What inject_portscan does on Cobalt Strike MCP Server
AI agents invoke inject_portscan 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 inject_portscan is rated High
Port scanning is an active network operation that probes external systems, fitting the Execute category. In the context of a Cobalt Strike red team server with beacon control, this tool injects and runs scanning code on or through a compromised beacon, making it a significant offensive capability.
From the tool's definition 'inject_portscan' and 'Perform port scan' — actively executes network reconnaissance by injecting and running a port scanning operation against target hosts
Attacks that exploit this kind of access
The rule that runs inject_portscan safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Cobalt Strike MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For inject_portscan, this is the rule to start with:
inject_portscan 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 Cobalt Strike MCP Server, apply this rule, and every inject_portscan call is checked against it from then on.
Questions about inject_portscan
Perform port scan. It is categorised as a Execute tool in the Cobalt Strike MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Cobalt Strike MCP Server MCP server in PolicyLayer and add a rule for inject_portscan: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Cobalt Strike MCP Server. Nothing to install.
inject_portscan is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the inject_portscan rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for inject_portscan. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
inject_portscan is provided by the Cobalt Strike MCP Server MCP server (mickeydb/cobalt-strike-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
