Implementation Reference

• src/index.ts:170-176 (handler)

  The handler function for the 'get_lists' tool in the CallToolRequestSchema handler. It parses the arguments, calls trelloClient.getLists(board_id), and returns the JSON stringified lists.

  case 'get_lists': {
    const { board_id } = (request.params.arguments as { request: GetListsRequest }).request;
    const lists = await this.trelloClient.getLists(board_id);
    return {
      content: [{ type: 'text', text: JSON.stringify(lists, null, 2) }],
    };
  }

• src/index.ts:65-84 (registration)

  Registration of the 'get_lists' tool in the ListToolsRequestSchema handler, including name, description, and inputSchema.

  {
    name: 'get_lists',
    description: 'Get all lists in a board',
    inputSchema: {
      type: 'object',
      properties: {
        request: {
          type: 'object',
          properties: {
            board_id: {
              type: 'string',
              description: 'ID of the board',
            },
          },
          required: ['board_id'],
        },
      },
      required: ['request'],
      title: 'get_listsArguments',
    },

• src/types.ts:45-47 (schema)

  TypeScript interface defining the input parameters for get_lists request.

  export interface GetListsRequest {
    board_id: string;
  }

• src/trello-client.ts:23-28 (helper)

  The TrelloClient method that fetches lists for a board via Trello API, called by the tool handler.

  async getLists(boardId: string): Promise<List[]> {
    const response = await axios.get(
      `${this.baseUrl}/boards/${boardId}/lists?${this.getAuthParams()}`
    );
    return response.data;
  }
