  Handler for the 'get_channels' tool: extracts team_id argument, calls client.getChannelsForTeam(teamId), and returns the channels as formatted JSON text.

  case "get_channels": {
    const teamId = args.team_id as string;
    const channels = await client.getChannelsForTeam(teamId);
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify(channels, null, 2),
        },
      ],
    };
  }

    inputSchema: {
      type: "object",
      properties: {
        team_id: {
          type: "string",
          description: "팀 ID",
        },
      },
      required: ["team_id"],
    },
  },
