cme_rdp · CrackMapExec MCP Server MCP: Risk & Policy

WHAT IT DOES

What cme_rdp does on CrackMapExec MCP Server

AI agents invoke cme_rdp to trigger actions in CrackMapExec MCP Server. 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.

WHY IT NEEDS A POLICY

Why cme_rdp needs a policy

This tool performs remote execution of RDP operations and captures screenshots from target systems. While it does not permanently destroy data (Destructive), move money (Financial), or merely read data without side effects (Read), it actively executes operations on external systems whose effects depend on the arguments provided (target host, protocol version, command options).

From the tool's definition Tool description explicitly states 'Execute RDP protocol operations' and 'screenshot capabilities'. The sibling tools on this penetration testing server (cme_creds, cme_ldap, cme_mssql, cme_ssh, cme_winrm, cme_wmi) all perform Execute-class operations.

cme_rdp Rate-limited

cme_rdp 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.
