WHAT IT DOES

What run_mapcidr does on Pentester-MCP

AI agents invoke run_mapcidr to trigger actions in Pentester-MCP. 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.

RISK

Why run_mapcidr is rated High

MapCIDR manipulates and expands CIDR ranges, typically used in reconnaissance workflows. While ostensibly for network mapping, it executes external binaries whose effects depend on supplied network ranges—the core Execute category. Severity is high because reconnaissance tools enable downstream attacks; misuse could target unintended networks or generate network traffic that violates laws or contracts.

From the tool's definition Tool named 'run_mapcidr' on a penetration testing server described as enabling 'autonomous execution' of 'reconnaissance' tools. MapCIDR is a CIDR utility tool for IP range manipulation and scanning.

RECOMMENDED RULE

The rule that runs run_mapcidr safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Pentester-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For run_mapcidr, this is the rule to start with:

run_mapcidr Rate-limited

run_mapcidr 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.

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Pentester-MCP, apply this rule, and every run_mapcidr call is checked against it from then on.

FAQ

Questions about run_mapcidr

What does the run_mapcidr tool do? +

run_mapcidr is a execute tool on the Pentester MCP server. It is categorised as a Execute tool in the Pentester-MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on run_mapcidr? +

Register the Pentester MCP server in PolicyLayer and add a rule for run_mapcidr: 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 Pentester-MCP. Nothing to install.

What risk level is run_mapcidr? +

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

Can I rate-limit run_mapcidr? +

Yes. Add a rate_limit block to the run_mapcidr 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 run_mapcidr completely? +

Set action: deny in the PolicyLayer policy for run_mapcidr. 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 run_mapcidr? +

run_mapcidr is provided by the Pentester MCP server (halilkirazkaya/pentester-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
