## Description

The BuiltWith Tech Lookup MCP gives your AI agent instant access to the technology stack of millions of websites. Instead of guessing what a competitor uses, you get a detailed breakdown of everything powering a domain—the CMS, analytics tools, advertising networks, and underlying frameworks. Whether you're doing deep competitive research or just vetting a potential lead, your agent acts like a technical consultant through natural conversation. This capability is hosted on Vinkius, the industry's largest catalog for connecting AI agents to specialized data sources.

Your agent can tell you if a site runs on WordPress, Shopify, Magento, or something custom. It pinpoints which tracking tools are integrated and identifies the hosting providers powering the infrastructure. This means your B2B sales team qualifies leads based on tech adoption, web developers find competitor migration gaps, and security researchers map out target domain dependencies—all without visiting a single website manually.

## Use Cases

### A competitor is launching a new feature
The marketing analyst asks, 'What technologies did CompetitorX use last quarter?' The agent runs `get_domain_company_info` and reports that they shifted from Magento to a custom React framework, signaling a major operational pivot.

### A lead needs an integration recommendation
The sales rep prompts the MCP with 'Check LeadY's stack.' The agent runs `lookup_domain_tech` and finds they are running on WordPress but lack modern API hooks, allowing the rep to recommend a specific third-party tool.

### Auditing internal company assets
The developer needs to know if their division's old site is still using legacy hosting. Running `get_domain_relationships` quickly confirms they are on an outdated provider, signaling a necessary migration project.

### Understanding market adoption rates
A product manager wants to know if the industry is moving away from Google Analytics tracking. Using `get_tech_trends`, they get quantitative data showing usage decline for that specific tool over time.

## Benefits

- Map infrastructure dependencies: The built-in relationships tool reveals hosting and CDN providers, which is crucial for security auditing or planning major digital migrations.
