agentic-mesh

Transport coordination and configuration layer for multi-agent systems over encrypted mesh networks.

Overview

agentic-mesh provides the networking infrastructure for distributed multi-agent systems. It handles encrypted peer-to-peer connectivity, agent protocol integration, message routing, and state synchronization — so agent frameworks can focus on orchestration logic rather than transport concerns.

Used by multi-agent-protocol as the P2P transport layer for MAP clients, agents, and peers.

Key capabilities:

• Pluggable transports — Nebula, Tailscale, and Headscale backends via a unified TransportAdapter interface
• Agent protocol support — Built-in ACP (Agent Control Protocol) and MAP (Multi-Agent Protocol) integration
• Git over mesh — git-remote-mesh:// protocol for repository sync over encrypted tunnels
• CRDT synchronization — Yjs (in-memory) and cr-sqlite (SQLite) sync providers
• Typed messaging — Pub/sub and RPC channels with offline queuing
• Certificate management — Nebula PKI lifecycle, lighthouse management

Installation

npm install agentic-mesh

For Nebula transport, install Nebula:

# macOS
brew install nebula

# Linux
curl -LO https://github.com/slackhq/nebula/releases/latest/download/nebula-linux-amd64.tar.gz
tar xzf nebula-linux-amd64.tar.gz
sudo mv nebula nebula-cert /usr/local/bin/

Quick Start

As a transport layer for MAP

agentic-mesh is used by the multi-agent-protocol SDK to provide encrypted mesh connectivity:

import { ClientConnection } from '@multi-agent-protocol/sdk'

// Connect a MAP client over an encrypted mesh transport
const client = await ClientConnection.connectMesh({
  transport,
  peer: { peerId: 'server', address: '10.0.0.1', port: 4242 },
  localPeerId: 'my-client',
  name: 'MeshClient',
  reconnection: true,
})

// Use the MAP protocol normally
const agents = await client.listAgents()

As a standalone mesh

import { NebulaMesh, YjsSyncProvider, MessageChannel } from 'agentic-mesh'

// Create mesh connection
const mesh = new NebulaMesh({
  peerId: 'alice',
  nebulaIp: '10.42.0.10',
  port: 7946,
  peers: [{ id: 'bob', nebulaIp: '10.42.0.11' }],
})

await mesh.connect()

// Sync state with CRDT
const provider = new YjsSyncProvider(mesh, { namespace: 'my-project' })
await provider.start()

const shared = provider.getMap<string>('config')
shared.set('version', '1.0.0')

// Send typed messages between peers
const channel = mesh.createChannel<MyMessages>('tasks')
await channel.send('bob', 'task:run', { taskId: '123' })
const result = await channel.request('bob', 'task:run', { taskId: '456' })

ACP over mesh

Bridge Agent Control Protocol sessions over the mesh:

import { AcpMeshAdapter, meshStream } from 'agentic-mesh'
import { AgentSideConnection } from '@agentclientprotocol/sdk'

// Create an ACP-compatible stream over mesh
const stream = meshStream(mesh, { peerId: 'client-peer' })
const connection = new AgentSideConnection(
  (conn) => new MyAcpAgent(conn),
  stream
)

Git over mesh

Clone and push repositories over encrypted tunnels:

git clone git-remote-mesh://peer-id/repository

Transport Abstraction

The TransportAdapter interface supports multiple encrypted transport backends:

Transport	Best For	Setup
Nebula	Air-gapped, enterprise, full control	Self-hosted CA + lighthouses
Tailscale	Quick dev/testing, zero-config	Install + login
Headscale	Self-hosted alternative to Tailscale	Self-hosted coordination server

// Nebula transport
const mesh = new NebulaMesh({
  peerId: 'peer-1',
  nebulaIp: '10.42.0.10',
  port: 7946,
  peers: [{ id: 'peer-2', nebulaIp: '10.42.0.11' }],
})

// Transport features are configurable
const mesh = new NebulaMesh({
  // ...
  features: {
    hubElection: true,
    healthMonitoring: 'transport',
    namespaceRegistry: true,
    offlineQueue: true,
  },
})

API Overview

NebulaMesh

Core mesh connectivity:

const mesh = new NebulaMesh(config)

await mesh.connect()
await mesh.disconnect()

mesh.getPeers()           // List connected peers
mesh.getPeer(id)          // Get specific peer
mesh.isHub()              // Check if this node is the hub
mesh.createChannel(name)  // Create message channel

mesh.on('peer:joined', handler)
mesh.on('peer:left', handler)
mesh.on('hub:changed', handler)

AcpMeshAdapter

Bridge ACP protocol over mesh:

const adapter = new AcpMeshAdapter(mesh)
await adapter.start()

adapter.onRequest(async (request, from, respond) => {
  const response = await server.handleRequest(request)
  respond(response)
})

await adapter.request(peerId, acpRequest, timeout)
adapter.broadcast(notification)

MapServer

Multi-Agent Protocol server for agent orchestration:

const mapServer = new MapServer({
  systemId: 'my-system',
  federation: { enabled: true },
})

YjsSyncProvider

CRDT synchronization:

const provider = new YjsSyncProvider(mesh, { namespace: 'project' })
await provider.start()

provider.getMap(name)     // Get Y.Map
provider.getArray(name)   // Get Y.Array
provider.getText(name)    // Get Y.Text
provider.getDoc()         // Get underlying Y.Doc

MessageChannel

Peer-to-peer messaging:

const channel = mesh.createChannel<Messages>('channel-name')

await channel.send(peerId, type, payload)
channel.broadcast(type, payload)
const response = await channel.request(peerId, type, payload, { timeout: 5000 })

channel.on(type, handler)
channel.handle(type, asyncHandler)  // For request/response

CertManager

const certManager = new CertManager({ certsDir: './certs' })
await certManager.initialize()

await certManager.createRootCA({ name, duration, groups })
await certManager.signServerCert({ name, caName, nebulaIp, duration, groups })
