THE RISK

Low Risk

Why parse_document needs a policy

This tool fetches and reads a remote document (PDF or DOCX), extracting its text content. It has no side effects beyond the network request. Severity is medium because it can fetch arbitrary URLs, potentially accessing sensitive or internal documents, but it only reads data without modifying anything.

POLICY

How to control parse_document

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

policy.json

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

parse_document 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 Web-curl MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Enforce policy on every Web-curl MCP Server tool call.

Start from Web-curl MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
