What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

lookup_codes
Checks codes against the current official releases, which change every year, and reports whether each is valid, billable or terminated today. Returns the official descriptor for ICD-10-CM diagnosis codes, HCPCS Level II service/supply/drug codes and HCPCS modifiers found on an Ex
search_codes
Finds ICD-10-CM diagnosis codes and HCPCS Level II service, supply and drug codes whose official description matches words from a statement (everyday wording such as "flu shot" or "x-ray" is translated to the clinical terms), or whose code starts with the given characters. Use it
explain_insurance_term
Returns KeepMD's plain-language definition, a worked example and related terms for an insurance or medical-billing term from its glossary (allowed amount, deductible, coinsurance, balance billing, CO/PR group codes, No Surprises Act, observation status and about 110 more). Use it
check_eob_math
Recomputes one EOB line or claim total from the printed amounts (billed, allowed, plan paid, deductible, copay, coinsurance, non-covered, patient responsibility) and reports the contractual adjustment, the expected patient responsibility and plan payment, and any discrepancy such
get_eob_reading_guide
Returns KeepMD's step-by-step guide, red flags and links to official consumer resources for reading an Explanation of Benefits (overview), resolving a bill that looks wrong (dispute), appealing a denial (appeal), or the handful of terms that drive the arithmetic (glossary). Use i

Common questions

Is KeepMD MCP for EOB Decoder safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.3) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

KeepMD MCP for EOB Decoder

A read-only Model Context Protocol server that helps an AI assistant read a medical Explanation of Benefits (EOB), Medicare Summary Notice or itemized bill. It is the same job the KeepMD EOB Decoder browser extensions do, exposed to Claude, ChatGPT, Cursor and any other MCP client.

Endpoint: https://mcp.keepmd.org/eob (Streamable HTTP, no authentication) Documentation: https://keepmd.org/mcp-eob-decoder/ Publisher: KeepMD (VertexMD, Inc.) · support@keepmd.org

In plain English: you paste or describe an EOB or bill to Claude, ChatGPT or another assistant, and the assistant uses this server to say what each code means, what the insurance words mean, whether the amounts add up, and what to do next. The server only ever sees codes, words and dollar figures.

What it does

Tool	Purpose
`lookup_codes`	Official descriptors for ICD-10-CM diagnosis codes, HCPCS Level II service/supply/drug codes and HCPCS modifiers, with chapter, plain-language notes and licensing notices for CPT, dental, NDC and X12 remark codes (recognized, not described). Up to 50 codes per call.
`search_codes`	Find ICD-10-CM or HCPCS Level II codes from words in a description, or by code prefix.
`explain_insurance_term`	~115 insurance and billing terms (allowed amount, coinsurance, CO/PR group codes, No Surprises Act, observation status…) with examples and related terms.
`check_eob_math`	Recomputes one service line or claim total from the printed amounts and flags balance billing, mismatched totals and impossible cost sharing.
`get_eob_reading_guide`	Step-by-step guide to reading an EOB, disputing a bill, or appealing a denial, with links to official consumer resources.

Plus the decode_eob prompt and two resources (keepmd://mcp-eob-decoder/glossary, keepmd://mcp-eob-decoder/manifest).

Every tool carries readOnlyHint: true and openWorldHint: false. Every clinical or financial payload carries a disclaimer field: general billing and coding reference, not medical, legal or financial advice.

Privacy

The server has no storage and no accounts. Tools accept codes, terms and dollar amounts only; no schema takes a name, date of birth, member ID, claim number or statement text. Tool arguments are never logged. Full policy: https://keepmd.org/privacy/mcp-eob-decoder/.

Set	Release	License
ICD-10-CM	FY2027 (effective 2026-10-01), NCHS/CMS	Public domain

Use it

Claude (claude.ai → Settings → Connectors → Add custom connector): https://mcp.keepmd.org/eob Claude Code: claude mcp add --transport http keepmd-mcp-eob-decoder https://mcp.keepmd.org/eob Cursor / VS Code / other clients:

{ "mcpServers": { "keepmd-mcp-eob-decoder": { "type": "http", "url": "https://mcp.keepmd.org/eob" } } }

ChatGPT: install from the app directory once listed (see chatgpt/). Gemini CLI: gemini extensions install https://github.com/keepmd-medical/keepmd-mcp-eob-decoder

Try: *"What do Z00.00, 99213 and J0696 mean on this EOB?"* · *"Explain allowed amount versus billed amount."* · *"Billed 1,200, allowed 650, deductible 500, 20% coinsurance. Is my 630 patient responsibility right?"*

Run it yourself

npm install --legacy-peer-deps

npm run data:refresh # downloads the CMS/NCHS releases and rebuilds public/data npm test && npm run typecheck npm run dev # http://localhost:8787/eob

Test it

npm run dev                                   # terminal 1

npm run smoke -- http://127.0.0.1:8787/eob # terminal 2: initialize, tools/list, one call per tool, the prompt npx @modelcontextprotocol/inspector # point it at http://127.0.0.1:8787/eob (Streamable HTTP)

Or add the local server to Claude Code with claude mcp add --transport http eob-local http://127.0.0.1:8787/eob and ask it the reviewer prompts in docs/SUBMISSIONS.md. Problems: support@keepmd.org (the issue tracker is off).

Built on @modelcontextprotocol/server (createMcpHandler, stateless Streamable HTTP) and Cloudflare Workers with Static Assets for the code sets. Layout, release and data-refresh steps: CONTRIBUTING.md, docs/DEPLOY.md. Directory submissions (Anthropic, OpenAI, MCP Registry, Google, Meta, Grok, Cursor and others): docs/SUBMISSIONS.md. Bundles: plugin/ (Claude plugin), chatgpt/ (ChatGPT app package), .cursor-plugin/ + mcp.json (Cursor plugin), gemini-extension.json + GEMINI.md (Gemini CLI extension).
