Build conditional workflows using the MCP Server

The `lookup_domain_tech` tool acts as the starting node for your automated sales qualification pipelines. Your Mastra AI agent checks a prospect's website stack and branches its next steps based on the detected software. If the tool finds a specific competitor's framework, the agent triggers an email sequence tailored to that technology. If the lookup fails, Mastra's built-in retry engine handles the API backoff automatically.

Map infrastructure relationships automatically

The `get_domain_relationships` tool exposes tracking IDs, analytics accounts, and shared server footprints across different domains. Mastra AI agents use this data to group related websites together during security audits. You can write workflows that loop through these connected domains to build a complete profile of a company's web presence. Mastra manages the state of these multi-step operations without requiring external databases.

Track technology trends in background steps

The `get_tech_trends` tool provides usage statistics for specific web technologies over time. Mastra AI runs these checks as scheduled cron jobs to alert your team when a technology loses market share. The agent processes the raw trend metrics, compares them to your target thresholds, and fires webhook payloads using this MCP integration.

Setup guide

Set up BuiltWith Tech Lookup 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 BuiltWith Tech Lookup 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: "builtwith-tech-lookup-mcp-client",
  servers: {
    "builtwith-tech-lookup-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

const result = await agent.generate(
  "List recent BuiltWith Tech Lookup transactions"
);
console.log(result.text);
