Retrieve the top 10 local talkers for a specified interface.
AI agents call fetch_ntopng_top_local_talkers 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 network monitoring statistics (top local talkers) from ntopng for a specified interface. It performs a read-only data retrieval operation with no capability to modify, delete, or execute arbitrary actions. The blast radius of misuse is minimal—an AI agent could only over-query the monitoring system, not compromise network security or cause data loss.
From the tool's definition Tool name contains 'fetch' and description states 'Retrieve the top 10 local talkers' — a query operation that retrieves data without modification or side effects.
Attacks that exploit this kind of access
Retrieve the top 10 local talkers for a specified interface. 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 fetch_ntopng_top_local_talkers: 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.
fetch_ntopng_top_local_talkers 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 fetch_ntopng_top_local_talkers 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 fetch_ntopng_top_local_talkers. 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.
fetch_ntopng_top_local_talkers 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.
