Choose Your Setup | Setup | What You Get | Cost | Accounts Needed | |-------|-------------|------|-----------------| | **Baileys only** | WhatsApp messaging | **Free** | None | | **Twilio/Telnyx** | Voice + SMS + WhatsApp | ~$1/mo + usage | Twilio/Telnyx + OpenAI | | **Hybrid** | Voice + SMS (Twilio) + WhatsApp (Baileys) | ~$1/mo + voice usage | Twilio/Telnyx + OpenAI | > **Just want WhatsApp?** Skip to [Option C: Baileys](#option-c-baileys-free-whatsapp) — no accounts, no API keys, completely free. ### 2. Set Up Phone Provider

Option A: Telnyx (Recommended - 50% cheaper)

1. Create account at [portal.telnyx.com](https://portal.telnyx.com) and verify identity 2. [Buy a phone number](https://portal.telnyx.com/#/numbers/buy-numbers) (~$1/month) 3. [Create a Voice API application](https://portal.telnyx.com/#/call-control/applications): - Set webhook URL to your tunnel URL + `/webhook/telnyx/inbound` - Set API version to v2 4. **Enable SMS** on your phone number: - Go to [Messaging](https://portal.telnyx.com/#/messaging) and create a Messaging Profile - Assign your phone number to the profile - Set SMS webhook URL to your tunnel URL + `/webhook/telnyx/sms` 5. **Enable WhatsApp** (optional): - Go to [WhatsApp](https://portal.telnyx.com/#/whatsapp) in portal - Complete WhatsApp Business verification - Set webhook URL to your tunnel URL + `/webhook/telnyx/whatsapp` 6. [Verify your phone number](https://portal.telnyx.com/#/numbers/verified-numbers) for outbound calls 7. Get your **Connection ID** (or Messaging Profile ID) and **API Key**

Option B: Twilio

1. Create account at [twilio.com/console](https://www.twilio.com/console) 2. [Buy a phone number](https://www.twilio.com/console/phone-numbers/incoming) 3. Configure webhooks for your number: - Voice webhook: your tunnel URL + `/webhook/twilio/inbound` - SMS webhook: your tunnel URL + `/webhook/twilio/sms` 4. **Enable WhatsApp** (optional): - Go to [WhatsApp Senders](https://www.twilio.com/console/sms/whatsapp/senders) - Complete WhatsApp Business setup - Set webhook URL to your tunnel URL + `/webhook/twilio/whatsapp` 5. Get your **Account SID** and **Auth Token**

Option C: Baileys (Free WhatsApp — no API provider needed)

Baileys connects directly to WhatsApp's Web protocol via WebSocket. It uses your personal WhatsApp account — no business verification, no API costs, no Twilio/Telnyx required. **How it works:** Same as WhatsApp Web — you link a device by scanning a QR code. **Step 1: Clone and install** ```bash git clone https://github.com/sns45/better-call-claude cd better-call-claude bun install ``` **Step 2: Pair your WhatsApp** ```bash bun run baileys:pair ``` 1. A QR code will appear in your terminal 2. Open WhatsApp on your phone > **Settings > Linked Devices > Link a Device** 3. Scan the QR code 4. Wait for "Paired successfully!" message Your session is saved in `data/baileys-auth/` — you won't need to scan again. **Step 3: Add to Claude Code** (`~/.claude.json` or `~/.claude/settings.json`): ```json { "mcpServers": { "better-call-claude": { "command": "bun", "args": ["run", "/path/to/better-call-claude/src/index.ts"], "env": { "BETTERCALLCLAUDE_WHATSAPP_PROVIDER": "baileys", "BETTERCALLCLAUDE_USER_PHONE_NUMBER": "+1234567890" } } } } ``` That's it! No Tailscale, no Twilio, no OpenAI keys needed. **Step 4: Restart Claude Code and test** Send a WhatsApp message to yourself (or have someone message you) — Baileys receives it and spawns a Claude task. Or ask Claude to send you a WhatsApp: > "Send me a WhatsApp saying hello"

Option D: Hybrid (Twilio/Telnyx voice + Baileys WhatsApp)

Get the best of both worlds: Twilio/Telnyx handles voice calls and SMS, Baileys handles WhatsApp for free. 1. Set up Twilio or Telnyx (Options A/B above) 2. Run `bun run baileys:pair` to pair your WhatsApp 3. Add to your MCP config: ```json { "env": { "BETTERCALLCLAUDE_PHONE_PROVIDER": "twilio", "BETTERCALLCLAUDE_WHATSAPP_PROVIDER": "baileys", "BETTERCALLCLAUDE_PHONE_ACCOUNT_SID": "your-account-sid", "BETTERCALLCLAUDE_PHONE_AUTH_TOKEN": "your-auth-token", "BETTERCALLCLAUDE_PHONE_NUMBER": "+15551234567", "BETTERCALLCLAUDE_USER_PHONE_NUMBER": "+15559876543", "BETTERCALLCLAUDE_OPENAI_API_KEY": "sk-..." } } ``` Voice calls and SMS go through Twilio. WhatsApp goes through Baileys (free).

### 3. Set Up Tailscale Funnel (for webhooks) > **Skip this step** if you're using Baileys-only mode (Option C). Baileys doesn't need webhooks. Tailscale Funnel provides free, stable public URLs for receiving webhooks from your phone provider. > **Why Tailscale?** Free unlimited tunnels, stable URLs (no random subdomains), enterprise-grade security. > > **Path:** Better Call Claude uses `/bcc` path (e.g., `https://your-hostname.ts.net/bcc`) to avoid conflicts with other services. **First-time setup (automated):** When you first start the MCP server, it will guide you through setup: 1. **Install Tailscale** (if not installed): ```bash # macOS brew install tailscale # Linux curl -fsSL https://tailscale.com/install.sh | sh ``` 2. **Authenticate** - The server will auto-run `tailscale up` and open your browser 3. **Enable Funnel** - Visit the URL shown in the terminal to enable Funnel on your tailnet (one-time admin step) That's it! The server handles the rest automatically. ### 4. Install Better Call Claude ```bash # Quick start with bunx (recommended) bunx better-call-claude # Or install globally bun install -g better-call-claude better-call-claude ``` ### 5. Add to Claude Code Add to `~/.claude/settings.json`: ```json { "mcpServers": { "better-call-claude": { "command": "bunx", "args": ["better-call-claude"], "env": { "BETTERCALLCLAUDE_PHONE_PROVIDER": "telnyx", "BETTERCALLCLAUDE_PHONE_ACCOUNT_SID": "your-connection-id", "BETTERCALLCLAUDE_PHONE_AUTH_TOKEN": "your-api-key", "BETTERCALLCLAUDE_PHONE_NUMBER": "+15551234567", "BETTERCALLCLAUDE_USER_PHONE_NUMBER": "+15559876543", "BETTERCALLCLAUDE_OPENAI_API_KEY": "sk-..." } } } } ``` > **Note:** Tailscale setup is automatic on first run. The server will guide you through installation and authentication if needed. Restart Claude Code.

Voice Call Example - Comic Style

#### You → Claude (Inbound Calls) Call your Telnyx/Twilio phone number from your personal phone: > 📱 "Hey Claude, I need you to write unit tests for the payment module. Call me when you're done." Claude will acknowledge and start working. When done, it calls you back. #### Claude → You (Outbound Calls) Claude can initiate calls when it needs your input: > 🤖 "I found 3 different approaches for the caching layer. Want me to explain them so you can choose?" #### Voice Commands During Calls - **"Hang up"** or **"Goodbye"** - End the call - **"Hold on"** - Claude waits for you to continue - **"Go ahead"** - Claude continues with the task - **"Cancel that"** - Abort current action --- ### SMS Messaging #### You → Claude (Inbound SMS) Text your Telnyx/Twilio number: > 💬 "Hey Claude, what's the status of the deployment?" Claude will respond via SMS: > 🤖 "Deployment is 80% complete. Running integration tests now. ETA: 5 minutes." #### Claude → You (Outbound SMS) Claude can send you text updates: > 🤖 "Build failed on line 42 of auth.ts. Reply with 'fix' to auto-fix or 'skip' to continue." --- ### WhatsApp #### You → Claude (Inbound WhatsApp) Send a WhatsApp message to your business number: > 💬 "Show me the error logs from the last hour" Claude responds in WhatsApp: > 🤖 "Found 3 errors:\n1. Connection timeout at 14:32\n2. Auth failure at 14:45\n3. Rate limit at 15:01\n\nWant me to investigate any of these?" #### Claude → You (Outbound WhatsApp) Claude can send rich WhatsApp messages: > 🤖 "Code review complete! Found 2 issues:\n• Line 23: Unused variable\n• Line 67: Missing error handling\n\nReply 'fix' to auto-fix or 'details' for more info." --- ### Cross-Channel Context Start a task on voice and seamlessly continue on WhatsApp - Claude remembers everything.

#### Example Flow 1. **Call Claude:** > 📞 "Hey Claude, run the todo app in dev mode and let's continue on WhatsApp" 2. **Claude starts the app and enters WhatsApp listening mode:** > 🤖 "Todo app running on port 5173. Send me WhatsApp messages for more instructions." 3. **Send WhatsApp message:** > 💬 "Expose it via localtunnel and add the URL to allowed hosts" 4. **Claude responds via WhatsApp:** > 🤖 "Done! Localtunnel URL: https://xyz.loca.lt - I've added it to vite.config.ts allowedHosts" 5. **Continue the conversation:** > 💬 "What's the public IP so I can access it remotely?" > > 🤖 "Your public IP is 203.0.113.42. Access the app at https://xyz.loca.lt" **Key phrases to trigger WhatsApp listening:** - "Continue on WhatsApp" - "Let's talk on WhatsApp" - "Listen for my WhatsApp messages" --- ### WhatsApp Sandbox (Twilio) For testing, you can use Twilio's WhatsApp Sandbox instead of a full WhatsApp Business account. 1. Go to [Twilio Console > Messaging > WhatsApp Sandbox](https://console.twilio.com/us1/develop/sms/try-it-out/whatsapp-learn) 2. Send the join code to the sandbox number (+1 415 523 8886) 3. Set the webhook URL to `{your-tailscale-url}/bcc/webhook/twilio/whatsapp` 4. Add to your config: ```json "BETTERCALLCLAUDE_WHATSAPP_NUMBER": "+14155238886" ``` > **Note:** Sandbox requires re-joining every 72 hours. --- ## How It Works ``` ┌─────────────────┐ ┌──────────────────────────────────┐ │ Your Phone │────────>│ Phone Provider │ │ 📞 Voice │<────────│ (Telnyx/Twilio) │ │ 💬 SMS │ │ │ │ 📱 WhatsApp │ │ • Voice API │ └─────────────────┘ │ • Messaging API │ │ • WhatsApp Business API │ └──────────────┬───────────────────┘ │ webhooks ▼ ┌──────────────────────────────────┐ │ Transport Layer │ │ (Tailscale Funnel) │ └──────────────┬───────────────────┘ │ ▼ ┌─────────────────┐ ┌──────────────────────────────────┐ │ Claude Code │◄──────► │ Better Call Claude MCP Server │ │ (your IDE) │ stdio │ (local, port 3333) │ └─────────────────┘ │ │ │ • Voice handling │ │ • SMS handling │ │ • WhatsApp handling │ │ • Conversation management │ └──────────────┬───────────────────┘ │ ▼ ┌──────────────────────────────────┐ │ OpenAI API │ │ (Whisper STT + TTS) │ │ (Voice calls only) │ └──────────────────────────────────┘ ``` ### Communication Flows **Voice:** 1. **Inbound:** You call → Provider → Webhook → MCP Server → Claude Code 2. **Outbound:** Claude Code → MCP Server → Provider → Your phone rings 3. **Speech:** Your voice → Whisper STT → Text → Claude → TTS → Audio playback **SMS:** 1. **Inbound:** You text → Provider → Webhook → MCP Server → Claude Code 2. **Outbound:** Claude Code → MCP Server → Provider API → SMS delivered **WhatsApp:** 1. **Inbound:** You message → Provider → Webhook → MCP Server → Claude Code 2. **Outbound:** Claude Code → MCP Server → Provider API → WhatsApp delivered --- ## MCP Tools ### Voice Tools #### `receive_inbound_call` Accept and process an incoming call from the user. #### `initiate_call` Start a phone call to the user. ```typescript const { callId, response } = await initiate_call({ message: "Hey! I finished the refactor. What should I work on next?" }); ``` #### `continue_call` Continue an active call with follow-up messages. ```typescript const response = await continue_call({ call_id: callId, message: "Got it. Should I also add the caching layer?" }); ``` #### `speak_to_user` Speak without waiting for a response (for acknowledgments). ```typescript await speak_to_user({ call_id: callId, message: "Let me search for that. One moment..." }); ``` #### `end_call` End an active call. ```typescript await end_call({ call_id: callId, message: "Perfect, I'll get started. Talk soon!" }); ``` #### `get_call_status` Check status of current or recent calls. ```typescript const status = await get_call_status({ call_id: callId }); // { state: "active", duration: 45, transcript: [...] } ``` --- ### Messaging Tools #### `receive_inbound_message` Check for incoming SMS or WhatsApp messages. ```typescript const result = await receive_inbound_message({ channel: "any", // "sms", "whatsapp", or "any" timeout_ms: 5000 // How long to wait }); // { success: true, channel: "sms", conversation_id: "...", message: "Deploy now" } ``` #### `send_sms` Send an SMS message to the user. ```typescript const result = await send_sms({ message: "Build complete! 42 tests passed.", wait_for_reply: true, timeout_ms: 180000 }); // { success: true, conversation_id: "...", reply: "Great, deploy it" } ``` #### `send_whatsapp` Send a WhatsApp message to the user. ```typescript const result = await send_whatsapp({ message: "Found 3 issues in code review:\n• Issue 1\n• Issue 2\n• Issue 3", wait_for_reply: true }); // { success: true, conversation_id: "...", reply: "Fix issue 1 first" } ``` #### `reply_to_conversation` Reply to an existing conversation (works for voice, SMS, or WhatsApp). ```typescript const result = await reply_to_conversation({ conversation_id: "abc-123", message: "Got it, fixing issue 1 now.", wait_for_reply: false }); ``` #### `get_conversation_history` Get the full message history for any conversation. ```typescript const history = await get_conversation_history({ conversation_id: "abc-123" }); // { success: true, channel: "whatsapp", messages: [...], state: "active" } ``` --- ## Costs ### Voice Calls | Service | Cost | |---------|------| | **Telnyx** outbound calls | ~$0.007/min | | **Twilio** outbound calls | ~$0.014/min | | **OpenAI** Whisper (STT) | ~$0.006/min | | **OpenAI** TTS | ~$0.015/1K chars | **Typical voice conversation:** ~$0.03-0.05/minute ### SMS | Service | Cost | |---------|------| | **Telnyx** SMS (US) | ~$0.004/message | | **Twilio** SMS (US) | ~$0.0079/message | **Typical SMS exchange:** ~$0.01-0.02/exchange ### WhatsApp | Service | Cost | |---------|------| | **Baileys** (personal WhatsApp) | **Free** | | **Telnyx** WhatsApp | ~$0.005/message | | **Twilio** WhatsApp | ~$0.005/message + conversation fees | **Typical WhatsApp exchange:** Free (Baileys) or ~$0.01-0.02 (Twilio/Telnyx) ### Infrastructure | Service | Cost | |---------|------| | Phone number | ~$1/month | | **Tailscale Funnel** | Free | --- ## Security Considerations ### Tailscale Funnel Security - Funnel creates a public endpoint but traffic routes through Tailscale's secure network - Integrates with SSO/SCIM for enterprise use - Audit logs available in Tailscale admin console - Webhook signatures verified by default ### General - Phone numbers are never logged - Call transcripts are ephemeral (cleared on restart) - Use environment variables, never hardcode credentials ### Capability attestation This repo ships a [smithmark](https://github.com/smithmark) capability manifest, `smithmark.yaml`, at the repo root. It is a "trust as code" declaration of everything this server touches outside its own process: the network hosts it egresses to (Twilio, Telnyx, OpenAI, WhatsApp/Baileys infrastructure, and, transitively, api.anthropic.com via the spawned `claude` subprocess), the filesystem paths it reads/writes (Baileys auth state, spawn debug logs), the binaries it executes (`claude`, `tailscale`, `which`, `open`, `sudo`), the environment variables it reads, and the secret types it handles (Twilio, Telnyx, and OpenAI API keys). On every GitHub release, `.github/workflows/smithmark-attest.yml` produces a **keyless** Sigstore attestation over the published npm tarball: GitHub's OIDC token is exchanged for a short-lived Fulcio signing certificate, the attestation is signed with it, and the signature is recorded in the public Rekor transparency log. There are no signing keys and no secrets involved. The resulting `smithmark-attestation.sigstore.json` is attached to the GitHub release. Verify a published version with: ```bash smithmark verify better-call-claude@3.1.1 \ --certificate-identity "https://github.com/sns45/better-call-claude/.github/workflows/smithmark-attest.yml@refs/tags/v3.1.1" \ --certificate-oidc-issuer "https://token.actions.githubusercontent.com" ``` (substitute the actual release tag for `v3.1.1`) `smithmark.yaml` is the authoritative declaration of this server's capability surface. `smithmark lint` (and `verify` in strict mode) is deliberately host-unaware: it flags every network/exec/filesystem call site as a generic "undeclared" finding regardless of what the manifest declares at the host level, so it will report advisory findings against any real MCP server that talks to the network. Those findings are expected noise, not a sign the manifest is out of date; the manifest above is the record to trust. --- ## Troubleshooting ### Voice Issues #### Claude doesn't answer calls 1. Check the MCP server is running: `claude --debug` 2. Verify webhook URL is configured in provider dashboard 3. Ensure Tailscale Funnel is active #### Can't make outbound calls 1. Verify `BETTERCALLCLAUDE_USER_PHONE_NUMBER` is correct 2. Check phone number is verified with provider 3. Ensure sufficient balance in provider account #### Audio quality issues 1. Check network connectivity 2. Try different TTS voice: `BETTERCALLCLAUDE_TTS_VOICE=nova` 3. Adjust silence detection: `BETTERCALLCLAUDE_STT_SILENCE_DURATION_MS=1000` ### SMS Issues #### SMS not being received 1. Verify SMS is enabled on your phone number in provider dashboard 2. Check SMS webhook URL is set: `/webhook/telnyx/sms` or `/webhook/twilio/sms` 3. Verify Messaging Profile is assigned to phone number (Telnyx) #### Can't send outbound SMS 1. Check phone number has SMS capability 2. Verify destination number format (E.164: +15551234567) 3. Check provider account balance ### WhatsApp Issues #### WhatsApp messages not received 1. Verify WhatsApp Business is set up in provider portal 2. Check webhook URL: `/webhook/telnyx/whatsapp` or `/webhook/twilio/whatsapp` 3. Ensure WhatsApp Business verification is complete #### Can't send WhatsApp messages 1. User must have messaged you first (WhatsApp 24-hour rule) 2. Check WhatsApp Business approval status 3. Verify message template compliance (for outbound-first messages) ### Baileys Issues #### QR code doesn't appear The QR code cannot display inside the MCP server (stdout is reserved for MCP protocol). Run the pairing script separately: ```bash cd /path/to/better-call-claude bun run baileys:pair ``` Once paired, the session is saved and the MCP server connects automatically. #### "Baileys configured but no session found" Run `bun run baileys:pair` to pair your WhatsApp first, then restart Claude Code. #### WhatsApp logged out Delete the auth directory and re-pair: ```bash rm -rf data/baileys-auth bun run baileys:pair ``` #### Messages not being received 1. Check that Baileys is connected (look for `[Baileys] Connected` in stderr) 2. Ensure messages are from individual chats (group messages are filtered out) 3. Verify the sender is not the linked account itself (own messages are filtered) ### Tailscale Issues #### "Tailscale not running" 1. macOS: Open the Tailscale app from Applications 2. Linux: `sudo systemctl start tailscaled && tailscale up` #### "Funnel not enabled" 1. Visit the URL shown in the terminal to enable Funnel 2. Or go to https://login.tailscale.com/admin/acls and add Funnel capability #### Funnel starts but webhooks don't work 1. Check `tailscale funnel status` shows `/bcc` pointing to your port 2. Verify your phone provider webhook URL matches the Tailscale URL (with `/bcc` path) 3. Test with `curl https://your-hostname.ts.net/bcc/health` --- ## Development ```bash # Clone the repo git clone https://github.com/sns45/better-call-claude cd better-call-claude # Install dependencies bun install # Run in development mode bun run dev ``` ### Testing locally ```bash # Start the MCP server bun run dev # In another terminal, test with MCP inspector npx @anthropics/mcp-inspector ``` --- ## Tech Stack - **Runtime:** [Bun](https://bun.sh) - Fast JavaScript runtime - **Web Framework:** [Hono](https://hono.dev) - Lightweight, fast web framework - **Phone:** [Telnyx](https://telnyx.com) / [Twilio](https://twilio.com) - Telephony APIs - **WhatsApp:** [Baileys](https://github.com/WhiskeySockets/Baileys) - Free WhatsApp Web protocol - **Speech:** [OpenAI Whisper](https://openai.com) - STT/TTS - **Transport:** [Tailscale Funnel](https://tailscale.com/kb/1223/funnel) - Public URL tunneling - **Protocol:** [MCP](https://modelcontextprotocol.io) - Model Context Protocol --- ## Contributing PRs welcome!
