WHAT IT DOES

What delete_issue does on Task Trellis MCP

AI agents call delete_issue to permanently remove resources in Task Trellis MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

THE RISK

Why delete_issue needs a policy

This tool permanently removes data (issues) from the system in an irreversible manner. Even though there are safeguards against deleting issues with dependencies, the core function is destructive deletion. The high severity reflects the blast radius: deleting the wrong issue could break task workflows and lose information that cannot be recovered.

From the tool's definition Tool description states 'Deletes an issue from the task trellis system' and 'permanent removal' and 'cannot be easily undone'. The safety notes confirm deletion is irreversible and affects related issues.

POLICY

How to control delete_issue

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_issue"
  ]
}

delete_issue disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
