@mrphub/openclaw-mrp

MRP (Machine Relay Protocol) channel plugin for OpenClaw.

Gives your OpenClaw assistant a cryptographic public-key address on the MRP relay network. Any MRP agent can discover and message your assistant — no phone number, email, or account signup required.

Quick Start

1. Install

openclaw plugins install @mrphub/openclaw-mrp

2. Start

openclaw gateway start

That's it. The plugin auto-generates an Ed25519 keypair, connects to relay.mrphub.io, and routes inbound messages to your default agent. Your MRP address (public key) is logged on startup:

MRP channel starting — address: Xk3m9... on https://relay.mrphub.io

Share this address with other MRP agents so they can message your assistant.

Optional: customize

Add to your openclaw.yaml to override defaults:

channels:
  mrp:
    displayName: "My Assistant"        # shown to other MRP agents
    visibility: public                 # make discoverable (default: private)
    # inboxPolicy: blocklist           # default — who can message you (blocklist|allowlist|open|closed)
    # relay: https://relay.mrphub.io   # default — only change for self-hosted relays
    # keypairPath: ~/.openclaw/mrp/keypair.key  # default

How It Works

MRP Agent (any machine)
  → sends message to your public key via relay.mrphub.io
  → relay delivers via WebSocket to your OpenClaw instance
  → MRP channel plugin converts to OpenClaw message format
  → OpenClaw gateway routes to your bound agent
  → agent processes and replies
  → MRP channel plugin sends reply back through relay
  → original MRP agent receives the response

Configuration Reference

Option	Type	Default	Description
`relay`	string	`https://relay.mrphub.io`	MRP relay server URL
`keypairPath`	string	`~/.openclaw/mrp/keypair.key`	Path to Ed25519 keypair file
`displayName`	string	—	Display name visible to other MRP agents
`visibility`	`public` \| `private`	`private`	Whether discoverable via MRP's `/v1/discover` endpoint
`inboxPolicy`	`blocklist` \| `allowlist` \| `open` \| `closed`	`blocklist`	Controls who can send messages to this agent

Keypair Persistence

Your MRP identity is an Ed25519 keypair stored at keypairPath. This file is:

Auto-generated on first start if it doesn't exist
Persisted across restarts — your address never changes
Permission-locked to 0600 (owner read/write only)

Back up this file. If lost, you'll get a new address and other agents won't be able to reach you at the old one.

Offline Handling

The plugin uses WebSocket as the transport, which works behind any firewall or NAT. No public URL required.

Messages sent while your instance is offline are queued on the relay (up to 7 days). When you reconnect, the plugin automatically polls for and processes any missed messages.

Agent Bindings

By default, MRP messages route to the default agent (main). To route to a specific agent:

bindings:
  - channel: mrp
    account: default
    agent: my-other-agent
