Implementation Reference

• src/tools/projects.ts:25-41 (handler)

  The ListProjectsHandler class implements the logic to list projects by calling the Harvest API.

  class ListProjectsHandler implements ToolHandler {
    constructor(private readonly config: BaseToolConfig) {}
  
    async execute(args: Record<string, any>): Promise<CallToolResult> {
      try {
        const validatedArgs = validateInput(ProjectQuerySchema, args, 'project query');
        logger.info('Listing projects from Harvest API');
        const projects = await this.config.harvestClient.getProjects(validatedArgs);
        
        return {
          content: [{ type: 'text', text: JSON.stringify(projects, null, 2) }],
        };
      } catch (error) {
        return handleMCPToolError(error, 'list_projects');
      }
    }
  }

• src/tools/projects.ts:206-223 (registration)

  The list_projects tool is registered in the registerProjectTools function, including its input schema and handler mapping.

  {
    tool: {
      name: 'list_projects',
      description: 'Retrieve a list of projects with optional filtering by client, active status, and updated date. Returns paginated results with comprehensive project details.',
      inputSchema: {
        type: 'object',
        properties: {
          is_active: { type: 'boolean', description: 'Filter by active status' },
          client_id: { type: 'number', description: 'Filter by client ID' },
          updated_since: { type: 'string', format: 'date-time', description: 'Filter by projects updated since this timestamp' },
          page: { type: 'number', minimum: 1, description: 'Page number for pagination' },
          per_page: { type: 'number', minimum: 1, maximum: 2000, description: 'Number of projects per page (max 2000)' },
        },
        additionalProperties: false,
      },
    },
    handler: new ListProjectsHandler(config),
  },
