Get elevation data for locations on the earth
AI agents call maps_elevation to retrieve information from Helm Chart CLI without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool queries elevation data for geographic locations, returning information without side effects, modification of data, or execution of code. This is a straightforward data retrieval operation falling clearly under the Read category. The severity is low because misuse would only result in unnecessary API calls or information disclosure, with no destructive or financial impact.
From the tool's definition Tool description states 'Get elevation data for locations on the earth' — this is a retrieval operation with no modification or execution of external systems.
Attacks that exploit this kind of access
Get elevation data for locations on the earth. It is categorised as a Read tool in the Helm Chart CLI MCP Server, which means it retrieves data without modifying state.
Register the Helm Chart CLI 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 Helm Chart CLI. 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 Helm Chart CLI MCP server (jeff-nasseri/servers). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
