WHAT IT DOES

What list_connectors does on Mcp Ap2

AI agents call list_connectors 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.

THE RISK

Low Risk

Why list_connectors needs a policy

This tool retrieves a static list of supported bank connectors with optional filtering parameters. It has no side effects, does not execute operations, does not modify data, and does not involve financial transactions. The operation is informational only, making it a Read category tool with low severity.

From the tool's definition Tool name 'list_connectors' and description 'Lists supported Brazilian banks' with GET endpoint indicate a read-only query operation with no data modification or execution.

POLICY

How to control list_connectors

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 list_connectors:

policy.json

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

list_connectors 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 Mcp Ap2 — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
