get_procedure

THE RISK

Low Risk

Why get_procedure needs a policy

This tool retrieves/queries a procedure from the HUDU documentation platform by ID. It performs a read-only operation with no side effects, consistent with the Read category which covers get/fetch/retrieve operations. The low severity reflects the limited blast radius—retrieving a procedure document poses minimal risk even if misused by an AI agent.

From the tool's definition Tool name 'get_procedure' and description 'Get a specific procedure by ID' indicate a retrieval operation with no modification or deletion of data.

POLICY

How to control get_procedure

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

policy.json

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

get_procedure 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 HUDU 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.
