ToolCheck is M8ven's trust layer for the MCP ecosystem. Give it a GitHub URL or npm package name and it returns an independent trust score (0–100) and a clear verdict (Trusted / Caution / Concern), backed by static code analysis, runtime behavioral observation in a sandbox, CVE scanning, and a semantic check comparing the tool's declared behavior against what its code actually does — catching the gap between "read-only market data" and code that can move your funds.
