GitLab Merge Request Integration

Manage GitLab Merge Requests using bash scripts. List MRs, read comments, post feedback, and resolve discussions.

How to Use

Call bash scripts directly via the Bash tool. No MCP server required.

Scripts location: ~/.claude/plugins/cache/awesome-agent-toolkit/gitlab-mr/1.2.1/core/scripts/

IMPORTANT: Environment variables must be set. Check with:

echo $GITLAB_HOST_URL $GITLAB_TOKEN $GITLAB_PROJECT_ID

If empty, add them to ~/.claude/settings.json under env:

{
  "env": {
    "GITLAB_HOST_URL": "https://gitlab.com",
    "GITLAB_TOKEN": "glpat-xxxxxxxxxxxx",
    "GITLAB_PROJECT_ID": "12345678"
  }
}

Available Commands

Set PLUGIN_DIR=~/.claude/plugins/cache/awesome-agent-toolkit/gitlab-mr/1.2.1

Posts a comment on a specific line of a file in the MR diff. Requires SHAs from get-mr-diff-versions.sh.

Workflows

1. Review MR Comments

When user asks about MR comments or code review:

1. •Run: bash $PLUGIN_DIR/core/scripts/get-mr-details.sh <iid> for context
2. •Run: bash $PLUGIN_DIR/core/scripts/get-mr-discussions.sh <iid> for threaded comments
3. •Group by: Unresolved (action needed) vs Resolved
4. •Show code context for inline comments

2. Reply to Review Feedback

When user has fixed something and wants to reply:

1. •Get discussion ID from the discussions list
2. •Run: bash $PLUGIN_DIR/core/scripts/reply-to-discussion.sh <mr_iid> "<discussion_id>" "Fixed in commit abc123..."
3. •Optionally resolve: bash $PLUGIN_DIR/core/scripts/resolve-discussion.sh <mr_iid> "<discussion_id>"

3. Post Inline Code Review Comment

When posting a comment on a specific line in the MR diff:

1. •Get diff versions: bash $PLUGIN_DIR/core/scripts/get-mr-diff-versions.sh <mr_iid>
2. •Use the first (latest) version's SHAs (base_commit_sha, head_commit_sha, start_commit_sha)
3. •Post the inline comment:

bash $PLUGIN_DIR/core/scripts/post-mr-diff-comment.sh <mr_iid> '{"body":"Your comment","position":{"position_type":"text","base_sha":"<base_commit_sha>","head_sha":"<head_commit_sha>","start_sha":"<start_commit_sha>","new_path":"path/to/file.js","old_path":"path/to/file.js","new_line":42}}'

• •Use new_line for commenting on added or unchanged lines (new side of the diff)
• •Use old_line for commenting on removed lines (old side of the diff)
• •For unchanged lines, you can provide both new_line and old_line

4. Post Fix Explanation

Template for fix comments:
