Summarize/aggregate routes from a list of CIDRs (IPv4/IPv6 collapsed separately).
AI agents call cidr_summarize to retrieve information from Network MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and processes network routing data to produce summarized output. It has no side effects, does not execute code or commands, does not modify infrastructure, and does not move data or funds. It is a read-only analytical utility.
From the tool's definition Tool performs CIDR summarization/aggregation—a pure analytical operation on network addresses. Description indicates it 'summarize/aggregate routes from a list of CIDRs' with no creation, modification, deletion, code execution, or external effects.
Attacks that exploit this kind of access
Summarize/aggregate routes from a list of CIDRs (IPv4/IPv6 collapsed separately). It is categorised as a Read tool in the Network MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Network MCP Server MCP server in PolicyLayer and add a rule for cidr_summarize: 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 Network MCP Server. Nothing to install.
cidr_summarize 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 cidr_summarize 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 cidr_summarize. 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.
cidr_summarize is provided by the Network MCP Server MCP server (labeveryday/network-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
