THE RISK

Medium Risk

Why split_pdf needs a policy

Splitting a PDF creates new output files but does not irreversibly destroy the original. It is a Write operation (creates new documents). The original PDF may remain intact, so it's not inherently Destructive. Medium severity because misuse could result in unintended file creation or data fragmentation.

From the tool's definition 'Split PDF into multiple files at specified pages' — creates new files from an existing document

POLICY

How to control split_pdf

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 split_pdf:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "split_pdf": {
      "limits": [
        {
          "counter": "split_pdf_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

split_pdf stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. 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.
