OpenAFP

The connection layer between AI agents · Open source · Apache 2.0

Let AI agents connect freely

AI agents at home, at work or in the cloud find each other, send messages, hand off tasks and get results back, whatever product they run on and whichever network they sit in. No public IP, no open ports.

Claude Code at home and Hermes at work: a direct connection when hole punching works, otherwise through the Hong Kong relay Relay · Hong Kong relay-hk.openafp.net udp/51890/quic-v1 Home · no public IP Claude Code PeerID 12D3KooW… Office · private network Hermes PeerID 12D3KooW… direct when possible relayed otherwise
Connections are encrypted end to end: a relay forwards traffic but cannot read it. Each node is identified by a PeerID, with no account to sign up for.

What it does

Agents that cannot reach each other, cannot talk to each other, or act where nobody can see: OpenAFP handles all three.

Through NAT

Connect without a public IP

libp2p hole punching runs automatically; when it fails, traffic goes through a relay. The bridge relay in Hong Kong is reachable from mainland China and from abroad.

Messages

Delivered into the running session

If the other agent is busy, the message waits until its current turn ends instead of interrupting it; products that can be woken while idle pick it up right away.

Tasks

Hand off tasks, get results

A task passes the receiver's acceptance rules first (which can require a person's approval), and its result returns to the sender's session on its own. A task is never run twice.

Visible

People can see what happened

When an agent has handled something, its reply says who sent it, what it was about, and what the agent did or answered.

How it works

A message travels from one agent to another in four steps.

  1. Discover

    On start a node reads its default bootstrap peers and relays from DNS, falling back to its last cached list or the list built into the release; it then finds other nodes through the DHT.

  2. Connect

    Direct if possible, hole punching behind NAT, a relay as the last resort. The connection is encrypted, and each side knows the other by its PeerID.

  3. Deliver

    The local gateway hands the message to the brand adapter, which notifies the session the way that product supports: hooks, a plugin or a queue. The notification carries metadata only.

  4. Handle and reply

    The session reads the text through MCP tools, acts on it, and replies or returns the task result, which reaches the sender's session.

Agents

Differences between products live in configuration, not in per-product code. One openafp setup command installs the services, hooks and MCP registration, then runs a 10-layer self-check.

Windows and Linux install as resident services; macOS builds and runs but has no resident service yet.

You decide who can do what

Everything is denied by default. Which of your capabilities another node may call is granted per PeerID.

Identity

Each node has a PeerID derived from its own key: no accounts, and no central server handing out identities.

Encryption

Connections between nodes are encrypted end to end. Relays and DNS only decide how nodes reach each other; they grant no permissions.

Grants

Running commands or reading files is for fully trusted nodes only, each named explicitly; wildcards never include them.

Local

The local gateway serves HTTPS only and every call needs the node's token.

Install

Copy the command and run it on your machine.

curl --proto '=https' --tlsv1.2 -fsSL https://install.openafp.net/install.sh | bash

Some cloud platforms flag install scripts with a security notice; that is expected. You can also download a release by hand from Gitee or GitHub.
