WHAT IT DOES

What start_msf_handler does on Pentester-MCP

AI agents invoke start_msf_handler 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 start_msf_handler is rated High

A Metasploit handler is fundamentally an Execute tool—it establishes connections to compromised systems and facilitates remote code execution on those targets. The tool enables an AI agent to catch reverse shells from successful exploits and execute arbitrary commands on victim machines.

From the tool's definition Tool name 'start_msf_handler' refers to Metasploit Framework's handler, which is used to catch and manage reverse shells and meterpreter sessions from exploited targets.

RECOMMENDED RULE

The rule that runs start_msf_handler 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 start_msf_handler, this is the rule to start with:

start_msf_handler Rate-limited

start_msf_handler 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.
