List all Brazilian banks with codes and names
AI agents call get_banks 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 performs a straightforward data retrieval operation—listing banks and their codes. It has no side effects, does not modify data, and retrieves information that is typically public reference data. It falls squarely into the Read category with low severity since misuse would only expose non-sensitive banking reference information.
From the tool's definition Tool name 'get_banks' and description 'List all Brazilian banks with codes and names' indicate a query operation that retrieves and displays publicly available banking reference data without modification or side effects.
Documented attack patterns abuse exactly the kind of access get_banks 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 get_banks:
{
"version": "1",
"default": "deny",
"tools": {
"get_banks": {}
}
}get_banks is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all Brazilian banks with codes and names. 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 get_banks: 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.
get_banks 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_banks 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_banks. 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_banks 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.
