MCP Precheck
Security checks across malware telemetry and agentic risk
Overview
This skill is a disclosed MCP-server precheck helper that runs PolicyLayer lookups before connecting to MCP servers and asks for approval before making persistent changes.
Before installing, understand that this skill relies on the external PolicyLayer CLI and registry, and MCP server names or package identifiers may be looked up remotely. The optional hook changes Claude settings and should only be installed if you want automatic prechecks on future MCP additions.
