WHAT IT DOES

What issue-close does on Lint

AI agents use issue-close to create or update resources in Lint, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Lint environment.

RISK

Why issue-close is rated Medium

The tool creates or modifies data reversibly by changing an issue's state. While closing an issue has side effects (notifications, workflow changes), it is not destructive (can be undone by reopening) and does not delete data. It falls under Write category rather than Execute because it performs a specific data modification operation rather than executing arbitrary code or commands.

From the tool's definition Tool description states it 'Closes an issue' which modifies the state of an issue from open to closed. This is a reversible write operation - issues can be reopened.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs issue-close safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Lint, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For issue-close, this is the rule to start with:

issue-close Rate-limited

issue-close 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.

          "max": 30,

        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Lint, apply this rule, and every issue-close call is checked against it from then on.
