Secret and credential scanner
AI agents call trufflehog to retrieve information from PenTest MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Trufflehog is a well-known security scanning tool that searches through files and repositories to identify exposed secrets and credentials. It performs static analysis without executing code, modifying data, or triggering external operations. The blast radius is low because scanning itself has no side effects—it only reads and reports findings.

trufflehog is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the trufflehog rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for trufflehog. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
trufflehog is provided by the PenTest MCP Server MCP server (mohitsahoo/mcptoolforwebvulnerabilities-). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
