What netscan does on Claude C2
AI agents call netscan to retrieve information from Claude C2 without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why netscan is rated Low
Network scanning is a read-only reconnaissance operation that queries and retrieves information about networked systems without modifying or executing code. However, the severity is medium rather than low because network scanning is often a precursor to attacks and could be misused by an AI agent to map target systems for exploitation.
From the tool's definition Tool name 'netscan' and description 'Scan network for hosts' indicate network reconnaissance/discovery operations that retrieve information about network topology and host availability.
Attacks that exploit this kind of access
The rule that runs netscan safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Claude C2, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For netscan, this is the rule to start with:
netscan is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Claude C2, apply this rule, and every netscan call is checked against it from then on.
Questions about netscan
Scan network for hosts. Auto-selects client. It is categorised as a Read tool in the Claude C2 MCP Server, which means it retrieves data without modifying state.
Register the Claude C2 MCP server in PolicyLayer and add a rule for netscan: 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 Claude C2. Nothing to install.
netscan is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the netscan 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 netscan. 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.
netscan is provided by the Claude C2 MCP server (0xyg3n/claude-c2). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
