Honest Nfz

Local MCP server for the Polish National Health Fund (NFZ) public API — waiting lists ("kolejki") and the medical-service dictionary. No authentication required.

Part of the honest-mcp family of small, auditable, local-first MCP servers.

Why

Every Polish resident, at some point, wants to know "jak długo trzeba czekać na kardiologa?" — how long the queue for a cardiologist actually is. NFZ publishes this via a REST API but the friendly search on terminyleczenia.nfz.gov.pl doesn't help when you want to compare 20 providers at once or feed the data to an AI.

This server hands NFZ's data to your AI as structured JSON. Ask "cheapest wait time for a rehabilitation-cardiology facility in Mazowieckie?" and get an actual answer with provider names, wait statistics and — where NFZ provides them — first-available dates.

Features

Three tools:

• search_queues — waiting list search: partial-name benefit + province + case (routine vs urgent) + optional locality (city/district), returns the first-available date (NFZ currently often leaves it empty) and the provider-reported wait statistics per provider.
• search_benefits — search the NFZ service dictionary to discover the exact benefit name to use.
• list_provinces — the 2-digit province code map (01–16).

Data source

• Endpoint: api.nfz.gov.pl/app-itl-api/ — NFZ's public "Informator o Terminach Leczenia" API
• No API key, no registration
• Public info about NFZ-contracted providers only

Requirements

• Python 3.10+

Setup

git clone https://github.com/bartosz-kuc/honest-nfz-mcp.git
cd honest-nfz-mcp
python3 -m venv venv
./venv/bin/pip install -r requirements.txt

On Windows use python instead of python3, and venv\Scripts\pip / venv\Scripts\python instead of the venv/bin/... paths (here and in the configs below).

Register with Claude Code:

claude mcp add nfz /absolute/path/to/venv/bin/python /absolute/path/to/server.py

Claude Desktop claude_desktop_config.json:

{
  "mcpServers": {
    "nfz": {
      "command": "/absolute/path/to/venv/bin/python",
      "args": ["/absolute/path/to/server.py"]
    }
  }
}

Example usage

Note (September 2026): NFZ's API currently returns no dates for most queue entries, so first_available_date is often null. NFZ has also renamed many services (e.g. ŚWIADCZENIA Z ZAKRESU OKULISTYKI instead of PORADNIA OKULISTYCZNA) — use search_benefits to find the current wording.

"Which cardio-rehab facilities in Mazowieckie have the shortest wait?"

Two-step: search_benefits(name="kardio") → find exact benefit name → search_queues(benefit="ZAKŁAD/OŚRODEK REHABILITACJI KARDIOLOGICZNEJ", province="07", case=1, limit=25) → list of providers with their queue data.

"Any ophthalmology openings in Kraków?"

search_queues(benefit="ŚWIADCZENIA Z ZAKRESU OKULISTYKI", province="06", case=1, locality="KRAKÓW") — locality is a case-insensitive substring filter applied by the NFZ API, so it covers the whole province, not just the first result page. Matches are re-checked locally, scanning at most 10 result pages of 25.
