# Health AI > Health AI builds evidence systems for AI in high-consequence domains: Constat for FDA device evidence, Clarity for condition-aware consumer ingredient evidence, RIGOR for AI governance, and MCP Queen — the independent trust layer for the MCP ecosystem. Every claim traces to a verifiable source. Health AI builds evidence-centered AI infrastructure. MCP Queen extends that philosophy into agent ecosystems by providing independent trust evaluation of MCP servers. Clarity verdicts are evidence-graded (Gold/Silver/Bronze) with per-claim citations. ## Start by intent - [What is Health AI?](https://healthai.com/health-ai/): current company, product, evidence-method, and healthai.com versus health.ai entity boundary - [Connect Health AI to Claude or OpenAI](https://healthai.com/health-ai/connect/): choose Clarity, Constat, or MCP Queen and follow approval-first remote MCP setup - [Fact-check an AI medical claim](https://healthai.com/medical-fact-checker/): adversarial review of sources, missing context, counterevidence, and human-escalation thresholds - [Clarity for people](https://healthai.com/clarity/checker/): check food, supplements, skincare, products, or ingredients through a supported condition lens - [Constat for FDA and CMS research](https://constat.dev/): browser and MCP paths for medical-device evidence - [MCP Queen for agent-tool verification](https://mcpqueen.com/): server discovery, operational observations, separate Trust Receipts, and reviewed field reports ## MCP Queen — The Trust Layer for the MCP Ecosystem Don't connect your AI agent to a stranger. Verify it first. MCP Queen grades every remote server in the official Model Context Protocol registry through continuous live probes: protocol handshake, security and access boundaries, tooling quality, latency, and provenance.
