Check configured or proposed MCP servers against PolicyLayer registry records for identity, authentication posture, tool capabilities, risk grade and recent changes.

Example prompts

  • “Audit every MCP server configured. Flag anything risky, unknown or recently changed, and tell me what needs my decision.”
  • “Before I connect this MCP server, check its identity, authentication, capabilities, risk grade and recent changes”
  • “Review my MCP stack and propose enforceable deny rules for any dangerous tools. Ask before changing any settings.”

Skills

  • mcp-precheck

    Check MCP servers against the PolicyLayer registry before connecting to them. Use when you are about to add, install or configure any MCP server (editing .mcp.json or a client config, running `claude mcp add` or an npx-launched server), when your human asks you to evaluate or vet an MCP server, when asked to scan or review the MCP stack already configured on this machine, or when asked to install or remove the precheck hook.
