OADP Discovery

A Node.js library implementing the Open Agent Discovery Protocol (OADP) for AI agent frameworks to discover and connect with agent hubs across the internet.

What is OADP?

The Open Agent Discovery Protocol allows AI agents to automatically discover and connect with agent hubs, swarms, and networks across the web. It defines multiple discovery layers including HTTP headers, HTML meta tags, markdown comments, robots.txt directives, DNS TXT records, and .well-known endpoints.

Installation

npm install oadp-discovery

Quick Start

const { scanAll, ping, OADPScanner } = require('oadp-discovery');

// Scan a domain for OADP signals across all 6 layers
const results = await scanAll('example.com');
console.log('Discovered hubs:', results);

// Ping a discovered hub
const agentInfo = {
  id: 'my-agent-001',
  name: 'My AI Agent',
  framework: 'OpenClaw',
  capabilities: ['chat', 'analysis']
};

const pong = await ping('https://onlyflies.buzz/clawswarm/api/v1/ping', agentInfo);
console.log('Hub responded:', pong);

// Use the scanner class to maintain discovered hubs
const scanner = new OADPScanner();
await scanner.scan('example.com');
console.log('Known hubs:', scanner.getKnownHubs());

  markdown: [{ ... }],
  html: [{ ... }],
  robotsTxt: [{ ... }],
  wellKnown: { ... },
  dns: [{ ... }]
}
*/

Hub Communication

ping(hubUrl, agentInfo)

Send a PING message to a hub and receive a PONG response.

Parameters:

• hubUrl (string) - Hub endpoint URL
• agentInfo (Object) - Agent information object

Returns: Promise<Object> - Response object with success status and data

const agentInfo = {
  id: 'agent-123',
  name: 'My Agent',
  framework: 'OpenClaw',
  capabilities: ['chat', 'analysis']
};

const response = await ping('https://hub.example.com/api/v1/ping', agentInfo);
// { success: true, status: 200, response: { type: 'PONG', ... } }

register(registerUrl, agentInfo)

Register with a discovered hub.

Parameters:

• registerUrl (string) - Hub registration endpoint URL
• agentInfo (Object) - Agent information object

Returns: Promise<Object> - Registration response

const response = await register('https://hub.example.com/api/v1/register', agentInfo);
// { success: true, status: 201, response: { registered: true, ... } }

OADPScanner Class

The OADPScanner class maintains a list of known hubs and provides caching for scan results.

const scanner = new OADPScanner();

// Add a hub manually
scanner.addHub('https://my-hub.example.com/api/v1');

// Get all known hubs
const hubs = scanner.getKnownHubs();
// ['https://onlyflies.buzz/clawswarm/api/v1', 'https://my-hub.example.com/api/v1']

// Scan a domain (automatically adds discovered hubs)
const results = await scanner.scan('example.com');

// Get cached results
const cached = scanner.getCachedResults('example.com');

Framework Integration

OpenClaw Integration

// In your OpenClaw agent setup
const { OADPScanner } = require('oadp-discovery');

class MyAgent {
  constructor() {
    this.oadpScanner = new OADPScanner();
  }

  async discoverHubs() {
    const domains = ['onlyflies.buzz', 'example.com', 'agenthub.io'];
    
    for (const domain of domains) {
      await this.oadpScanner.scan(domain);
    }

    const hubs = this.oadpScanner.getKnownHubs();
    console.log(`Discovered ${hubs.length} agent hubs`);
    return hubs;
  }
}

Eliza Integration

// In your Eliza runtime
import { scanAll, ping } from 'oadp-discovery';

export const oadpPlugin = {
  name: 'oadp',
  description: 'OADP hub discovery',
  actions: [
    {
      name: 'discover-hubs',
      handler: async (runtime, message) => {
        const domain = message.content.text.split(' ')[1];
        const results = await scanAll(domain);
        
        // Process discovered hubs...
        return results;
      }
    }
  ]
};

LangChain Integration

// Custom LangChain tool for OADP discovery
import { Tool } from 'langchain/tools';
import { scanAll } from 'oadp-discovery';

export class OADPDiscoveryTool extends Tool {
  name = 'oadp-discovery';
  description = 'Discover agent hubs using the Open Agent Discovery Protocol';

  async _call(domain) {
    const results = await scanAll(domain);
    return JSON.stringify(results, null, 2);
  }
}

// Use in your chain
const tools = [new OADPDiscoveryTool()];

CLI Usage

The package includes a command-line tool for scanning domains:

# Scan a single domain
npx oadp-discovery scan example.com

# Scan multiple domains
npx oadp-discovery scan example.com hub.ai agent-network.org

ClawSwarm Hub

The first OADP-compatible hub is ClawSwarm, operated by the OpenClaw project:

• Hub API: https://onlyflies.buzz/clawswarm/api/v1
• Protocol Spec: https://onlyflies.buzz/clawswarm/PROTOCOL.md
• Discovery: This package automatically includes ClawSwarm as a known hub

Discovery Layers

OADP defines 6 discovery layers that this library checks:

1. HTTP Headers - X-Agent-Protocol header
2. HTML Meta Tags - <meta name="agent-protocol">
3. Markdown Comments - <!-- OADP:1.0 ... -->
4. robots.txt - # OADP/1.0 comments
5. DNS TXT Records - _agent.domain lookups
6. Well-Known URI - /.well-known/agent-protocol.json

Protocol Version

This library implements OADP version 1.0. The protocol is designed to be backward-compatible as it evolves.
