Get just the timezone for an IP address.
AI agents call get_ip_timezone 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 queries the IPInfo API to retrieve timezone information associated with an IP address. It performs a simple data lookup with no ability to modify, delete, or execute operations. The blast radius of misuse is minimal — an attacker could only map IP addresses to timezones, which is already public geolocation data. No financial, destructive, or code execution capabilities are present.
From the tool's definition Tool name 'get_ip_timezone' and description 'Get just the timezone for an IP address' indicate a retrieval operation with no side effects.

Yes. Add a rate_limit block to the get_ip_timezone 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.
