Evaluation Path

Fastest reviewer path:

Connect https://mcp.sentinelsignal.io/mcp
Complete WorkOS OAuth through https://auth.sentinelsignal.io/oauth/login if the client requests first-party user auth
Mint a no-signup trial key with POST https://token.sentinelsignal.io/v1/keys/trial if isolated quota is needed without OAuth
Use the prompt examples below or call score_workflow directly

The hosted server also supports public discovery without a user-supplied key so reviewers can validate initialize, tools/list, and prompt metadata before authenticating. For execution, reviewers can use WorkOS OAuth, a dedicated Sentinel API key, or the hosted shared-trial fallback.

Three Example Prompts

Denial queue triage

You are a healthcare revenue-cycle analyst. Use score_workflow with workflow healthcare.denial for this outpatient claim and decide whether it should be routed to manual review before submission. Return the score, confidence, top explanation factors, and a one-sentence queue recommendation.

Payload:
{
  "external_claim_id": "DENIAL-DEMO-1001",
  "service_date": "2026-02-20",
  "provider_id": 1021,
  "payer_id": 44,
  "cpt_code": "99213",
  "icd10_code": "E119",
  "billed_amount": 250.00,
  "place_of_service": "11",
  "network_status": "in_network"
}

Prior-auth completeness check

Use score_workflow with workflow healthcare.prior_auth to evaluate whether this planned procedure is likely to require prior authorization. Then explain what documentation the operator should verify before scheduling.

Payload:
{
  "member_id": "PA-2001",
  "payer_id": 44,
  "cpt_code": "27447",
  "icd10_codes": ["M17.11"],
  "place_of_service": "22",
  "scheduled_service_date": "2026-03-04"
}

Reimbursement variance review

Use score_workflow with workflow healthcare.reimbursement to estimate expected reimbursement for this claim. Compare the expected amount to the billed amount and tell me whether this should be flagged for finance review.

Payload:
{
  "external_claim_id": "REIMB-3001",
  "payer_id": 17,
  "provider_id": 300,
  "cpt_code": "93000",
  "icd10_code": "I10",
  "billed_amount": 180.00,
  "units": 1,
  "place_of_service": "11"
}

Notes for Review

Hosted discovery is public (initialize, tools/list, prompts/list)
Tool execution supports WorkOS OAuth bearer tokens for first-party remote clients
Tool execution supports a user-supplied Sentinel API key for isolated usage
Trial usage is available without signup for evaluation
Privacy, support, and status links are public and stable
