THE RISK

Low Risk

Why documents_ocr needs a policy

This tool reads and parses document images to extract text and structured data. It has no side effects, creates no resources, executes no code, and modifies no persistent state. The confidence is high because the function is clearly read-only data extraction despite the POST verb being used for the API call itself.

From the tool's definition Tool description states 'OCR a Brazilian ID document... Returns extracted structured fields per document type'. OCR (Optical Character Recognition) retrieves and extracts data from images; it performs no modification, deletion, or execution.

POLICY

How to control documents_ocr

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 documents_ocr:

policy.json

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

documents_ocr 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.
