Implementation Reference

• src/tools/projects.ts:44-66 (handler)

  The handler function for the n8n_list_projects tool that fetches projects from the n8n API.

  async (params: z.infer<typeof ListProjectsSchema>) => {
    const queryParams: Record<string, unknown> = { limit: params.limit };
    if (params.cursor) queryParams.cursor = params.cursor;
    
    const response = await get<N8nPaginatedResponse<N8nProject>>('/projects', queryParams);
    
    const formatted = response.data.map(formatProject).join('\n\n');
    const output = {
      count: response.data.length,
      projects: response.data,
      nextCursor: response.nextCursor
    };
    
    let text = `Found ${response.data.length} project(s):\n\n${formatted}`;
    if (response.nextCursor) {
      text += `\n\n_More results available. Use cursor: ${response.nextCursor}_`;
    }
    
    return {
      content: [{ type: 'text', text }],
      structuredContent: output
    };
  }
