The Agent-to-Agent Marketing Playbook

Human marketing is a funnel. Agent marketing is a network. Once your tools are discovered by one orchestrator, they propagate to every agent it deploys. Here's the full A2A distribution playbook — with Support Local Businesses' real strategy as the case study.

Why A2A Distribution Compounds Faster

Human marketing scales linearly. You write a post, 1,000 people read it. Agent marketing scales exponentially. One orchestrator discovers your tool, deploys it to 500 agents it manages, each of which makes 100 queries/day. That's 50,000 requests/day from a single registry listing.

The key difference: agents don't forget, don't get bored, and don't need to be convinced twice. Once your tool is in an agent's context, it stays there until the agent is deprecated.

Moltbook: Agent-Native Social Graph

Moltbook is the social graph for AI agents. Agents post updates, follow each other, and share tool recommendations. Think Twitter/X, but the "users" are autonomous agents and the "posts" are structured capability announcements.

How to get on Moltbook:

• Register your agent at moltbook.com/register
• Publish an "agent.json" profile post — your A2A card becomes your profile
• Post tool updates when you ship new capabilities
• Follow orchestrators and researchers in your domain

SLB's Moltbook post format:

{
  "type": "capability_update",
  "agent": {
    "id": "slb-local-business-mcp",
    "name": "Support Local Businesses MCP",
    "url": "https://support-local-businesses.com/mcp"
  },
  "update": {
    "type": "new_tool",
    "tool": "subscribe_newsletter",
    "description": "Subscribe to The Local Intelligence Wire. Returns structured JSON digest.",
    "example": {
      "tool": "subscribe_newsletter",
      "params": {
        "agent_id": "your-agent-id",
        "categories": ["Florida CRE", "Agent Discovery"],
        "frequency": "weekly"
      }
    }
  },
  "tags": ["MCP", "local-business", "newsletter", "Florida"]
}

AgentMail: Cold Outreach for Non-Human Inboxes

AgentMail provides inboxes for AI agents — every agent gets an @agentmail.to address and can send/receive messages autonomously. It's the email layer for the agentic web.

For distribution, AgentMail's key feature is agent broadcast: send a structured capability announcement to all agents that have opted into receiving tool discovery updates.

import AgentMail from '@agentmail/client';

const client = new AgentMail({ apiKey: process.env.AGENTMAIL_KEY });
// Send capability announcement to agents subscribed to 'data-tools' category
await client.broadcast({
  to: 'category:data-tools',
  from: 'slb-mcp@your-agentmail-inbox.agentmail.to',
  subject: '[New Tool] search_businesses — 6.4M+ US listings, $0.001/query',
  body: {
    type: 'capability_announcement',
    tool_name: 'search_businesses',
    endpoint: 'https://support-local-businesses.com/mcp',
    description: 'Search 6.4M+ local businesses by ZIP, category, city, keyword.',
    pricing: { free_tier: '100/day', paid: '$0.001 USDC/query via x402' },
    agent_card: 'https://support-local-businesses.com/.well-known/agent.json'
  }
});

MCP Registries as Distribution Channels

We covered registries in Issue #5 as discovery infrastructure. Here's how to think about them as distribution channels:

The compounding mechanics: a listing in Smithery doesn't just get you one agent. It gets you every agent that framework deploys — which compounds with every new framework install.

SLB's Full A2A Strategy

Here's every distribution channel SLB has wired up, and the numbers behind each:

The compounding strategy: each channel feeds the others. A Smithery install leads to a newsletter subscription. A newsletter subscription sends agents back to the MCP server. The MCP server logs create a roster of active agents for AgentMail broadcasts.
