Get just the city for an IP address.
AI agents call get_ip_city to retrieve information from IPInfo MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves geolocation data (city information) for a given IP address with no side effects, data modification, or external actions. It is a pure read operation querying an IP intelligence database. The low severity reflects that IP geolocation data is generally public information with minimal blast radius if misused.
From the tool's definition Tool name 'get_ip_city' and description 'Get just the city for an IP address' indicate a simple lookup/retrieval operation. The server description confirms this is part of IP geolocation and lookup tools that 'provide' intelligence without modification.

Get just the city for an IP address. It is categorised as a Read tool in the IPInfo MCP Server MCP Server, which means it retrieves data without modifying state.
Register the IPInfo MCP Server MCP server in PolicyLayer and add a rule for get_ip_city: 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 IPInfo MCP Server. Nothing to install.
get_ip_city 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_ip_city 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_ip_city. 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_ip_city is provided by the IPInfo MCP Server MCP server (nimblebraininc/mcp-ipinfo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
