AI agents call pestsentinel_list_zones to retrieve information from Pest Sentinel — AI Pest Risk Intelligence without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though pestsentinel_list_zones only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

List all geographic zones covered by Pest Sentinel's weekly risk scoring. Pest Sentinel currently covers 500+ zones across 12 US states and 7 Canadian provinces. Each zone is a neighborhood or district within a major city. Args: - country (string, optional): Filter by country code — 'US' or 'CA' - province (string, optional): Filter by state/province code (e.g., 'TX', 'FL', 'ON', 'QC') - region (string, optional): Filter by city/region name (e.g., 'Chicago', 'Toronto') - limit (number): Max results to return, 1–200 (default: 50) - offset (number): Pagination offset (default: 0) - response_format ('markdown' | 'json'): Output format (default: 'markdown') Returns: List of zones with id, name, region, province, country, and coordinates. Examples: - "Show me all zones in Texas" → province='TX' - "What zones are covered in Toronto?" → region='Toronto' - "List all US zones" → country='US'. It is categorised as a Read tool in the Pest Sentinel — AI Pest Risk Intelligence MCP Server, which means it retrieves data without modifying state.
