Why countDocuments needs a policy

The tool name 'countDocuments' strongly suggests a read operation that queries document counts. Without a description, confidence is reduced, but the semantic meaning of 'count' indicates retrieval rather than modification, execution, or destructive action. The low severity reflects that even if misused, counting operations typically have minimal blast radius compared to write or execute operations.

From the tool's definition Tool name 'countDocuments' indicates a counting/query operation with no description provided. Based on the name alone, this appears to be a read-only operation that retrieves a count of documents without modifying data.

Documented attack patterns abuse exactly the kind of access countDocuments gives an agent:

How to control countDocuments

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "countDocuments": {}
  }
}

countDocuments is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Amazon Data Processing MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
