NautilusTrader leads Polymarket data repos by a 10× popularity margin; four of the top ten ship native MCP

Asked (summary):

Select the 10 best GitHub repositories (by stars + forks) that download Polymarket data, preferring those with LOB (limit order book) schemas and full category coverage, and those using MCP. For each, give 10 bullet points covering Windows 11 use, main features, strengths and weaknesses, plus basic instructions to integrate with major AIs.

The ten rows below are the top 10 of 26 active, relevant candidate repositories validated through live-web research — not every Polymarket repo on GitHub. Stars and forks are a live GitHub API snapshot taken 2026-10-14 UTC; popularity ranks the list, while LOB depth, category coverage, and native MCP appear as preference badges. LOB means limit order book: matched trades or OrderFilled events are not equivalent to reconstructable full-depth L2 history.

Method: 10 repositories (top of 26 active relevant candidates from live-web research), ranked by GitHub stars + forks snapshot of 2026-10-14 UTC via the GitHub API; metrics can change. LOB/category/MCP grades come from repository pages plus one independent corroborating source per row (10 distinct primary URLs, 9 corroborating hosts; no URL backs more than one row). Long evidence text is trimmed for space; blank fields were left unverified rather than invented.
