MyMedi-AI/mymedi-ai-mcp-server

MCP server for DME billing and medical coding. Connect Claude, Cursor, VS Code or any MCP client to **32 tools** — code lookup across a database of 90K+ ICD-10-CM, CPT and HCPCS codes, DMEPOS fee schedules, Medicare prior-authorization and face-to-face list checks, denial-code guidance and pre-submission claim checks — plus five DME billing prompts and three dataset resources. Six tools work with no API key.
PHI-free by design: the tools take codes, modifiers, dates of service and de-identified text, never patient identifiers. Apart from drawing credits for paid calls, no tool changes anything except buy_credits, which opens a Stripe checkout session (nothing is charged until checkout is completed in the browser).
**Claude (web or desktop) users:** Settings → Connectors → **Add custom connector** → paste https://mymedi-ai.com/mcp-stream. The endpoint is OAuth-protected: Claude registers itself and asks you to sign in to MyMedi-AI once, and the first connector sign-in comes with free starter credits. There is no API key to copy.
Quick Start
Requires Node.js 20 or later.
Install
Leave out --env MCP_API_KEY=… to start with the six free tools. Other clients are under Client setup.
Get an API key (for the paid tools)
Registration is a POST request, not a web page:
Set the returned apiKey as MCP_API_KEY. (MYMEDI_API_KEY, the name the registration response prints, is accepted too; MCP_API_KEY wins when both are set.) A new key comes with free starter credits; the buy_credits tool adds more.
Or try a free endpoint
Returns basic code metadata, rate-limited to 60 requests per hour per IP.
Free tools (no API key)
Install the server without MCP_API_KEY and these work immediately (60 requests per hour per IP):
| Tool | What it does |
|------|--------------|
| pa_required_check | Is a HCPCS code on the CMS Required Prior Authorization List (42 CFR 414.234) on a date of service; phased-in items by state |
| denial_code_info | DME denial code (CARC) explainer — meaning, common causes, fixes, appealability |
| code_lookup_basic | Basic code metadata — code, type, description, category, active status |
| reimbursement_basic | Medicare national PFS payment and DMEPOS fee-schedule ranges (rental/purchase) |
| order_readiness_checklist | Blank DMEPOS pre-delivery checklist — SWO elements, F2F/WOPD, prior authorization (42 CFR 410.38) |
| modifier_advisor | DMEPOS billing-modifier guidance — KX/GA/GY/GZ, RR/NU/UE, capped-rental months, laterality |
The other 26 tools need an API key (or the connector sign-in): 24 are paid per call, and account_status and buy_credits are free but need the key to identify the account.
