AgentInterOp

In American healthcare, systems don't talk. Twenty-five to forty minutes on the phone. Forty-plus intake questions. Days waiting on a prior auth. So we built something that does. AgentInterOp. Healthcare interoperability — agent-native. One MCP server, four agents, every open standard that matters. Meet the roster. First, the BCSE Reasoner. USPSTF breast cancer screening eligibility — with constitutional logic. Not just "eligible" or "not." Every answer cites the guideline version and the rule. Second, the Colonoscopy Scheduler. The forty-question intake, the insurance check, the slot search, the booking, the prep instructions — handled. Third, the Provider Finder. SMART Scheduling Links, filtered by specialty, location, insurer, language. Deep-link booking URLs included. And fourth, the CQL Measure Author. HEDIS, eCQM, USPSTF-derived quality measures — drafted. All four are MCP tools. Plug in your client. Call tools-slash-list. There they are. Call the eligibility tool — three hundred milliseconds later: a determination, the guideline, the cited rule, the reasoning, the recommendation. Plus a task ID. Pass it back, and the conversation continues. Cited. Auditable. Reproducible. Now watch what happens to that colonoscopy call. Twenty-five to forty minutes of phone time… becomes one conversation. Intake. Insurance. Slot search. Booking. Prep. Forty minutes on hold becomes one task ID. But the agents don't just talk to clients. They talk to each other. A2A — agent-to-agent. JSON-RPC two-point-oh, over HTTP and SSE. Message send, message stream, tasks get, tasks resubscribe. One agent card at dot-well-known — discoverable by any client, anywhere. And the chart? The agents read it themselves. Don't ask the patient what the chart already knows. Pass the FHIR server, an access token, a patient ID — and the agents fetch Patient, Condition, Procedure, Coverage, Observation. Directly. Just the SMART-on-FHIR scopes you'd expect. No new lock-in. Just the right standards. MCP Streamable HTTP — twenty-twenty-five oh-six eighteen. A2A — zero-point-two-point-nine. FHIR R4. SMART Scheduling Links. MIT licensed. Free. No auth. AgentInterOp.
