Retrieve metadata and download information for GitLab CI/CD job artifacts to access build outputs, test results, and reports without downloading files directly.
Instructions
Get information about job artifacts Returns: Artifact metadata and download information Use when: Checking build outputs, downloading test results, accessing reports Security: Returns artifact info only (no actual file download for security) Content: Lists available artifacts with sizes and expiration
Example response: { "job_id": 12345, "job_name": "build:production", "artifacts": [ {"filename": "dist.zip", "size": 1024000}, {"filename": "reports/junit.xml", "size": 5120} ], "artifacts_expire_at": "2023-02-01T00:00:00Z", "download_note": "Use GitLab web interface or CLI for actual downloads" }

Implementation Reference
- src/mcp_gitlab/tool_handlers.py:637-643 (handler)The core handler function for the 'gitlab_download_job_artifact' tool. It validates and extracts required parameters (project_id via detection or arg, job_id, optional artifact_path), then delegates execution to the GitLabClient's download_job_artifact method.
def handle_download_job_artifact(client: GitLabClient, arguments: Optional[Dict[str, Any]]) -> Dict[str, Any]: """Handle downloading job artifacts""" project_id = require_project_id(client, arguments) job_id = require_argument(arguments, "job_id") artifact_path = get_argument(arguments, "artifact_path") return client.download_job_artifact(project_id, job_id, artifact_path) - Pydantic/MCP tool schema definition including input validation schema with required job_id (integer), optional project_id (string) and artifact_path (string). Used for tool registration and input validation.
