Adds, edits, or deletes a comment on a pull request. Returns structured data with the comment URL, operation type, comment ID, and body echo.
AI agents use pr-comment to create or update resources in Make — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Make environment.
This tool modifies external state (GitHub/VCS pull request comments) but the modifications are largely reversible. Adding or editing comments can be undone by subsequent edits or deletions. While deletion of comments is irreversible, the tool's primary framing emphasizes add/edit operations, and comment deletion is a low-impact operation compared to destructive data loss.
From the tool's definition Tool description states it 'Adds, edits, or deletes a comment on a pull request.' The primary operations are reversible modifications (add, edit) with deletion as a secondary capability. Editing and adding comments are classic Write operations.
Documented attack patterns abuse exactly the kind of access pr-comment gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Make, and nothing reaches the server without passing your rules. This is the rule we recommend for pr-comment:
{
"version": "1",
"default": "deny",
"tools": {
"pr-comment": {
"limits": [
{
"counter": "pr-comment_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}pr-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.

Adds, edits, or deletes a comment on a pull request. Returns structured data with the comment URL, operation type, comment ID, and body echo. It is categorised as a Write tool in the Make MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Make MCP server in PolicyLayer and add a rule for pr-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 Make. Nothing to install.
pr-comment is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the pr-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.
Set action: deny in the PolicyLayer policy for pr-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.
pr-comment is provided by the Make MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Make, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
