Implementation Reference
- The main handler function that implements the tool logic by fetching merge request changes from the GitLab API endpoint `/projects/{project_id}/merge_requests/{merge_request_iid}/changes` and formatting the response.
export const getMergeRequestChanges: ToolHandler = async (params, context) => { const { project_id, merge_request_iid } = params.arguments || {}; if (!project_id || !merge_request_iid) { throw new McpError(ErrorCode.InvalidParams, 'project_id and merge_request_iid are required'); } const response = await context.axiosInstance.get( `/projects/${encodeURIComponent(String(project_id))}/merge_requests/${merge_request_iid}/changes` ); return formatResponse(response.data); }; - src/utils/tools-data.ts:106-123 (schema)Defines the tool metadata including name, description, and input schema requiring project_id and merge_request_iid.
