Implementation Reference
- The `execute` method implementing the tool's core logic: resolves project ID, makes POST request to GitLab API to create MR comment, filters response if fields specified, handles errors.
async execute(args: unknown, context: Context<Record<string, unknown> | undefined>) { const typedArgs = args as { projectId: string | number; mergeRequestId: number; comment: string; fields?: string[]; }; const { projectId: projectIdOrName, mergeRequestId, comment, fields } = typedArgs; try { const client = createGitlabClientFromContext(context); const resolvedProjectId = await client.resolveProjectId(projectIdOrName); if (!resolvedProjectId) { throw new Error(`无法解析项目 ID 或名称：${projectIdOrName}`); } const endpoint = `/projects/${encodeURIComponent(String(resolvedProjectId))}/merge_requests/${mergeRequestId}/notes`; const response = await client.apiRequest(endpoint, "POST", undefined, { body: comment }); if (!client.isValidResponse(response)) { throw new Error(`GitLab API error: ${response?.message || 'Unknown error'}`); } if (fields) { const filteredResponse = filterResponseFields(response, fields); return { content: [{ type: "text", text: JSON.stringify(filteredResponse) }] } as ContentResult; } return { content: [{ type: "text", text: JSON.stringify(response) }] } as ContentResult; } catch (error: any) { return { content: [ { type: "text", text: `GitLab MCP 工具调用异常：${error?.message || String(error)}` } ], isError: true }; } } - Zod schema defining the input parameters: projectId (string|number), mergeRequestId (number), comment (string), optional fields (string[]).

fastmcpTools.forEach(tool => { const standardizedName = toolNameMapping[tool.name as keyof typeof toolNameMapping]; if (shouldRegisterTool(standardizedName as GitLabToolName, options.toolFilter)) { // GitLabTool is now fully compatible with FastMCP's base type, can be registered directly server.addTool(tool); } }); - src/gitlab-tools-sdk.ts:64-64 (registration)Tool name mapping from internal name to standardized name used in filtering.
