io.github.MoleCarePublished by GitHub account MoleCarev1.2.0Updated Oct 30, 2026
Educational dermatology knowledge and mole tracking. No credentials needed. Not a medical device.
Overview
Local MCP server giving assistants a bundled educational dermatology knowledge base, SNOMED CT/ICD-10 helpers and optional MoleCare mole-tracking API tools.
- What you can do
- Search and read educational dermatology knowledge: ABCDE criteria, Fitzpatrick types, prevention, when to see a clinician
- Look up and search SNOMED CT concepts and map them to ICD-10 categories, with provenance metadata
- Describe lesion features in ABCDE style and list named educational risk factors and progression stages for conditions
- Run reusable prompts for walking through ABCDE, preparing a dermatology appointment and explaining a SNOMED code
- Query MoleCare product data (moles, analyses, change history, risk profile, comparisons) when a backend is configured, otherwise labelled mock data
- When to use it
- Useful when you want an assistant to explain skin-health terminology, ABCDE concepts or SNOMED/ICD-10 codes, or to prototype assistant flows against a MoleCare-compatible API. It is an educational aid, not a diagnostic tool.
- Requirements
- Runs locally via npx with Node.js; no credentials, database or network needed for the knowledge tools. Optional MOLECARE_API_URL and MOLECARE_API_KEY connect a real MoleCare-compatible backend; LOG_LEVEL sets verbosity. A separate molecare-ops-mcp binary adds internal ops tools.
Installation
In SourceWeft
- Open Molecare Mcp in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.

MoleCare MCP Server
[npm version] [npm downloads] [License] [Node] [MCP] [Contributors]
Model Context Protocol (MCP) server that gives Claude and other MCP clients access to:
- Dermatology knowledge — ABCDE education, SNOMED CT / ICD-10 helpers, risk-factor prompts
- Optional MoleCare API tools — moles, trends, analysis (your backend + API key)
- Optional MLOps / ops tools — shipped as a separate binary,
molecare-ops-mcp(mock-first)
Not a medical device. Outputs are educational and operational aids only. Do not use for diagnosis or treatment decisions.

One command, no API key, no database. Real output from the published package.
Why this exists
MoleCare helps people track moles over time and prepare for clinician visits. This MCP server lets developers and operators:
- Query educational skin-health knowledge from Claude Desktop / Cursor
- Prototype assistant flows against a MoleCare-compatible API
- Explore MLOps tooling with safe mock data when no credentials are set
Quick start
No credentials, no database, no cloud account. Add this to your MCP client config and restart it:
For Claude Desktop on macOS that file is
~/Library/Application Support/Claude/claude_desktop_config.json.
The dermatology knowledge tools work immediately — they read from a knowledge base bundled in the package. Everything that talks to a backend returns clearly-labelled mock data until you configure it, so you can explore the whole tool surface before deciding whether you want any of it.
To try it without a client at all:
It starts and waits on stdio. No output means it is working.
Claude Code plugin
This repository is also a Claude Code plugin: the same server, plus a skill that tells Claude when to use it and to never diagnose.
Then ask things like "what does the E in ABCDE mean?" or "help me prepare for a
dermatology appointment". The plugin runs npx -y molecare-mcp with no keys, so
the account tools return example data marked "dataSource": "mock".
Connecting a real backend
Only needed if you are running a MoleCare-compatible API:
Use localhost (or your own deployment). Do not paste production keys into config files that sync to cloud drives.
Environment variables
Every setting is optional. The public server falls back to mock product data
without API credentials, and its knowledge tools continue to work offline. For
the operations server, use NODE_ENV=development (the .env.example default)
to keep integrations in mock mode.
Shared by both binaries
Public server (molecare-mcp)
The public server has no additional settings. Its dermatology knowledge works without configuration; the shared MoleCare API variables enable its optional mole and profile tools.
Operations server (molecare-ops-mcp)
The operations binary also accepts the shared settings above. These additional variables only configure its infrastructure, monitoring, and CI/CD tools:
See .env.example for the copyable source-of-truth list.
Tools
Dermatology knowledge — no setup required
These are the reason most people install this. They answer from a bundled knowledge base and need no API, no key, and no network.
Resources: molecare://knowledge/* — ABCDE criteria, Fitzpatrick skin types,
prevention, when to see a dermatologist. molecare://ontology/* — SNOMED CT and
ICD-10 reference lists, the full snomed-icd10-map mapping table, and risk
factors, all with provenance metadata.
Educational prompts
The server also exposes three reusable MCP prompts: walk_through_abcde,
prepare_dermatology_appointment, and explain_snomed_code. They help a client
organize observations or explain terminology without diagnosing a condition,
assigning urgency, or producing a risk score. Every rendered prompt includes
the non-diagnostic educational disclaimer; the terminology prompt requires a
SNOMED CT code argument.
What the terminology actually covers
Every SNOMED concept the server advertises resolves through
lookup_medical_concept and maps through map_snomed_to_icd10. Ask for a code
outside the subset and the response carries a coverage block listing what is
bundled, rather than an empty result. Browse the whole table with the
molecare://ontology/snomed-icd10-map resource.
ICD-10 coverage is deliberately broader than SNOMED coverage. Expanding the bundled SNOMED concept set is on hold pending a redistribution question with SNOMED International: free use in a member country is not the same as free redistribution via npm to non-member territories (#49). WHO licenses ICD-10 more permissively at this level, so that side can grow in the meantime.
Terminology provenance
Bundled SNOMED CT / ICD-10 helpers are an educational subset, not a licensed
terminology distribution. Named sources live in
src/resources/terminology-provenance.ts
and are returned on map_snomed_to_icd10 and the ontology resources:
The dataset itself lives in
src/resources/terminology-data.ts and is
the single source for both the src/api/ontology-client.ts mock paths and the
ontology resources. Educational prose without clinical codes lives in
src/resources/medical-kb.ts.
MoleCare product data — needs an API
Returns labelled mock data until MOLECARE_API_URL is set.
Operations and MLOps tooling (39 tools — separate molecare-ops-mcp binary)
These exist because MoleCare operates this stack from an assistant. They are of little use outside that context, and all of them return mock data unless the matching backend is configured.
They are not part of the molecare-mcp tool list. Loading 39 infrastructure
tools that nobody outside MoleCare can use made it measurably harder for a model
to pick the right dermatology tool, so they live in their own server:
The AWS tools need @aws-sdk/client-ec2 and @aws-sdk/client-cloudwatch, which are
optional peer dependencies — they are not installed by default, because they add
33 MB that nobody wanting the dermatology tools should have to download. Install them
yourself if you want live AWS data:
Architecture
Docker
Security
- Never commit
.envfiles or API keys — see SECURITY.md to report a vulnerability - Prefer mock mode for demos and screenshots
- Tools that accept
userIdcan return PHI only if you point them at a real backend with real auth — treat that as production - Rate-limit and auth belong on your API, not only on the MCP process
Medical disclaimer
MoleCare MCP provides educational information and developer tooling. It does not diagnose melanoma or any disease. Always consult a qualified clinician for medical concerns.
Development
Contributions are welcome. Read CONTRIBUTING.md first — it covers the mock-first rule,
the clinical-safety boundary for anything touching medical content, and how to pick up a good first issue.
Please keep secrets out of examples and prefer localhost defaults.
