WHAT IT DOES

What port_scanner_aggregate does on APIMesh MCP Server

AI agents invoke port_scanner_aggregate to trigger actions in APIMesh 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 port_scanner_aggregate needs a policy

Port scanning actively probes external network infrastructure, triggering real-world reconnaissance operations against potentially third-party systems. This constitutes execution of external network operations whose effects depend on arguments (target IPs/CIDRs). Misuse by an AI agent could constitute unauthorized scanning of systems the operator does not own, with potential legal and security implications.

Verdict

port_scanner_aggregate Rate-limited

port_scanner_aggregate 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.

FAQ

Questions about port_scanner_aggregate

What does the port_scanner_aggregate tool do? +

Deep scan of a list of IP addresses or CIDR ranges with multi-source aggregation and vulnerability scoring. It is categorised as a Execute tool in the APIMesh MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on port_scanner_aggregate? +

Register the APIMesh MCP Server MCP server in PolicyLayer and add a rule for port_scanner_aggregate: 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 APIMesh MCP Server. Nothing to install.

What risk level is port_scanner_aggregate? +

port_scanner_aggregate is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit port_scanner_aggregate? +

Yes. Add a rate_limit block to the port_scanner_aggregate 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.

How do I block port_scanner_aggregate completely? +

Set action: deny in the PolicyLayer policy for port_scanner_aggregate. 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.

What MCP server provides port_scanner_aggregate? +

port_scanner_aggregate is provided by the APIMesh MCP Server MCP server (mbeato/apimesh). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
