What network_summary does on Nasbridge
AI agents call network_summary to retrieve information from Nasbridge without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why network_summary is rated Low
This tool retrieves and displays existing network configuration data without side effects. It performs a read-only query operation analogous to commands like 'ip addr show' or 'route -n'. No data is modified, deleted, or executed. The blast radius of misuse is minimal — an attacker gains network topology information but cannot alter configurations or trigger actions.
From the tool's definition Tool name 'network_summary' and description 'Get a summary of the network configuration including all interfaces, IPs, default routes, and nameservers' indicates retrieval/query of network information only.
Attacks that exploit this kind of access
The rule that runs network_summary safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Nasbridge, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For network_summary, this is the rule to start with:
network_summary 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 Nasbridge, apply this rule, and every network_summary call is checked against it from then on.
Questions about network_summary
Get a summary of the network configuration including all interfaces, IPs, default routes, and nameservers. It is categorised as a Read tool in the Nasbridge MCP Server, which means it retrieves data without modifying state.
Register the Nasbridge MCP server in PolicyLayer and add a rule for network_summary: 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 Nasbridge. Nothing to install.
network_summary 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 network_summary 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 network_summary. 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.
network_summary is provided by the Nasbridge MCP server (maverick0628/nasbridge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
