Polymarket Agent MCP: 48-tool MCP server with preview and live trading

MCP server that lets Claude Code, Cursor and other local AI clients read Polymarket markets, track wallets, backtest and run copy-trading loops. It starts in a preview mode that records simulated trades in SQLite; live mode signs CLOB orders with your own wallet key and enforces safety and daily-budget checks.

Two-LLM analyst and challenger pipeline for Polymarket (finished paper experiment)

FastAPI, PostgreSQL and Redis pipeline where a Claude analyst and an OpenAI challenger each estimate a Polymarket market's probability and a rule-based consensus compares them with the price. It ran as a no-money paper experiment from June to October 2026; the author's write-up (in Russian, self-reported) found no edge over market prices and publishes the data and lessons.

Polymarket Edge Scanner: read-only, paper-only scanner on Cloudflare's free tier

TypeScript Cloudflare Worker that discovers liquid Polymarket markets via the public Gamma API, prices them from CLOB order books, flags possible value with an explainable engine, and simulates paper orders with fees, spread and slippage. It uses D1 for storage and Workers AI to read resolution rules, and tracks its own calibration. It never signs transactions or asks for a wallet key.
