AI agents call find_ev_charging_stations to retrieve information from OpenStreetMap MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about EV charging station locations—a read-only geospatial query with no side effects. It matches the pattern of other discovery tools on the OpenStreetMap MCP server. The empty description lowers confidence slightly, but the tool name and sibling context make misclassification unlikely.
From the tool's definition Tool name 'find_ev_charging_stations' indicates a lookup/search operation for public EV charging infrastructure; sibling tools on this server (find_nearby_places, find_parking_facilities, find_schools_nearby, search_category) are all read-only data retrieval…
Documented attack patterns abuse exactly the kind of access find_ev_charging_stations gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OpenStreetMap MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for find_ev_charging_stations:
{
"version": "1",
"default": "deny",
"tools": {
"find_ev_charging_stations": {}
}
}find_ev_charging_stations is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

find_ev_charging_stations. It is categorised as a Read tool in the OpenStreetMap MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OpenStreetMap MCP Server MCP server in PolicyLayer and add a rule for find_ev_charging_stations: 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 OpenStreetMap MCP Server. Nothing to install.
find_ev_charging_stations 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 find_ev_charging_stations 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 find_ev_charging_stations. 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.
find_ev_charging_stations is provided by the OpenStreetMap MCP Server MCP server (jagan-shanmugam/open-streetmap-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OpenStreetMap MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
