Problem
AI agents increasingly need direct communication channels, yet adding a phone number to an agent typically requires stitching together general-purpose telephony APIs, managing separate voice and messaging flows, and building custom speech synthesis and transcription pipelines.
Solution
AgentPhone gives AI agents their own dedicated phone identity by providing US and Canadian numbers through a single API call, with voice and messages unified through one webhook format and handler. Developers reply with plain text and the platform manages speech synthesis, while inbound calls are handled with real-time transcription. The platform includes native MCP server support, Python and Node.js SDKs, and a REST API, with official integrations for LangChain, Google's Agent Development Kit, and Vercel's Chat SDK. Calls and messages can be routed to any MCP-compatible client, including Claude Code, Cursor, OpenClaw, and Windsurf.
Target Audience
Primary customers are developers and teams building AI agents or agent ecosystems who need a simple, unified telephony layer, including those working in Claude Code, Cursor, OpenClaw, Windsurf, or any MCP-compatible environment.
