Get list of all cities for address selection
AI agents call get_cities to retrieve information from Food402 without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a static list of cities for UI/form population during address selection. It performs a read-only query with no ability to modify data, execute operations, or affect system state. The low severity reflects minimal risk from misuse—an AI agent cannot cause harm by reading a city list.
From the tool's definition Tool name 'get_cities' and description 'Get list of all cities for address selection' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_cities gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Food402, and nothing reaches the server without passing your rules. This is the rule we recommend for get_cities:
{
"version": "1",
"default": "deny",
"tools": {
"get_cities": {}
}
}get_cities is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get list of all cities for address selection. It is categorised as a Read tool in the Food402 MCP Server, which means it retrieves data without modifying state.
Register the Food402 MCP server in PolicyLayer and add a rule for get_cities: 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 Food402. Nothing to install.
get_cities 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 get_cities 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 get_cities. 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.
get_cities is provided by the Food402 MCP server (rersozlu/food402). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Food402, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
