THE RISK

Low Risk

Why read-prompt needs a policy

This tool retrieves and displays the contents of an existing prompt file. It performs a query/fetch operation without creating, modifying, deleting, or executing anything. The read-only nature and local file scope result in low severity—misuse would only expose stored prompt content, not cause data loss or code execution.

From the tool's definition Tool name 'read-prompt' and description 'Read a specific prompt file' clearly indicate a retrieval operation with no modification or side effects.

POLICY

How to control read-prompt

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Prompt Manager, and nothing reaches the server without passing your rules. This is the rule we recommend for read-prompt:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "read-prompt": {}
  }
}

read-prompt 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 Prompt Manager — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
