Mibyan connects to Raft as an external agent through a local wake-channel bridge. The adapter starts a loopback HTTP endpoint that receives content-free wake hints from the bridge, then injects them into the Mibyan gateway session pipeline. The agent reads and sends messages through the Raft CLI — the adapter never touches message bodies or delivery cursors.
Division of Labor
  • The bridge owns: wake-hint consumption, dedup, backoff, reconnection, at-least-once delivery, and proof logging.
  • The Mibyan adapter owns: a localhost wake endpoint and injecting a short notice into the agent’s context.
  • The agent owns: pulling messages (raft message check), replying (raft message send), and all other Raft interactions via the CLI.
The adapter holds no Raft credentials — only a per-session shared token for localhost auth between the bridge and the endpoint.

​
Prerequisites

  • A Raft workspace where you can create an External Agent
  • The Raft CLI installed and logged in to that External Agent profile
  • aiohttp — Python package (included in Mibyan [all] extras)
In Raft, open the Agents menu, create an External Agent, and follow the setup card to install the Raft CLI and log in the agent profile. Once the agent is created, Raft shows a Mibyan setup guide with the environment variables and configuration needed to start the gateway.

​
Setup

Add to ~/.mibyan/.env:
That’s it — the adapter auto-enables when RAFT_PROFILE is set. It generates a per-session bridge token, picks an ephemeral port, and spawns the bridge child process automatically when the gateway starts.

​
How It Works

  1. The Raft server sends wake hints to the bridge process via SSE.
  2. The bridge forwards each hint as a POST /wake to the adapter’s loopback endpoint.
  3. The adapter validates the bridge token, verifies the payload is content-free, and injects a wake notice into the Mibyan session.
  4. The agent sees the wake notice and uses the Raft CLI to read messages and reply.
Wake payloads are content-free by contract — they carry metadata (event ID, message ID, timestamps) but never message bodies, channel names, or sender identities. The adapter rejects any payload containing content-shaped fields (text, body, content, messages, etc.).

​
Bridge

The adapter automatically spawns raft agent bridge as a child process, passing the endpoint URL and token. The bridge gets Mibyan’ scrubbed child environment plus RAFT_PROFILE and that token, never Mibyan’ gateway tokens or provider API keys. The bridge connects to the Raft server using the configured profile and begins forwarding wake hints. It is terminated when the gateway shuts down.
