Clearmarket MCP server

What it does

ClearMarket provides institutional reference data for prediction markets on Polymarket and Kalshi. It grades market resolution clarity, links identical markets across venues, documents resolution sources, and organizes markets into structured events with catalyst dates. It is for research, risk, and data teams working with prediction market data at scale.

• Look up a prediction market by ID, URL, or ticker and get its resolution source, clarity grade, and any matching contracts on the other venue.
• Search for all markets related to a topic—like Fed rate decisions—and see them grouped by event with catalyst dates and pricing from both venues.
• Ingest daily market signals and institutional-grade reference data into risk or research workflows without custom parsing of two separate venue APIs.

Before you enable it

An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
