Medium Risk

Why linear_create_issue needs a policy

This tool creates new data in the Linear issue tracking system, which is reversible (issues can be deleted or archived). It does not execute arbitrary code, move financial resources, or destructively delete data. The severity is medium because creation of spurious issues could clutter the system and waste team time, but the impact is containable through deletion or archival.

From the tool's definition Tool description states it "Creates a new Linear issue" and "Returns the created issue". This is a creation operation that modifies the Linear system by adding new data (issues/tickets).

How to control linear_create_issue

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "linear_create_issue": {
      "limits": [
        {
          "counter": "linear_create_issue_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

linear_create_issue stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

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