AgentInbox MCP

The safe support inbox for AI agents running e-commerce and DTC stores. Give your agent a real customer-support inbox — with a seatbelt.

What is this?

AI agents can write brilliant customer-support replies for your store. What they can't do:

• Hold a persistent inbox that receives email 24/7 while they're offline

• Manage deliverability, DKIM, threading, and deduplication

• Be trusted to hit "send" unsupervised

AgentInbox sells exactly that missing layer:

• Provisioned inboxes — yourbrand@in.agentinbox.dev, forward your support@ address to it

• Structured conversations — inbound email is thread-stripped, deduplicated, and intent-classified (WISMO, refunds, upsell interest, escalation…)

• Guardrailed sending — send_safe_reply blocks false promises, strips non-whitelisted URLs, and queues with a human-like 8–20 min delay

• Two-stage escalation — only verified-genuine escalations reach the human owner

• Upsell engine — ownership-aware offer injection that turns support into revenue (and suppresses offers during refunds/price objections)

This repo contains the open-source MCP server (stdio) and TypeScript SDK. The hosted email infrastructure and guardrails engine run at agentinbox.dev — grab a free API key (1 inbox, 50 replies/month, no card).

      "url": "https://agentinbox.dev/mcp",
      "headers": { "Authorization": "Bearer aik_live_YOUR_KEY" }
    }
  }
}

Local stdio via npx

{
  "mcpServers": {
    "agentinbox": {
      "command": "npx",
      "args": ["-y", "@agentinbox/mcp", "--api-key", "aik_live_YOUR_KEY"]
    }
  }
}

TypeScript SDK

import { AgentInbox } from "@agentinbox/mcp";

const client = new AgentInbox({ apiKey: process.env.AGENTINBOX_API_KEY! });

const { conversations } = await client.listConversations({ status: "open" });
const { conversation, messages } = await client.getConversation(conversations[0].id);

const result = await client.sendSafeReply({
  conversationId: conversation.id,
  body: "Hi Maria, thanks for reaching out! ...",
});

if (result.blocked) {
  console.log("Guardrails blocked it:", result.reason, result.hint);
}
