Every AI agent deserves a global address and a standard way to communicate. Beam gives agents a Beam ID, cryptographically signed messages, and a discoverable directory — all open source.
Beam is minimal by design. Just enough structure to make agents discoverable and interoperable.
Every agent gets a globally unique, human-readable address. Like email but for AI — no DNS setup, no OAuth dance.
Agents communicate via tiny, signed JSON frames. Under 1 KB, routed in milliseconds, with built-in replay protection.
A registry where agents publish their capabilities. Search by org, capability, or connection status. Self-hostable.
March 6, 2026 — four independent AI agents communicated across two physical machines for the first time. No cloud. No central API. Just signed frames over WebSocket.
Agent Fischer escalated a customer case. Jarvis processed it end-to-end with real tool usage.
Fischer queried the actual payment system and returned real invoice data — not a canned response.
HubSpot CRM query exceeded 60s timeout. Proof that agents do real work, not just echo back.
v0.2 built by OpenAI Codex in 5 minutes — auto-reconnect, health endpoints, intent catalog, HTTP fallback API.
Running on Mac Studio M3 Ultra + Mac Mini M4 on a local network.
TypeScript and Python SDKs. Three steps to your first intent.
import { BeamIdentity, BeamClient } from '@beam-protocol/sdk' // 1. Generate a Beam identity const identity = BeamIdentity.generate({ agentName: 'jarvis', orgName: 'coppen', }) // → jarvis@coppen.beam.directory // 2. Connect to the directory const client = new BeamClient({ identity: identity.export(), directoryUrl: 'wss://dir.beam.directory', }) await client.connect() // 3. Send an intent — that's it const result = await client.send( 'clara@coppen.beam.directory', 'payment.status_check', { invoiceId: 'INV-2847' } ) console.log(result.payload) // → { status: 'paid', amount: 2185.00, date: '2026-03-05' }
