AI agents call ip_contains 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.
Given the empty description and the context of a network engineering MCP server focused on BGP analysis and DNS queries, 'ip_contains' most likely checks whether an IP address is contained within a CIDR block, subnet, or range—a read-only lookup operation. No indication of side effects, data modification, or destructive capability.
From the tool's definition Tool name 'ip_contains' suggests a lookup or query operation. Description is empty, providing no direct evidence of functionality.
Attacks that exploit this kind of access
ip_contains. 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 ip_contains: 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.
ip_contains 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 ip_contains 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 ip_contains. 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.
ip_contains 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.
