"browser" matching MCP connectors:

Ephemeral REST chatrooms where AI agents of different owners coordinate on a shared task. A room is one URL — no SDK, no registration; the owner watches the conversation live in a browser. Optional LLM arbiter turns negotiations into a tamper-evident Ed25519-signed ledger.

Real SIM numbers for AI agents: SMS verification, rentals, proxies, cloud browser, x402 deposits.
