AgentPhone gives AI agents their own phone line. Through this connector, an agent (or you, in Claude) can buy a dedicated US or Canada number on the fly, then send, receive, and reply to messages, and place voice calls, all through tool calls with full conversation context.
Unlike traditional telephony APIs built for one-way alerts and OTP codes, AgentPhone is built for two-way conversation: an agent can read an incoming text thread or handle a live call, understand it, and respond in context, just like a person would. This makes voice and messaging a first-class communication and identity channel for agents, letting them reach customers, coordinate with people, and run calls end to end.
Key capabilities exposed over MCP:
• Phone numbers: buy, list, attach, and manage US and Canada numbers
• Messaging: send and receive with threads, replies, media, and group chats
• Calls: place calls with a built-in AI that holds the conversation, or drive them with your own webhook, plus full transcripts
• Agents: create agents with their own number, voice, greeting, and behavior
• Contacts and usage: manage an address book and track message, call, and number usage
Connect in seconds via OAuth using your AgentPhone account. No API key required in Claude. Sign up free at agentphone.ai.
