At BuiltWith Pty Ltd, we’re building the future of web intelligence for developers, data teams, and AI systems. Today we’re excited to introduce three major additions to our API ecosystem: MCP Stream, LLMS.TXT support, and our new WHOAMI endpoints. Together, these features make BuiltWith more powerful, more transparent, and fully ready for AI-first workflows. 🤖

🧠 LLMS.TXT Built for the AI Web

The web is evolving for large language models. Just like robots.txt helped define search engine behavior, llms.txt is emerging as a standard to guide AI systems on how content should be accessed and interpreted.

BuiltWith now has a detailed LLMS.txt for AI and developers to use. Developers can programmatically access this data and integrate it directly into their workflows. You can explore the live interface here: https://api.builtwith.com/llms.txt 📄

🤖 MCP Stream Real-Time AI Integration

MCP Stream introduces Model Context Protocol compatibility to BuiltWith. This enables AI agents and LLM-powered systems to interact with BuiltWith data in real time. Now accessible on the web at https://api.builtwith.com/mcp.

With MCP Stream, AI tools can:

• Access live technology detection data
• Execute structured, context-aware queries
• Integrate directly into agent workflows and automation pipelines

This transforms BuiltWith from a traditional API into a contextual data layer for intelligent systems. ⚡

🧾 WHOAMI Endpoints - Instant Account Intelligence

Our new WHOAMI endpoints provide immediate visibility into your API identity and configuration.

With a simple request, you can retrieve details about your API key, permissions, quota usage, and account context. This makes debugging integrations, validating environments, and building internal dashboards significantly easier.

Whether you’re deploying internal tools, powering SaaS integrations, or embedding BuiltWith into AI agents, WHOAMI gives you clarity and control. 🔎
