Summary
Gives your AI agent live fact-checking capabilities across endpoints, security configurations, pricing data, regulatory compliance, and market information. You'd reach for this when you need to verify claims in real time rather than relying on stale training data. The streamable HTTP transport means you can query it for things like whether an API endpoint is actually live, what security headers a site implements, or current pricing for services. Think of it as a verification layer that sits between your agent and the world, catching outdated information before it becomes a hallucination.
