Implementation Reference

• src/index.ts:812-841 (handler)

  The main handler function for the 'get_sequence' tool. It makes an API call to retrieve the specific sequence by ID from Apollo's emailer_campaigns endpoint, formats the details including name, status, creation date, number of steps, and lists each step with type, wait time, and subject.

  private async getSequence(args: any) {
    const response = await this.axiosInstance.get(`/emailer_campaigns/${args.id}`);
    const seq = response.data.emailer_campaign;
  
    let result = `Sequence Details:\n\n`;
    result += `Name: ${seq.name}\n`;
    result += `ID: ${seq.id}\n`;
    result += `Status: ${seq.active ? "Active" : "Inactive"}\n`;
    result += `Created: ${seq.created_at ? new Date(seq.created_at).toLocaleDateString() : "N/A"}\n`;
    result += `Steps: ${seq.num_steps || 0}\n\n`;
  
    if (seq.emailer_steps && seq.emailer_steps.length > 0) {
      result += `Sequence Steps:\n`;
      seq.emailer_steps.forEach((step: any, index: number) => {
        result += `\nStep ${index + 1}:\n`;
        result += `  Type: ${step.type || "Email"}\n`;
        result += `  Wait: ${step.wait_time || 0} days\n`;
        result += `  Subject: ${step.subject || "N/A"}\n`;
      });
    }
  
    return {
      content: [
        {
          type: "text",
          text: result,
        },
      ],
    };
  }

• src/index.ts:311-325 (registration)

  The tool registration in the getTools() array, including name, description, and input schema requiring a 'sequence ID'.

  {
    name: "get_sequence",
    description:
      "Get detailed information about a specific sequence including steps, stats, and settings.",
    inputSchema: {
      type: "object",
      properties: {
        id: {
          type: "string",
          description: "Sequence ID",
        },
      },
      required: ["id"],
    },
  },

• src/index.ts:315-324 (schema)

  The input schema definition for the 'get_sequence' tool, specifying that it requires an object with a mandatory 'id' string parameter representing the Sequence ID.

  inputSchema: {
    type: "object",
    properties: {
      id: {
        type: "string",
        description: "Sequence ID",
      },
    },
    required: ["id"],
  },

• src/index.ts:74-75 (registration)

  The switch case in the CallToolRequestHandler that routes calls to the 'get_sequence' handler function.

  case "get_sequence":
    return await this.getSequence(args);
