THE RISK

Medium Risk

Why jira_create_issue_link needs a policy

This tool creates a link (relationship) between two Jira issues, which is a reversible modification of issue state. It does not execute arbitrary code, delete data irreversibly, move money, or read-only retrieve information. The blast radius is medium because malicious link creation could confuse issue tracking, but the effect is easily undone by deleting the link.

From the tool's definition Tool name and description: 'Create a link between two issues' — the word 'Create' and the action of establishing a relationship between issues indicates a write operation that modifies issue metadata reversibly.

POLICY

How to control jira_create_issue_link

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "jira_create_issue_link": {
      "limits": [
        {
          "counter": "jira_create_issue_link_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

jira_create_issue_link 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.

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