Campfire SMS
Campfire SMS
Campfire SMS is a hosted, two-way SMS bridge for developers who use AI coding agents. It connects an agent running in a local session—or a configured cloud agent—to a verified phone number, sending task updates and questions to the user’s regular text inbox and passing replies back to the agent. The service supports MCP-compatible clients, with setup instructions for Codex, Claude Code, Cursor, Grok Build, OpenCode, and Grok Bot. Local agents require the computer and session to remain active; configured Grok Bot routines can run in the cloud while the computer is off. Users can receive build or test completion notices, respond to agent questions, and guide ongoing coding work away from the desk. SMS delivery uses a hosted account and message credits; the agent’s own model, tools, and task execution remain in the agent environment.Starting Price: $5 one-time -
