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. No MCP server required.

Scripts location: ~/.agents/skills/gitlab-mr/scripts/

IMPORTANT: Environment variables must be set. Check with:

echo $GITLAB_HOST_URL $GITLAB_TOKEN $GITLAB_PROJECT_ID

If empty, add them to your shell profile (~/.bashrc or ~/.zshrc):

export GITLAB_HOST_URL="https://gitlab.com"
export GITLAB_TOKEN="glpat-xxxxxxxxxxxx"
export GITLAB_PROJECT_ID="12345678"

Available Commands

Set SKILL_DIR=~/.agents/skills/gitlab-mr

List Merge Requests

# List open MRs (default)
bash $SKILL_DIR/scripts/list-mrs.sh

# List merged MRs
bash $SKILL_DIR/scripts/list-mrs.sh merged

# List closed MRs
bash $SKILL_DIR/scripts/list-mrs.sh closed

# List all MRs
bash $SKILL_DIR/scripts/list-mrs.sh all

Get MR Details

bash $SKILL_DIR/scripts/get-mr-details.sh 123

Returns full MR details including description, source/target branches, author.

Get MR Comments

bash $SKILL_DIR/scripts/get-mr-comments.sh 123

Get MR Discussions (Threaded)

bash $SKILL_DIR/scripts/get-mr-discussions.sh 123

Returns threaded discussions with code context. Includes discussion IDs for replies.

Post Comment on MR

bash $SKILL_DIR/scripts/post-mr-comment.sh 123 "Your comment here"

Reply to Discussion

bash $SKILL_DIR/scripts/reply-to-discussion.sh 123 "discussion_id_abc123" "Your reply"

Resolve Discussion

bash $SKILL_DIR/scripts/resolve-discussion.sh 123 "discussion_id_abc123"

Get MR Diff Versions

bash $SKILL_DIR/scripts/get-mr-diff-versions.sh 123

Returns diff version SHAs (base_commit_sha, head_commit_sha, start_commit_sha) needed for posting inline comments.

Post Inline Diff Comment

bash $SKILL_DIR/scripts/post-mr-diff-comment.sh 123 '{"body":"Consider using a constant here","position":{"position_type":"text","base_sha":"abc123","head_sha":"def456","start_sha":"ghi789","new_path":"src/app.js","old_path":"src/app.js","new_line":42}}'

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 $SKILL_DIR/scripts/get-mr-details.sh <iid> for context
2. Run: bash $SKILL_DIR/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 $SKILL_DIR/scripts/reply-to-discussion.sh <mr_iid> "<discussion_id>" "Fixed in commit abc123..."
3. Optionally resolve: bash $SKILL_DIR/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 $SKILL_DIR/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 $SKILL_DIR/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:

Fixed in commit `abc1234`.

**Changes made:**
- Replaced MD5 with bcrypt for password hashing
- Added salt rounds configuration

**Files changed:**
- `src/auth.js` - Implemented bcrypt hashing
- `tests/auth.test.js` - Added security tests

Output Format

Present MRs as a table:

IID	Title	State	Author	Source → Target
!123	Add login feature	opened	@developer	feature/login → main
!124	Fix parser bug	merged	@coder	fix/parser → main

Unresolved Discussions Format

• @reviewer on src/auth.js:45:

  Consider using bcrypt instead of md5

  • Discussion ID: abc123def
