Implementation Reference

• src/tools/boards.ts:36-83 (handler)

  The handler function that executes the logic for the list_boards tool. It calls the Trello client to retrieve boards and formats the output.

  export async function handleListBoards(args: unknown) {
    try {
      const { apiKey, token, filter } = validateListBoards(args);
      const client = new TrelloClient({ apiKey, token });
      
      const response = await client.getMyBoards(filter);
      const boards = response.data;
      
      const summary = `Found ${boards.length} ${filter} board(s)`;
      const boardList = boards.map(board => ({
        id: board.id,
        name: board.name,
        description: board.desc || 'No description',
        url: board.shortUrl,
        lastActivity: board.dateLastActivity,
        closed: board.closed
      }));
      
      return {
        content: [
          {
            type: 'text' as const,
            text: JSON.stringify({
              summary,
              boards: boardList,
              rateLimit: response.rateLimit
            }, null, 2)
          }
        ]
      };
    } catch (error) {
      const errorMessage = error instanceof z.ZodError 
        ? formatValidationError(error)
        : error instanceof Error 
          ? error.message 
          : 'Unknown error occurred';
          
      return {
        content: [
          {
            type: 'text' as const,
            text: `Error listing boards: ${errorMessage}`
          }
        ],
        isError: true
      };
    }
  }
