Conditional Flow based on Email Validity

You can build complex workflows where the next step depends entirely on email quality. If an incoming lead address fails the `check_disposable` tool, you trigger a specific failure path—like notifying an admin—instead of continuing to the billing stage. This allows for graceful handling: if the email is disposable, the workflow stops and logs the reason; otherwise, it proceeds with normal retries.

Pre-send Validation in Automated Campaigns

Before sending a crucial message or initiating a payment sequence, run the Disposable Email Blocker on all collected addresses. This ensures your multi-step workflow never wastes time on bad data. The MCP result feeds directly into Mastra AI's decision engine, guaranteeing that every subsequent step is based on verified information.

Auditable Tool Calls for Compliance

Every single tool execution produces a cryptographically signed audit trail. When you run the Disposable Email Blocker through Mastra AI, you're getting proof that validation happened at a specific point in time. This means your entire operational history is tamper-proof by design.

Setup guide

Set up Disposable Email Blocker MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All Disposable Email Blocker tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "disposable-email-blocker-mcp-client",
  servers: {
    "disposable-email-blocker-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "Disposable Email Blocker Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to Disposable Email Blocker tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent Disposable Email Blocker transactions"
);
console.log(result.text);

No. The check is designed for low latency and integrates seamlessly into exponential backoff logic. It adds minimal overhead while maximizing data quality.

It processes email address strings to validate their domain. The system only uses this string for the check and doesn't store or analyze the content of any corresponding inbox.

Yes. Regex can only check format; our tool actually checks against a maintained database of known disposable domains, offering far superior accuracy.

It's highly reliable. It provides immediate detection on both known spam domains and addresses that fall outside standard corporate formats.
