linear_removeFromFavorites

THE RISK

Critical Risk

Removing a favorite is a deletion operation that removes an existing association. While it is relatively low impact (favorites can potentially be re-added), the action is a removal/deletion operation, making Destructive the most appropriate category. Severity is medium since misuse would affect the user's favorites list but not core project data.

HOW TO CONTROL LINEAR_REMOVEFROMFAVORITES

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

policy.json

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

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

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