Security Report

4.6
Use Caution4.6High Risk

BlockRun MCP is a developer-facing gateway exposing paid AI, search, and on-chain tools with a wallet-based or API-key payment model, and its permissions (network, wallet keys, filesystem for ~/.blockrun session) match its stated purpose. The main concerns are the inherent risk of a server that holds a self-custody wallet and can place real Polymarket trades and spend USDC, mitigated by budget limits and confirm-gating; the visible code shows no obvious exfiltration, hardcoded secrets, or shell injection, though only a truncated portion of the source was provided for review. Supply chain analysis found 8 known vulnerabilities in dependencies (0 critical, 4 high severity). Package verification found 1 issue.
