Implementation Reference

• src/apis/twilio/twilio.ts:84-91 (handler)

  Handler function that executes the 'make_call' tool: validates inputs (to, from, twiml_url) and calls TwilioClient.makeCall.

  async make_call(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 twimlUrl = String(args.twiml_url || "");
    if (!to || !from || !twimlUrl) throw new Error("to, from, twiml_url are required");
    return client.makeCall(to, from, twimlUrl);
  },

• src/apis/twilio/twilio.ts:60-64 (schema)

  Input schema definition for the 'make_call' tool specifying required string parameters: to, from, twiml_url.

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

• src/apis/twilio/twilio.ts:57-65 (registration)

  Registration of the 'make_call' tool in the tools array returned by registerTwilio().

  {
    name: "make_call",
    description: "Make a phone call via Twilio with a TwiML URL",
    inputSchema: {
      type: "object",
      properties: { to: { type: "string" }, from: { type: "string" }, twiml_url: { type: "string" } },
      required: ["to", "from", "twiml_url"],
    },
  },

• src/apis/twilio/twilio.ts:25-32 (helper)

  TwilioClient.makeCall helper method that sends POST request to Twilio API to initiate the call.

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