AI agents call reverse_geocode to retrieve information from LatLng without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
lat | number | Yes | Latitude. |
lon | number | Yes | Longitude. |
lang | string | — | Optional language code, for example en. |
limit | integer | — |
Parameters from the server's own tool schema.
This tool performs a data retrieval operation: it takes coordinate inputs and returns the corresponding address information. This is a query-like geocoding lookup with no side effects, write operations, code execution, or data destruction. The severity is low because misuse would only return geographic information about a location, with minimal blast radius.
From the tool's definition Tool name 'reverse_geocode' and description 'Convert latitude and longitude coordinates into an address' indicate a lookup operation that retrieves geographic data without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
Convert latitude and longitude coordinates into an address. It is categorised as a Read tool in the LatLng MCP Server, which means it retrieves data without modifying state.
reverse_geocode accepts 4 parameters: lat, lon, lang, limit. Required: lat, lon. The full parameter table on this page comes from the server's own tool schema.
Register the LatLng MCP server in PolicyLayer and add a rule for reverse_geocode: 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 LatLng. Nothing to install.
reverse_geocode 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 reverse_geocode 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 reverse_geocode. 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.
reverse_geocode is provided by the LatLng MCP server (https://mcp.latlng.work/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
reverse_geocode is one line of LatLng's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
