WHAT IT DOES

What run_rpcclient does on Pentester-MCP

AI agents invoke run_rpcclient 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_rpcclient is rated High

rpcclient is used to interact with Windows RPC services, enumerate shares, execute commands on remote systems, and perform reconnaissance. This is an Execute tool because it triggers external operations (RPC queries and interactions with remote systems) whose effects depend on the arguments provided.

RECOMMENDED RULE

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

run_rpcclient Rate-limited

run_rpcclient 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_rpcclient call is checked against it from then on.
