Overview

This is a disclosed prediction-market trading skill that defaults to paper trading, with real-money trading gated by an explicit live flag.

Install only if you want an agent to analyze prediction-market data and potentially place trades. Keep SIMMER_API_KEY protected, run in paper mode first, and enable `--live` only with low position limits and clear human oversight.

Medium

• Category: MCP Least Privilege
• Confidence: 95% confidence
• Finding: The skill documentation indicates use of environment variables and outbound network access (`SIMMER_API_KEY`, Polymarket leaderboard/data APIs, and `simmer-sdk`) but does not declare corresponding permissions. Undeclared capabilities are dangerous because they bypass least-privilege review and can conceal access to secrets or external endpoints that an operator did not knowingly authorize.
