Three ways to integrate.

From a one-line embed to a full API integration to Claude Desktop. Pick the path that matches your use case.

Option 1

harness.js embed — one line

The fastest path. Add physician-governed AI to any healthcare website. Adds: Sage AI chat, patient intake, PROM collection, physician connection, ecosystem footer.

<script
  src="https://harnesshealth.ai/harness.js"
  data-npi="[YOUR_NPI_OR_PARTNER_NPI]"
  data-mode="patient"
></script>
Option 2

REST API

For applications that need programmatic access to the attestation engine, NPI registry, or Sage AI. Response includes: AI draft, attestation token (if physician reviewed), physician NPI, timestamp, document hash.

curl -X POST https://solvinghealth.com/api/chat \
  -H "Authorization: Bearer [API_KEY]" \
  -H "Content-Type: application/json" \
  -d '{
    "message": "Patient reports 7/10 knee pain at rest for 3 days.",
    "npi": "[REVIEWING_PHYSICIAN_NPI]",
    "require_attestation": true,
    "specialty": "orthopedic_surgery"
  }'
Option 3

MCP Connector — Claude Desktop

Connect Claude to the full ecosystem. 231 tools across 10 products. Remote MCP — no install, no API key for evaluation, no local process. One click below, or paste the config into your claude_desktop_config.json manually.

Add to Claude Desktop

Requires Claude Desktop v0.8 or later. The button opens Claude Desktop and pre-fills the harnesshealth MCP server — you approve it, and it's live.
