your tier, limits, usage

Setup

Get an API key at https://marketmaster.live/dashboard (looks like mmk_live_...).

      "args": ["-y", "@marketmaster/mcp"],
      "env": { "MARKETMASTER_API_KEY": "mmk_live_your_key" }
