# spawn_command Execute a command on a beacon (spawns in new process) Agent View of the PolicyLayer registry record for `spawn_command`. HTML page: https://policylayer.com/tools/mickeydb-cobalt-strike-mcp/spawn-command ## Facts - Tool: `spawn_command` - Server: Cobalt Strike MCP Server (`mickeydb/cobalt-strike-mcp`) — https://policylayer.com/tools/mickeydb-cobalt-strike-mcp.md - Homepage: https://github.com/MickeyDB/Cobalt-Strike-MCP - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "spawn_command", "arguments": {} } } ``` ## Why spawn_command is rated High This tool directly executes commands on remote systems under the control of Cobalt Strike beacons. Command execution on compromised hosts is the canonical Execute category and represents critical risk: an AI agent could run arbitrary malicious commands, escalate privileges, establish persistence, exfiltrate data, or pivot to other systems. From the tool's own definition: "Tool description states 'Execute a command on a beacon (spawns in new process)' — explicit execution of arbitrary commands on compromised systems. This is part of a red team operations toolkit (Cobalt Strike) designed for offensive security." ## Use case AI agents invoke spawn_command to trigger actions in Cobalt Strike 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. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
