Overview

A community MCP server focused on Polymarket, exposing 45 tools across market discovery, analysis, trading, portfolio management, WebSocket monitoring, and dashboard workflows. It is not an official Polymarket product. An agent builder plugs it in to build a prediction-market agent that can research and trade Polymarket markets; trading tools require the operator's own credentials and carry market risk.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

Install — not run by us — no falsifiable install+entry probe from deploy_spec

Runtime: python

git clone https://github.com/caiovicentino/polymarket-mcp-server.git
cd polymarket-mcp-server
python -m venv venv && source venv/bin/activate
pip install -e .
python -m polymarket_mcp.server

You supply: POLYGON_PRIVATE_KEY + POLYGON_ADDRESS (live trading only — DEMO_MODE=true runs market discovery/analysis read-only without a wallet)

MCP invocation: {"mcpServers":{"polymarket":{"command":"/path/to/venv/bin/python","args":["-m","polymarket_mcp.server"],"cwd":"/path/to/polymarket-mcp-server"}}}

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 46 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Every one of them passed, so the rate covers them too.

A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
