CATEGORY-specific POI search near a point — gas stations, truck stops, restaurants, charging stations, etc. Use this when the user has a specific TYPE of place in mind. For broader DISCOVERY (e.g.
AI agents call search_places to retrieve information from ThinAir Geo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only query operation that retrieves point-of-interest data based on location and category filters. It has no side effects on data, does not execute code or commands, and does not create, modify, or delete information. The blast radius of misuse is minimal—an agent could only consume API quota by excessive searches.
From the tool's definition Tool performs 'POI search near a point' with specific place types (gas stations, truck stops, restaurants, charging stations). Description emphasizes search and discovery without mentioning modifications, deletions, or external operations.

CATEGORY-specific POI search near a point — gas stations, truck stops, restaurants, charging stations, etc. Use this when the user has a specific TYPE of place in mind. For broader DISCOVERY (e.g. It is categorised as a Read tool in the ThinAir Geo MCP Server, which means it retrieves data without modifying state.
Register the ThinAir Geo MCP server in PolicyLayer and add a rule for search_places: 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 ThinAir Geo. Nothing to install.
search_places 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 search_places 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 search_places. 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.
search_places is provided by the ThinAir Geo MCP server (thinairtelematics/thinair-geo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
