get_merge_request_pipeline
Retrieve the latest pipeline data for a GitLab merge request, including job statuses and IDs for accessing detailed logs.
Instructions
Get the last pipeline data for a specific merge request, including all jobs and their statuses. Returns job IDs that can be used with get_job_log to fetch detailed output.

| Name | Required | Description | Default |
|---|---|---|---|
| merge_request_iid | Yes | Internal ID of the merge request |
Implementation Reference
- Primary tool handler: extracts MR IID from args, calls GitLab API for pipeline and jobs, handles errors, and generates detailed Markdown output with pipeline overview, job lists grouped by status (failed first), timings, links, and status explanations.
