CampfireSMS is a two-way SMS transport between a verified phone number and an AI agent. Enroll at campfiresms.com and verify your phone before connecting. Local Codex and Grok Build use npx -y @campfiresms/setup YOUR_INSTALLATION_CODE (Node.js 18+, Python 3.12+); keep the computer online and the agent running. Hosted MCP at https://api.campfiresms.com/mcp requires Authorization: Bearer ; adding the URL alone is insufficient. Grok Bot can wake through a separately configured webhook routine. The agent supplies its own model and tools; SMS replies steer work and do not replace native approvals. Free verification demo, monthly plan, and one-time message packs. Setup: https://campfiresms.com/install.html.
