AI agents call geocode_address 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 | — | Optional latitude to bias results. |
lon | number | — | Optional longitude to bias results. |
lang | string | — | Optional language code, for example en. |
limit | integer | — | |
query | string | Yes | Address or place name to geocode. |
Parameters from the server's own tool schema.
This tool retrieves geographic data (coordinates) based on input parameters. It performs a lookup/conversion operation with no data modification, deletion, or execution of arbitrary code. The operation is purely informational and read-only, making it a Read category tool with low severity risk.
From the tool's definition Tool name 'geocode_address' and description 'Convert an address or place name into latitude and longitude coordinates' indicate a data retrieval operation that translates user-provided text into geographic coordinates.
Attacks that exploit this kind of access
Convert an address or place name into latitude and longitude coordinates. It is categorised as a Read tool in the LatLng MCP Server, which means it retrieves data without modifying state.
geocode_address accepts 5 parameters: lat, lon, lang, limit, query. Required: query. 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 geocode_address: 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.
geocode_address 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 geocode_address 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 geocode_address. 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.
geocode_address 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.
geocode_address 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.
