AI agents call peeringdb_network 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.
This tool performs a passive lookup of publicly available network information in PeeringDB based on an ASN (Autonomous System Number). It retrieves data without modifying, executing code, deleting resources, or affecting financial systems. The worst-case misuse scenario is gathering reconnaissance data, which has limited blast radius. Severity is low because the data is public and read-only.
From the tool's definition Tool description states 'Look up a network in PeeringDB by ASN' — a query operation that retrieves data from a public database with no side effects.
Attacks that exploit this kind of access
Look up a network in PeeringDB by ASN. 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 peeringdb_network: 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.
peeringdb_network 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 peeringdb_network 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 peeringdb_network. 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.
peeringdb_network 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.
