ICF MCP Server (Cloudflare Workers)
A Model Context Protocol (MCP) server for the WHO International Classification of Functioning, Disability and Health (ICF), deployed on Cloudflare Workers for global edge availability.
Live URL: https://mcp-icf.medseal.app/mcp
What is ICF?
The ICF is a WHO classification that complements ICD (diagnosis codes) by describing how health conditions affect a person's functioning in daily life:
- Body Functions (b) - Physiological and psychological functions
- Body Structures (s) - Anatomical parts of the body
- Activities and Participation (d) - Task execution and life involvement
- Environmental Factors (e) - Physical, social, and attitudinal environment
Tool
A single icf tool with action dispatch (token-efficient). 19 actions:
Codes & Hierarchy
| Action | Description |
|---|---|
lookup | Look up a specific ICF code (e.g., b280, d450) |
search | Search by keyword (e.g., "walking difficulty", "pain") |
browse | Browse a category (b, s, d, e) or sub-chapter (b1, d4, e3) |
children | Get subcategories of a code |
parent | Navigate up to a code's parent category |
siblings | Codes at the same level (same parent) |
chain | Full hierarchy path from root to a code |
profile | Build a functional profile from multiple codes |
Qualifiers
| Action | Description |
|---|---|
qualifier | Component-specific qualifier reference (b=1, s=3, d=2, e=barrier/facilitator) |
validate | Validate code format + qualifiers, verify existence in the WHO API |
parse | Parse fully qualified codes (d450.23, s730.312, e120+3) |
Clinical Assessment Instruments
11 standardized RPM instruments with items, scoring, and ICF mappings: GAD-7, PHQ-9, RADAI-5, SLEDAI-2K, WHODAS 2.0, HAQ-DI, PROMIS-10, CAT, ODI, NRS Pain, Short FES-I.
| Action | Description |
|---|---|
instruments | List instruments, optionally filtered by domain |
instrument | Full spec: items, response options, scoring, ICF mappings |
score | Score responses → severity, interpretation, ICF qualifier |
suggest | Suggest instruments for a condition, ICF code, or domain |
mapping | Show an instrument's ICF code mappings |
Meta
| Action | Description |
|---|---|
overview | Full ICF classification overview |
api | Raw WHO API request (escape valve) |
help | Action reference with examples |
Example call:
{"action": "score", "name": "GAD-7", "responses": [1, 2, 1, 0, 1, 2, 1]}
Instrument and qualifier actions are pure logic and work without WHO API credentials; code/hierarchy actions require them.
Prerequisites
- WHO ICD-API credentials (free): Register at https://icd.who.int/icdapi
- Cloudflare account with Workers enabled
- Node.js 18+ and npm
Installation
git clone https://github.com/stayce/icf-mcp-cloudflare.git
cd icf-mcp-cloudflare
npm install
Configuration
-
Copy the example environment file:
cp .dev.vars.example .dev.vars -
Edit
.dev.varswith your WHO API credentials for local development. -
For production, set secrets:
wrangler secret put WHO_CLIENT_ID wrangler secret put WHO_CLIENT_SECRET
Development
npm run dev
The server will be available at http://localhost:8787.
Testing
npm test
Regression tests cover instrument scoring (all 11 instruments) and qualifier parsing — pure logic, no WHO API credentials needed.
Deployment
npm run deploy
For custom domain (configured in wrangler.toml):
wrangler deploy --env production
Usage with Claude

{
"mcpServers": {
"icf": {
"type": "url",
"url": "https://mcp-icf.medseal.app/mcp"
}
}
}
Or if deploying your own:
{
"mcpServers": {
"icf": {
"type": "url",
"url": "https://your-worker.workers.dev/mcp"
}
}
}
Endpoints
