Retrieve statistics for all sFlow devices.
AI agents call get_ntopng_sflow_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 queries and returns monitoring statistics from ntopng without any side effects. It is a read-only operation that retrieves pre-computed network device statistics. There is no capacity to modify, delete, or trigger external actions.
From the tool's definition Tool name and description indicate retrieval of statistics: 'Retrieve statistics for all sFlow devices.' No modification, deletion, or execution of operations.
Attacks that exploit this kind of access
Retrieve statistics for all sFlow 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_sflow_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_sflow_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_sflow_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_sflow_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_sflow_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.
