THE RISK

Low Risk

Why list-comments needs a policy

This tool retrieves and queries comment data from a JIRA ticket. It performs no creation, modification, deletion, code execution, or financial operations. The action is purely informational with no blast radius if misused by an AI agent—at worst, it exposes comment content that the agent likely already has read access to.

From the tool's definition Tool name 'list-comments' and description 'List comments on a JIRA ticket' indicate retrieval of existing data with no modification or side effects.

POLICY

How to control list-comments

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list-comments": {}
  }
}

list-comments 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 JIRA MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
