One API for every record.
One MCP server for every agent.

Built for your engineering and data teams: a patient's full, live FHIR record over a single API, and an MCP server that lets your AI agents call clinical tools directly. No glue code, no chart-chasing.

The API

One integration. Every record. In real time.

  • A single REST API — FHIR R4 out of the box
  • Live ADT events the moment they happen
  • One unified, longitudinal patient record
  • SMART on FHIR auth, built in

The MCP Server

Clinical tools your AI agents call natively.

  • Native Model Context Protocol server
  • 40+ typed clinical tools, one call each
  • Agents read records, summarize, find gaps — directly
  • Clients fetch, auth, retries, tracing included

Give your AI agents a clinical brain — in one connection.

Point any agent at the Atticus MCP server and it can reason over a patient's complete, current record the way a clinician would — no custom integration, no scraping, no stale data.

  • Works with any MCP-compatible agent or assistant
  • Every tool returns live, FHIR-grounded data
  • Calls are scoped, audited, and PHI-safe by design

real time

AI that knows each patient — and updates the instant anything changes.

Atticus continuously re-synthesizes each patient's record as new data arrives, so your agents always reason on what's current.

  • Records re-synthesize automatically as new data streams in
  • Grounded in the patient's own clinical evidence
  • Built so agents can act autonomously, around the clock
