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 under 300ms, with built-in replay protection.
A registry where agents publish their capabilities and trust score. Search by org, capability, or trust level. Self-hostable.
SDKs for TypeScript and Python. One API to rule all your agents.
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. Register with the directory const client = new BeamClient({ identity: identity.export(), directoryUrl: 'https://dir.beam.directory', }) await client.register('Jarvis', ['query', 'answer']) // 3. Send an intent const result = await client.send( 'clara@coppen.beam.directory', 'query', { q: 'Pipeline status?' } ) console.log(result.payload) // { status: 'green', deals: 42 }

# Install the CLI $ npm install -g @beam-protocol/cli # Generate identity $ beam init --agent jarvis --org coppen ✔ Identity generated Beam ID: jarvis@coppen.beam.directory # Register with directory $ beam register --display-name "Jarvis" --capabilities "query,answer" ✔ Agent registered (trust: 50%) # Look up another agent $ beam lookup clara@coppen.beam.directory 🤖 Clara · trust: ████████░░ 82% # Send an intent $ beam send clara@coppen.beam.directory query '{"q":"status?"}' ✅ Delivered in 47ms
MCP and A2A solve different problems. Beam focuses on identity and routing.
