MCP server security scorecards

Independent, static security reads of well-known public MCP servers — each one scans the tool definitions the server advertises for prompt-injection / tool-poisoning patterns (OWASP LLM01/LLM08) and checks them against the Anthropic Claude Connector Directory review criteria. Every scorecard is dated and re-runnable by you in one keyless call; results are point-in-time (tool definitions drift).

Method and the rest of the catalogue: vet an MCP server before your agent trusts it. Independent scans by Grey Ridge Signals.
