A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

⚠️ Notice: Quantish is winding down. The Quantish platform (quantish.live) is shutting down. This MCP server is self-hosted and will continue to work independently, but the Quantish team will no longer be maintaining or updating this project. If you're building in the prediction market space and need real-time data infrastructure, check out polynode.dev.
Self-hosted MCP server for trading on Polymarket prediction markets.
This package provides an MCP (Model Context Protocol) server that enables AI agents to trade on Polymarket prediction markets via the Polygon network.

-H "x-api-key: YOUR_API_KEY" \
-d '{
