Get elevation data for locations on the earth
AI agents call maps_elevation to retrieve information from Server Puppeteer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves geographic/elevation data from an external service (likely Google Maps or similar). It has no capability to modify data, execute code, delete resources, or commit financial transactions. The blast radius of misuse is minimal - worst case being excessive API calls or information disclosure of location data, neither of which poses significant risk in typical agent scenarios.
From the tool's definition 'Get elevation data for locations on the earth' - a pure data retrieval operation that queries elevation information without modifying, executing commands, or causing side effects.
Attacks that exploit this kind of access
Get elevation data for locations on the earth. It is categorised as a Read tool in the Server Puppeteer MCP Server, which means it retrieves data without modifying state.
Register the Server Puppeteer MCP server in PolicyLayer and add a rule for maps_elevation: 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 Server Puppeteer. Nothing to install.
maps_elevation 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 maps_elevation 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 maps_elevation. 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.
maps_elevation is provided by the Server Puppeteer MCP server (@hisma/server-puppeteer). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
