Why bus_get_my_location needs a policy

This tool queries/retrieves the caller's location to enable transit features (finding nearby stops, planning routes). It performs no modifications, deletions, or external execution. The incomplete description reduces confidence slightly, but the tool name and server context (public transit queries) strongly suggest a read-only data retrieval function.

From the tool's definition Tool name 'bus_get_my_location' and description 'Resolve the caller' indicate retrieval of location data. The description is vague ('Resolve the caller'), but given the context of a public transit MCP server and sibling tools that are all Read operations…

POLICY

How to control bus_get_my_location

PolicyLayer is an MCP gateway — it sits between your AI agents and Chelaile, and nothing reaches the server without passing your rules. This is the rule we recommend for bus_get_my_location:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "bus_get_my_location": {}
  }
}

bus_get_my_location is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Chelaile — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about bus_get_my_location

What does the bus_get_my_location tool do? +

Resolve the caller. It is categorised as a Read tool in the Chelaile MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on bus_get_my_location? +

Register the Chelaile MCP server in PolicyLayer and add a rule for bus_get_my_location: 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 Chelaile. Nothing to install.

What risk level is bus_get_my_location? +

bus_get_my_location is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit bus_get_my_location? +

Yes. Add a rate_limit block to the bus_get_my_location 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.

How do I block bus_get_my_location completely? +

Set action: deny in the PolicyLayer policy for bus_get_my_location. 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.

What MCP server provides bus_get_my_location? +

bus_get_my_location is provided by the Chelaile MCP server (peanutsplash/chelaile-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Chelaile tool call.

Start from Chelaile, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
