Yes. Phone4.ai works with Claude Code, Anthropic's coding agent. Any Claude plan that supports MCP servers will work. We also have an API for other agent frameworks.

Anything it can do in a normal session: web search, file read/write, database queries, send messages, check calendars — all while talking to you on the phone.
