Free MCP server · MIT

Check the MCP servers you already use, from your agent

Add the TrustedMCP MCP server to Claude, Codex, Gemini CLI, Cursor, VS Code or Windsurf. Ask it to check your MCP security and every server in it gets its security grade, A to D, with the one thing to fix first.

  • Reads your config on your machine. Tokens, env vars and file paths stay there.
  • Suggests graded alternatives for a C or D server.
  • Takes a free key with your email. Scoped, and you can revoke it.
