RECOMMENDED RULE

The rule that runs apply_diff_patch safely

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

apply_diff_patch Rate-limited

apply_diff_patch 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.

  "tools": {
    "apply_diff_patch": {
      "limits": [
        {
          "counter": "apply_diff_patch_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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