Why edit_issue_comment needs a policy

Editing an issue comment is a Write operation because it modifies data reversibly. A user or AI agent could change the content of a comment, which affects visibility and understanding of issue discussions, but the change can be undone by editing again. This is less severe than Destructive (which would be irreversible deletion) or Execute (which would run code), but more impactful than Read operations.

From the tool's definition Tool description states 'Edit a comment on an issue', which modifies existing data (the comment text) in a reversible manner. The action updates but does not delete or execute code.

POLICY

How to control edit_issue_comment

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_comment:

policy.json

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

edit_issue_comment 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 Forgejo — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about edit_issue_comment

What does the edit_issue_comment tool do? +

Edit a comment on an issue. It is categorised as a Write tool in the Forgejo MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on edit_issue_comment? +

Register the Forgejo MCP server in PolicyLayer and add a rule for edit_issue_comment: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Forgejo. Nothing to install.

What risk level is edit_issue_comment? +

edit_issue_comment is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit edit_issue_comment? +

Yes. Add a rate_limit block to the edit_issue_comment rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block edit_issue_comment completely? +

Set action: deny in the PolicyLayer policy for edit_issue_comment. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides edit_issue_comment? +

edit_issue_comment is provided by the Forgejo MCP server (sqcows/forgejo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Forgejo tool call.

Start from Forgejo, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
