Constat — 483 Risk Radar (MCP server)

The MCP server behind Constat — FDA & NHTSA regulatory-risk intelligence for AI agents, over the Model Context Protocol. Live public regulatory data — recalls, adverse events, warning letters, 510(k) premarket evidence, postmarket drift signals, reimbursement pathways, and vehicle safety. Decision support, not regulatory advice.

Endpoint: https://radar.healthai.com/api/mcp
Transport: Streamable HTTP (JSON-RPC 2.0)
Auth: none for the free tier (60 req/min per IP; an optional X-API-Key header raises limits — shared with Clarity MCP, request one at POST https://mcp.healthai.com/register)
Registry: com.healthai/radar (official MCP registry)

This repository is the public listing/reference for the hosted 483 Risk Radar MCP server. The server itself runs at the endpoint above; this repo carries the server.json manifest and .well-known/mcp.json discovery document for registries and crawlers.

Tools

Tool	What it does
`device_risk_lookup`	FDA compliance risk for a device category by 3-letter product code — recalls, MAUDE trend, warning-letter matches, composite score
`device_evidence_lookup`	Parsed 510(k) premarket evidence for an AI/ML device, each field with a verbatim source quote + page
`evidence_search`	Find AI/ML clearances by product code, panel, applicant, clinical data, sensitivity metric, or PCCP
`predicate_chain`	Trace a device's predicate ancestry with each predicate's age at clearance
`evidence_cohort_stats`	Reporting-rate stats across the parsed AI/ML corpus — presence figures with denominators
`device_postmarket_lookup`	Post-clearance intelligence for one device — recalls, MAUDE trend, letter/483 matches, drift signals
`postmarket_search`	Find devices by postmarket criteria — drift signals, recalls in 24mo, rising MAUDE trend
`cohort_postmarket_stats`	Postmarket presence rates across the AI/ML cohort, each with its denominator
`reimbursement_lookup`	Clearance-to-payment pathway by K/DEN or CPT code — NTAP, Cat I/III, CMS rates, HCPCS, LCDs
`reimbursement_search`	Find payment pathways by mechanism, CPT category, NTAP status, applicant
`reimbursement_stats`	Mechanism distribution across the reimbursement corpus with dollar ranges
`vehicle_risk_lookup`	NHTSA safety history by make/model/year — recall campaigns and complaint stats

Quick start

curl -s https://radar.healthai.com/api/mcp \
  -H 'content-type: application/json' \
  -H 'accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call",
       "params":{"name":"device_risk_lookup","arguments":{"product_code":"FRN"}}}'

List tools with {"method":"tools/list"}. Note the Accept header must include text/event-stream (streamable-HTTP requirement).
