# CoAuth

Agent-native prior-authorization cockpit. A clinician and an AI agent complete a
health-insurance prior authorization together on one live page using the WebMCP
standard. The agent fills and checks the payer form via typed tools; the human
keeps clinical judgment and the legally required signature.

> Up to 82% of denied prior authorizations are overturned on appeal - they were
> never clinically wrong, just mis-filed. CoAuth fixes the filing and keeps the
> human in charge.

## WebMCP tools
