Retrieve statistics for all flow devices.
AI agents call get_ntopng_flow_devices_stats to retrieve information from Mcp Ntopng without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves network monitoring statistics from ntopng without side effects. It performs a read-only query operation to obtain flow device statistics. No data is created, modified, deleted, or any external operations are triggered. The blast radius of misuse is limited to potential information disclosure about network traffic patterns.
From the tool's definition Tool name contains 'get' and description states 'Retrieve statistics' with no mention of modification, deletion, or execution capabilities.
Attacks that exploit this kind of access
Retrieve statistics for all flow devices. It is categorised as a Read tool in the Mcp Ntopng MCP Server, which means it retrieves data without modifying state.
Register the Mcp Ntopng MCP server in PolicyLayer and add a rule for get_ntopng_flow_devices_stats: 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 Mcp Ntopng. Nothing to install.
get_ntopng_flow_devices_stats 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 get_ntopng_flow_devices_stats 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 get_ntopng_flow_devices_stats. 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.
get_ntopng_flow_devices_stats is provided by the Mcp Ntopng MCP server (marcoeg/mcp-server-ntopng). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
