THE RISK

Low Risk

Why analyze_layout needs a policy

This tool retrieves and analyzes structural metadata about PDF documents—text blocks, columns, spacing—without modifying, executing code, deleting, or moving money. It is a pure Read operation with minimal blast radius; misuse would only result in unwanted information extraction about document layout, not data corruption or unintended side effects.

From the tool's definition Tool name 'analyze_layout' and description 'Analyze PDF page layout including text blocks, columns, and spacing' indicate passive analysis and extraction of structural information from PDF documents.

POLICY

How to control analyze_layout

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP PDF, and nothing reaches the server without passing your rules. This is the rule we recommend for analyze_layout:

policy.json

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

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