GitLab Automation via Rube MCP

Automate GitLab operations including project management, issue tracking, merge request workflows, CI/CD pipeline monitoring, branch management, and user administration through Composio's GitLab toolkit.

Prerequisites

• Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
• Active GitLab connection via RUBE_MANAGE_CONNECTIONS with toolkit gitlab
• Always call RUBE_SEARCH_TOOLS first to get current tool schemas

Setup

Get Rube MCP: Add https://rube.app/mcp as an MCP server in your client configuration. The endpoint alone does not authorize GitLab access. Authenticate the MCP client and connect the intended GitLab account through the returned supported authorization flow.

1. Verify Rube MCP is available by confirming RUBE_SEARCH_TOOLS responds

2. Call RUBE_MANAGE_CONNECTIONS with toolkit gitlab

3. If connection is not ACTIVE, follow the returned auth link to complete GitLab OAuth

4. Confirm connection status shows ACTIVE before running any workflows

Confirm the GitLab instance, account and project before acting. Listing does not authorize issue/project/branch creation, user changes or merge actions; use the user-approved target and operation. Preserve protections, preview destructive changes, and reconcile an uncertain write outcome before retrying. Never send tokens or private repository contents to unrelated services.

Core Workflows

1. Manage Issues

When to use: User wants to create, update, list, or search issues in a GitLab project

Tool sequence:

1. GITLAB_GET_PROJECTS - Find the target project and get its ID [Prerequisite]

2. GITLAB_LIST_PROJECT_ISSUES - List and filter issues for a project [Required]

3. GITLAB_CREATE_PROJECT_ISSUE - Create a new issue [Required for create]

4. GITLAB_UPDATE_PROJECT_ISSUE - Update an existing issue (title, labels, state, assignees) [Required for update]

5. GITLAB_LIST_PROJECT_USERS - Find user IDs for assignment [Optional]

Key parameters:

• id: Project ID (integer) or URL-encoded path (e.g., "my-group/my-project")
• title: Issue title (required for creation)
• description: Issue body text (max 1,048,576 characters)
• labels: Comma-separated label names (e.g., "bug,critical")
• add_labels / remove_labels: Add or remove labels without replacing all
• state: Filter by "all", "opened", or "closed"
• state_event: "close" or "reopen" to change issue state
• assignee_ids: Array of user IDs; use [0] to unassign all
• issue_iid: Internal issue ID within the project (required for updates)
• milestone: Filter by milestone title
• search: Search in title and description
• scope: "created_by_me", "assigned_to_me", or "all"
• page / per_page: Pagination (default per_page: 20)

Pitfalls:

• id accepts either integer project ID or URL-encoded path; wrong IDs yield 4xx errors
• issue_iid is the project-internal ID (shown as #42), different from the global issue ID
• Labels in labels field replace ALL existing labels; use add_labels/remove_labels for incremental changes
• Setting assignee_ids to empty array does NOT unassign; use [0] instead
• updated_at field requires administrator or project/group owner rights

2. Manage Merge Requests

When to use: User wants to list, filter, or review merge requests in a project

Tool sequence:

1. GITLAB_GET_PROJECT - Get project details and verify access [Prerequisite]

2. GITLAB_GET_PROJECT_MERGE_REQUESTS - List and filter merge requests [Required]

3. GITLAB_GET_REPOSITORY_BRANCHES - Verify source/target branches [Optional]

4. GITLAB_LIST_ALL_PROJECT_MEMBERS - Find reviewers/assignees [Optional]

Key parameters:

• id: Project ID or URL-encoded path
• state: "opened", "closed", "locked", "merged", or "all"
• scope: "created_by_me" (default), "assigned_to_me", or "all"
• source_branch / target_branch: Filter by branch names
• author_id / author_username: Filter by MR author
• assignee_id: Filter by assignee (use None for unassigned, Any for assigned)
• reviewer_id / reviewer_username: Filter by reviewer
• labels: Comma-separated label filter
• search: Search in title and description
• wip: "yes" for draft MRs, "no" for non-draft
• order_by: "created_at" (default), "title", "merged_at", "updated_at"
• view: "simple" for minimal fields
• iids[]: Filter by specific MR internal IDs

Pitfalls:

• Default scope is "created_by_me" which limits results; use "all" for complete listings
• author_id and author_username are mutually exclusive
• reviewer_id and reviewer_username are mutually exclusive
• approved filter requires the mr_approved_filter feature flag (disabled by default)
• Large MR histories can be noisy; use filters and moderate per_page values

3. Manage Projects and Repositories

When to use: User wants to list projects, create new projects, or manage branches

Tool sequence:

1. GITLAB_GET_PROJECTS - List all accessible projects with filters [Required]

2. GITLAB_GET_PROJECT - Get detailed info for a specific project [Optional]

3. GITLAB_LIST_USER_PROJECTS - List projects owned by a specific user [Optional]

4. GITLAB_CREATE_PROJECT - Create a new project [Required for create]

5. GITLAB_GET_REPOSITORY_BRANCHES - List branches in a project [Required for branch ops]

6. GITLAB_CREATE_REPOSITORY_BRANCH - Create a new branch [Optional]

7. GITLAB_GET_REPOSITORY_BRANCH - Get details of a specific branch [Optional]

8. GITLAB_LIST_REPOSITORY_COMMITS - View commit history [Optional]

9. GITLAB_GET_PROJECT_LANGUAGES - Get language breakdown [Optional]

Key parameters:

• name / path: Project name and URL-friendly path (both required for creation)
• visibility: "private", "internal", or "public"
• namespace_id: Group or user ID for project placement
• search: Case-insensitive substring search for projects
• membership: true to limit to projects user is a member of
• owned: true to limit to user-owned projects
• project_id: Project ID for branch operations
• branch_name: Name for new branch
• ref: Source branch or commit SHA for new branch creation
• order_by: "id", "name", "path", "created_at", "updated_at", "star_count", "last_activity_at"

Pitfalls:

• GITLAB_GET_PROJECTS pagination is required for complete coverage; stopping at first page misses projects
• Some responses place items under data.details; parse the actual returned list structure
• Most follow-up calls depend on correct project_id; verify with GITLAB_GET_PROJECT first
• Invalid branch_name/ref/sha causes client errors; verify branch existence via GITLAB_GET_REPOSITORY_BRANCHES first
• Both name and path are required for GITLAB_CREATE_PROJECT

4. Monitor CI/CD Pipelines

When to use: User wants to check pipeline status, list jobs, or monitor CI/CD runs

Tool sequence:

1. GITLAB_GET_PROJECT - Verify project access [Prerequisite]

2. GITLAB_LIST_PROJECT_PIPELINES - List pipelines with filters [Required]

3. GITLAB_GET_SINGLE_PIPELINE - Get detailed info for a specific pipeline [Optional]

4. GITLAB_LIST_PIPELINE_JOBS - List jobs within a pipeline [Optional]

Key parameters:

• id: Project ID or URL-encoded path
• status: Filter by "created", "waiting_for_resource", "preparing", "pending", "running", "success", "failed", "canceled", "skipped", "manual", "scheduled"
• scope: "running", "pending", "finished", "branches", "tags"
• ref: Branch or tag name
• sha: Specific commit SHA
• source: Pipeline source (use "parent_pipeline" for child pipelines)
• order_by: "id" (default), "status", "ref", "updated_at", "user_id"
• created_after / created_before: ISO 8601 date filters
• pipeline_id: Specific pipeline ID for job listing
• include_retried: true to include retried jobs (default false)

Pitfalls:

• Large pipeline histories can be noisy; use status, ref, and date filters to narrow results
• Use moderate per_page values to keep output manageable
• Pipeline job scope accepts single status string or array of statuses
• yaml_errors: true returns only pipelines with invalid configurations

5. Manage Users and Members

When to use: User wants to find users, list project members, or check user status

Tool sequence:

1. GITLAB_GET_USERS - Search and list GitLab users [Required]

2. GITLAB_GET_USER - Get details for a specific user by ID [Optional]

3. GITLAB_GET_USERS_ID_STATUS - Get user status message and availability [Optional]
