A-D grades for MCP servers, inside your agent
TrustedMCP is a free, open-source MCP server that brings TrustedMCP's grades into Claude, Cursor, VS Code and other MCP clients. Ask "check my MCP setup" or "what grade does @playwright/mcp get?" and your agent answers with an A-D grade per server, what to fix first, and better-graded servers in the same category. Four read-only tools: look up a server, check every server in your MCP config, find graded alternatives, and read an official MCP Registry entry with its reported advisories. Each grade is an assessment from public signals (login, upkeep, known CVEs, connection), a starting point for your own review, not a code audit. Runs locally with npx or as a hosted remote at trustedmcp.io/mcp. MIT licensed, no account needed.
