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: on Free, Pro and Max plans, open Customize → Connectors → + Add → Add custom connector, give it a name and the URL https://mymedi-ai.com/mcp-stream, then Add → Connect. On Team and Enterprise plans an Owner adds it once under Organization settings → Connectors → Add → Custom → Web, and members then Connect it from Customize → Connectors. 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

claude mcp add mymedi-ai --env MCP_API_KEY=your-api-key -- npx -y @mymedi-ai/mcp-server

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:

curl -X POST https://mymedi-ai.com/bot-marketplace/register \

-H "Content-Type: application/json" \ -d '{"name": "my-agent"}'

→ { "apiKey": "...", "credits": ..., "quickStart": { ... } }

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

curl "https://mymedi-ai.com/agent/v1/demo?code=99213"

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):

The other 26 tools need an API key (or the connector sign-in): 24 are paid — per call, or per code for code_lookup_batch, code_validate_batch and pa_exposure_report — and account_status and buy_credits are free but need the key to identify the account.

Credits and billing

• The per-tool price list is published as JSON at https://mymedi-ai.com/bot-marketplace/credits/pricing.
• 1 credit = $0.001. Paid tools cost from 1 credit (code_lookup) to 250 credits (compliance_audit) per call; code_lookup_batch, code_validate_batch and pa_exposure_report are priced per code. A failed call is refunded.
• Each successful paid call's result includes a _billing field: { "creditsSpent": …, "creditsRemaining": …, "priceUSD": … }. (Over plain REST, without MCP, the same figures arrive as X-Credits-Spent / X-Credits-Remaining headers.)
• account_status shows the balance and recent transactions. buy_credits returns a Stripe checkout link — $1 buys 1,000 credits, packages run from $1 to $500 — and the credits arrive once checkout is completed.
