AI agents call irr_route_lookup to retrieve information from Net without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
IRR lookups are standard read-only network diagnostic queries that retrieve public routing registry data. The tool has no side effects, does not execute code, modify data, or commit financial/destructive operations. Confidence is not higher due to empty description, but the naming pattern and sibling tools provide strong contextual evidence that this is informational/observational only.
From the tool's definition Tool name 'irr_route_lookup' indicates a lookup/query operation against IRR (Internet Routing Registry) data. The naming pattern matches sibling tools like 'bgp_route_lookup', 'bgp_prefix_origin', and 'dns_lookup' which are all read-only queries.
Attacks that exploit this kind of access
irr_route_lookup. It is categorised as a Read tool in the Net MCP Server, which means it retrieves data without modifying state.
Register the Net MCP server in PolicyLayer and add a rule for irr_route_lookup: 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 Net. Nothing to install.
irr_route_lookup 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 irr_route_lookup 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 irr_route_lookup. 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.
irr_route_lookup is provided by the Net MCP server (steelcutoatmeal/net-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
