What edit_issue does on Forgejo

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

Why edit_issue needs a policy

Editing an issue creates or modifies data reversibly without deleting it or executing arbitrary code. While it could cause problems if misused (e.g., changing critical issue descriptions), the effect is reversible through further edits.

From the tool's definition Tool name 'edit_issue' and description 'Edit an existing issue' indicate modification of existing data. This is a reversible write operation on issue metadata (title, description, status, assignees, etc.).

Documented attack patterns abuse exactly the kind of access edit_issue gives an agent:

How to control edit_issue

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

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

edit_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 Forgejo — 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.
