Search pickup agencies by service and location
AI agents call search_agencies to retrieve information from Mcp Ap2 without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or searches for pickup agency information based on service and location criteria. It performs a read-only lookup without modifying, deleting, or executing any transactions. Even in the context of an AP2 payment protocol server, this particular tool merely queries agency data and does not commit financial obligations or trigger payment operations.
From the tool's definition Tool name 'search_agencies' and description 'Search pickup agencies by service and location' indicate a query/retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access search_agencies gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for search_agencies:
{
"version": "1",
"default": "deny",
"tools": {
"search_agencies": {}
}
} search_agencies is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search pickup agencies by service and location. It is categorised as a Read tool in the Mcp Ap2 MCP Server, which means it retrieves data without modifying state.
Register the Mcp Ap2 MCP server in PolicyLayer and add a rule for search_agencies: 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 Mcp Ap2. Nothing to install.
search_agencies 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 search_agencies 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 search_agencies. 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.
search_agencies is provided by the Mcp Ap2 MCP server (@codespar/mcp-ap2). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcp Ap2, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
