Implementation Reference

• src/apis/twilio/twilio.ts:76-83 (handler)

  The asynchronous handler function for the 'send_sms' tool. It validates the input arguments, extracts 'to', 'from', and 'body', and delegates to the Twilio client's sendSms method.

  async send_sms(args: Record<string, unknown>) {
    if (!cfg.twilioAccountSid || !cfg.twilioAuthToken) throw new Error("TWILIO_ACCOUNT_SID/TWILIO_AUTH_TOKEN are not configured");
    const to = String(args.to || "");
    const from = String(args.from || "");
    const body = String(args.body || "");
    if (!to || !from || !body) throw new Error("to, from, body are required");
    return client.sendSms(to, from, body);
  },

• src/apis/twilio/twilio.ts:51-55 (schema)

  The input schema for the 'send_sms' tool, specifying an object with required string properties 'to', 'from', and 'body'.

  inputSchema: {
    type: "object",
    properties: { to: { type: "string" }, from: { type: "string" }, body: { type: "string" } },
    required: ["to", "from", "body"],
  },

• src/apis/twilio/twilio.ts:48-56 (registration)

  The tool registration object for 'send_sms', including name, description, and input schema, within the registerTwilio function's tools array.

  {
    name: "send_sms",
    description: "Send an SMS via Twilio",
    inputSchema: {
      type: "object",
      properties: { to: { type: "string" }, from: { type: "string" }, body: { type: "string" } },
      required: ["to", "from", "body"],
    },
  },

• src/apis/twilio/twilio.ts:16-23 (helper)

  The 'sendSms' helper method in the TwilioClient class that constructs and sends the POST request to Twilio's Messages endpoint.

  sendSms(to: string, from: string, body: string) {
    const form = new URLSearchParams({ To: to, From: from, Body: body });
    return this.request(`/Accounts/${this.accountSid}/Messages.json`, {
      method: "POST",
      headers: { Authorization: `Basic ${this.authHeader}`, "content-type": "application/x-www-form-urlencoded" },
      body: form as any,
    });
  }
