# spawn_shellcode Execute shellcode (spawn mode) Agent View of the PolicyLayer registry record for `spawn_shellcode`. HTML page: https://policylayer.com/tools/mickeydb-cobalt-strike-mcp/spawn-shellcode ## Facts - Tool: `spawn_shellcode` - 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_shellcode", "arguments": {} } } ``` ## Why spawn_shellcode is rated High This tool executes arbitrary shellcode in spawn mode, which runs code whose effects are entirely determined by the shellcode payload itself. While not strictly irreversible like Destructive actions, shellcode execution is a highest-impact Execute action—it can lead to privilege escalation, system compromise, malware installation, or any attack an adversary designs. From the tool's own definition: "Tool name 'spawn_shellcode' and description 'Execute shellcode (spawn mode)' explicitly indicate arbitrary code execution." ## Use case AI agents invoke spawn_shellcode 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**.
