spawn_net_view · Cobalt Strike MCP Server MCP: Risk & Policy

WHAT IT DOES

What spawn_net_view does on Cobalt Strike MCP Server

AI agents invoke spawn_net_view 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.

WHY IT NEEDS A POLICY

Why spawn_net_view needs a policy

In Cobalt Strike, 'spawn' operations fork a new process (sacrificial process) to execute actions. This tool spawns a process to enumerate network resources, which is an active execution operation with significant reconnaissance implications in a red team/adversarial context. While it reads network info, the spawn mechanism means it executes code in a new process, making Execute the appropriate category.

From the tool's definition 'spawn mode' and 'View network resources' — spawns a process/beacon to perform network reconnaissance

spawn_net_view Rate-limited

spawn_net_view 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.
