@openclaw/marmot

OpenClaw channel plugin for Marmot Protocol — end-to-end encrypted Nostr messaging via MLS (RFC 9420).

What This Is

A native OpenClaw channel plugin that integrates marmot-cli into OpenClaw's messaging pipeline, following the same architecture as the built-in Signal plugin.

How It Works

Inbound: Polls marmot-cli daemon for new messages every pollIntervalMs, dispatches to agent pipeline
Outbound: Sends messages via marmot-cli daemon JSON-RPC (send_message, 30s timeout for relay publishing)
Daemon: Auto-starts marmot-cli daemon as a subprocess, health-checks via ping RPC, auto-restarts on crash
Sessions: DMs route to agent main session, named groups route to isolated sessions

Prerequisites

OpenClaw installed and running
marmot-cli installed (see below)
A Nostr-compatible MLS messenger such as White Noise on your phone — this is how you chat with your agent from a mobile device

Installing marmot-cli

git clone https://github.com/tkhumush/marmot-cli.git
cd marmot-cli
cargo install --path crates/marmot-agent-cli

Requires Rust 1.75+. Then create and set a default identity:

marmot-cli identity create --name default
marmot-cli identity set-default default

State is stored under ~/.local/share/marmot-cli/ (XDG data dir).

Installation

# Install from ClawHub (once published)
openclaw plugins install clawhub:@openclaw/marmot

# Or from GitHub
openclaw plugins install github:tkhumush/openclaw-marmot

# Restart gateway
openclaw gateway restart

Configuration

Add to your openclaw.json:

{
  channels: {
    marmot: {
      enabled: true,
      cliPath: "marmot-cli",       // path to the marmot-cli binary
      daemonHost: "127.0.0.1",
      daemonPort: 9222,
      autoStart: true,             // auto-spawn daemon if not running
      identityName: "default",     // marmot identity to use
      dmPolicy: "allowlist",       // "open" | "allowlist" — use allowlist until you have a pairing UI
      allowFrom: [
        "npub1..."                 // full bech32 npubs that can message your agent
      ],
      groupPolicy: "open",
      pollIntervalMs: 5000
    }
  }
}

Use dmPolicy: "allowlist" in production. With "open", any Nostr user who obtains your agent's npub can send it messages. Populate allowFrom with the full bech32 npubs of users who should have access.

Setting Up a DM Conversation

MLS requires an explicit invite before two parties can exchange messages. This is a one-time setup per user.

User publishes their KeyPackage — in White Noise: Settings → Identity → Publish KeyPackage. This must be done before the invite, or the invite will time out looking for it on relays.
Create the DM group from marmot-cli (do this from the identity your agent uses):
```
marmot-cli dm create --recipient <user-npub> --publish
```
This creates the MLS group and sends a wrapped welcome invitation to the user's relay inbox. The marmot identity becomes the group admin. Note the group's nostr-id from marmot-cli dm list.
User accepts the invite — the invite appears in White Noise as a new DM conversation. The user taps to accept.
Wait for the first message before replying. Due to how MLS epoch sequencing works, the agent should not send the first message immediately after creating the group. Wait for the user to send a message first; this ensures both parties are at the same epoch before the agent replies. See Known Issues for the technical background.

Logging

The 5-second polling pattern produces [marmot-daemon] agent storage initialized lines in the OpenClaw log every poll cycle. This is normal — it reflects marmot-cli daemon's internal context reload on each receive call. It is not a crash loop.

Brief connect ECONNREFUSED errors during OpenClaw gateway restarts are also expected. The plugin handles these gracefully and resumes polling once the daemon is back up.

Known Issues

First message after invite may be dropped (#3)

When dm create runs, it creates the MLS group (epoch 0) and immediately adds the member (epoch 1) in the same operation. OpenMLS does not retain app-message secrets for the solo epoch 0. If the invited user's first message was encrypted at epoch 0 (before their welcome is processed), decryption fails silently.

Workaround: Have the user send two messages if the first one doesn't appear. The second message will be at epoch 1 and will decrypt correctly.

Sender npub truncated in CLI message output (marmot-cli #1)

marmot-cli dm messages truncates sender npubs in its text output (e.g. npub1abc123 instead of the full 59-character bech32). The plugin works around this by seeding a knownNpubs table from config.allowFrom on every poll cycle, then resolving truncated prefixes before the allowlist check. Once marmot-cli exposes full sender_npub in its RPC message responses, this workaround can be removed.

CLI text-scraping for message polling (#2)

The monitor currently calls marmot-cli dm messages as a subprocess and parses the text output. This is fragile and will be replaced with a native RPC get_messages method once marmot-cli exposes it.

Troubleshooting

No messages arriving from White Noise:

Confirm dmPolicy and allowFrom are set correctly. With allowlist, the sender's full npub must be in allowFrom.
Run marmot-cli receive manually to force a relay fetch.
Check that the DM group exists: marmot-cli dm list.

Agent replies not arriving in White Noise:

send_message publishes to relays before returning and can take up to 30 seconds if damus.io is under load. This is normal.
Check OpenClaw logs for dispatch error (final): marmot RPC send_message timed out — if this appears, the relay was unreachable. The plugin's 30s timeout handles most cases.

Daemon won't start / EADDRINUSE:

A previous daemon process may still be holding port 9222. Kill it: pkill -f 'marmot-cli daemon', then restart OpenClaw.

Invite not appearing in White Noise:

Ensure the user published a KeyPackage before you ran dm create. If the KeyPackage wasn't on the relays at invite time, the welcome was never sent. Delete the group and retry: marmot-cli dm create --recipient <npub> --publish.

Status

Working. Two-way MLS-encrypted messaging confirmed with White Noise iOS (2026-05-13).
