WHAT IT DOES

What run_certipy does on Pentester-MCP

AI agents invoke run_certipy to trigger actions in Pentester-MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why run_certipy is rated High

Certipy is a post-exploitation and privilege escalation tool targeting Active Directory certificate services. Running it autonomously executes external operations whose effects depend on arguments (target selection, attack type, scope). While the description is empty, the tool name combined with server context and sibling tools clearly indicates this executes penetration testing operations.

From the tool's definition Tool name 'run_certipy' invokes Certipy, an Active Directory exploitation tool used for penetration testing.

RECOMMENDED RULE

The rule that runs run_certipy safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Pentester-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For run_certipy, this is the rule to start with:

run_certipy Rate-limited

run_certipy stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Pentester-MCP, apply this rule, and every run_certipy call is checked against it from then on.
