Implementation Reference

• index.ts:177-189 (handler)

  Core handler function in SlackClient that fetches thread replies using Slack's conversations.replies API endpoint.

  async getThreadReplies(channel_id: string, thread_ts: string): Promise<any> {
    const params = new URLSearchParams({
      channel: channel_id,
      ts: thread_ts,
    });
  
    const response = await fetch(
      `https://slack.com/api/conversations.replies?${params}`,
      { headers: this.botHeaders },
    );
  
    return response.json();
  }

• index.ts:322-338 (registration)

  MCP tool registration for 'slack_get_thread_replies', including Zod input schema and thin async handler that calls SlackClient.getThreadReplies.

  server.registerTool(
    "slack_get_thread_replies",
    {
      title: "Get Slack Thread Replies",
      description: "Get all replies in a message thread",
      inputSchema: {
        channel_id: z.string().describe("The ID of the channel containing the thread"),
        thread_ts: z.string().describe("The timestamp of the parent message in the format '1234567890.123456'. Timestamps in the format without the period can be converted by adding the period such that 6 numbers come after it."),
      },
    },
    async ({ channel_id, thread_ts }) => {
      const response = await slackClient.getThreadReplies(channel_id, thread_ts);
      return {
        content: [{ type: "text", text: JSON.stringify(response) }],
      };
    }
  );
