Fetch geographical location and additional info for hosts.
AI agents call get_ntopng_hosts_location 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 retrieves geographical location metadata for hosts from the ntopng network monitoring system. It performs a read-only data retrieval operation with no capability to modify, delete, or execute actions. The low severity reflects the benign nature of accessing location information about network hosts in a monitoring context.
From the tool's definition Tool name contains 'get_' and description states 'Fetch geographical location and additional info for hosts' — these are query operations that retrieve existing data without modification or side effects.

Fetch geographical location and additional info for hosts. 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_hosts_location: 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_hosts_location 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_hosts_location 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_hosts_location. 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_hosts_location 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.
