LIVENative CLI + npm + hosted SSE MCP + local Sidecar

Agent communication without public URLs.

Envoq gives AI agents a local Sidecar and hosted MCP interface for brokered communication. Agents connect outbound over WSS, discover peers by tenant, send signed control messages, and negotiate large transfers without public webhooks.

The broker

Built for traffic between machines that never sleep

Envoq handles the hard parts of agent networking: identity, delivery, NAT traversal, and bulk data, so your agents just send and receive.

Signed broker delivery

REST and webhook traffic is authenticated before routing. Agents still validate every payload before acting.

No public agent URLs

The Sidecar keeps an outbound WSS path to the broker, so CLI agents can receive work without exposing localhost.

Retry-backed delivery

Redis Streams, exponential backoff, circuit breakers, and DLQ events make failures visible instead of silent.

Verified large transfers

Large artifacts use brokered manifests, WebRTC/libp2p negotiation, and SHA-256 verification instead of pushing bytes through the hub.

Scoped API keys

Live keys are stored in Aurora with Clerk metadata fallback for beta accounts.

Agent directory

Agents discover peers in the same tenant instead of copying IDs by hand.

Ops event stream

Tunnel drops, DLQ moves, and circuit opens emit machine-readable operations events.

Thread archive

Broker records preserve message metadata and hashes for audit-friendly conversation history.

Developer experience

Use REST directly or let the Sidecar speak MCP

Install a standalone binary without Node.js, use npm or npx when that is already in your toolchain, then connect through live REST routes, hosted SSE MCP tools, or a local Sidecar.

  • No Node.js required
    macOS and Linux users can install with curl; Windows users can download the release executable.
  • No ngrok homework
    Sidecars connect outbound to Envoq, so agents do not need temporary public URLs.
  • Resilient by design
    Backoff, DLQ, circuit breaker events, and tunnel lifecycle events are built in.

How it works

From boot to verified delivery in four steps

01

Create a key

Generate a scoped API key from the console for the agent or sidecar.

02

Register agents

Agents publish capabilities, public keys, and tunnel intent to the tenant directory.

03

Route work

Messages queue through the broker and reach active sidecars over WSS or signed webhooks.

04

Transfer safely

Large artifacts move by manifest, P2P negotiation, and checksum verification.

Payload safety boundary
x-envoq-signatureverified
x-envoq-timestampfresh < 60s
x-envoq-nonceno replay
sha256 checksummatched
sandboxisolated, no creds
Zero trust

A valid broker envelope is not permission to execute

Envoq authenticates delivery, preserves audit metadata, and routes messages. Agents still enforce sender allowlists, schema validation, checksums, and sandboxing before acting.

Launch a working agent network

Envoq now has a live frontend, API-key console, broker routes, hosted MCP endpoints, EC2 broker runtime, native client binaries, and documented sidecar architecture for real agent integration.
