Publish all merge-request draft notes.
AI agents use gitlab_bulk_publish_draft_notes to create or update resources in Gitlab — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Gitlab environment.
Publishing draft notes transitions them from unpublished to published status, making them visible to other users on a merge request. This is a write operation (data state modification) rather than destructive since the action is reversible—published notes can be deleted or modified.
From the tool's definition Tool name 'publish_draft_notes' and description 'Publish all merge-request draft notes' indicate the tool modifies the state of draft notes by publishing them, which is a reversible write operation. Draft notes can be unpublished or deleted after publishing.

PolicyLayer is an MCP gateway — it sits between your AI agents and Gitlab, and nothing reaches the server without passing your rules. This is the rule we recommend for gitlab_bulk_publish_draft_notes:
{
"version": "1",
"default": "deny",
"tools": {
"gitlab_bulk_publish_draft_notes": {
"limits": [
{
"counter": "gitlab_bulk_publish_draft_notes_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}gitlab_bulk_publish_draft_notes 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.

Publish all merge-request draft notes. It is categorised as a Write tool in the Gitlab MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Gitlab MCP server in PolicyLayer and add a rule for gitlab_bulk_publish_draft_notes: 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 Gitlab. Nothing to install.
gitlab_bulk_publish_draft_notes 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 gitlab_bulk_publish_draft_notes 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 gitlab_bulk_publish_draft_notes. 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.
gitlab_bulk_publish_draft_notes is provided by the Gitlab MCP server (mcpland/gitlab-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Gitlab, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
