Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| project_id | No | Project identifier (auto-detected if not provided) Type: integer OR string Format: numeric ID or 'namespace/project' Optional: Yes - auto-detects from current git repository Examples: - 12345 (numeric ID) - 'gitlab-org/gitlab' (namespace/project path) - 'my-group/my-subgroup/my-project' (nested groups) Note: If in a git repo with GitLab remote, this can be omitted | |
| mr_iid | Yes | Merge request number (IID - Internal ID) Type: integer Format: Project-specific MR number (without !) Required: Yes Examples: - 456 (for MR !456) - 7890 (for MR !7890) How to find: Look at MR URL or title - URL: https://gitlab.com/group/project/-/merge_requests/456 → use 456 - Title: "Add new feature (!456)" → use 456 Note: This is NOT the global MR ID |
Implementation Reference
- src/mcp_gitlab/tool_handlers.py:356-362 (handler)The main handler function for the tool. It resolves the project ID (auto-detecting from git if not provided), requires the mr_iid parameter, and delegates to the GitLabClient's get_merge_request_approvals method.def handle_get_merge_request_approvals(client: GitLabClient, arguments: Optional[Dict[str, Any]]) -> Dict[str, Any]: """Handle getting merge request approvals""" project_id = require_project_id(client, arguments) mr_iid = require_argument(arguments, "mr_iid") return client.get_merge_request_approvals(project_id, mr_iid)
