Why summarize_content needs a policy

This tool extracts and processes information from PDFs to produce summaries and insights. It performs no side effects—no data creation, modification, deletion, code execution, or financial operations. The output is analytical and reversible. This is a classic Read operation: querying/analyzing existing document data.

From the tool's definition Tool name 'summarize_content' and description 'Generate summary and key insights from PDF content' indicate data retrieval and analysis without modification.

POLICY

How to control summarize_content

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 summarize_content:

policy.json

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

summarize_content 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.
