sns-portugal-mcp

[!WARNING] Deprecated — use portugal-mcp instead. This server now lives on as the saude feature of portugal-mcp, together with IPMA weather, INE, Banco de Portugal, Parliament, public contracts and more. Install with uvx portugal-mcp (add PORTUGAL_MCP_FEATURES=saude to load only this part). Tool names: find_institutions → sns_find_institutions, emergency_stats → sns_emergency_stats, surgery_wait_stats → sns_surgery_wait_stats, consultation_wait_stats → sns_consultation_wait_stats, search_datasets → sns_search_datasets, query_dataset → sns_query_dataset. This repository gets no further updates.

MCP server for official open-data statistics about Portugal's national health service (SNS), so Claude (or any MCP client) can answer "how busy is the emergency department at Santa Maria?", "how many people are waiting for surgery in the Norte region?" or "which SNS hospitals are near me?".

Read-only, no key, no account. It uses only public open data. Not affiliated with the SNS, SPMS or the Portuguese Ministry of Health.

Statistics, not the live queue. The figures are official monthly statistics; the newest month is usually 2-3 months old and provisional. This server does not show live emergency-room waiting times. For those, see tempos.min-saude.pt.

Not medical advice. In an emergency call 112. For health advice call SNS 24 on 808 24 24 24.

Tools

find_institutions

Finds SNS hospitals and local health units (ULS) by name, or the nearest ones to a coordinate. Each result says whether the place reports emergency, consultation and surgery data, and gives stats_entity: the name the statistics use for it. Statistics are published per ULS or hospital group, not per building.

Parameters: query (name, accent-insensitive), lat / lon (sort by distance), emergency_only, limit.

emergency_stats

Emergency-department visits per month, by type (general, paediatric, obstetric, psychiatric) and by Manchester triage colour (red, orange, yellow, green, blue, white, not triaged), with each colour's share of the month. Covers one institution, one region, or the whole country.

Parameters: institution, region (Norte | Centro | LVT | Alentejo | Algarve), period ("YYYY-MM", latest month to include), months (default 6).

surgery_wait_stats

Surgery access per month:

• the surgical waiting list (LIC) at month end;
• the % of waiting patients still within the legal maximum guaranteed time (TMRG);
• the mean days from hospital admission to the operation (scheduled inpatient surgery);
• surgeries performed: scheduled (inpatient and day surgery) and urgent.

Same parameters as emergency_stats. The open data has no breakdown by specialty.

consultation_wait_stats

Hospital outpatient consultations per month (first and follow-up), plus the % of first specialist consultations (referred by a family doctor) held within the TMRG. Same parameters as above.

search_datasets

Searches the 149 datasets of the SNS Transparency portal by keyword. Titles are in Portuguese, so Portuguese keywords work best: "ocupação", "partos", "rastreios", "SNS 24", "INEM". Returns each dataset's id, description and field names.

query_dataset

Runs an ODSQL query (where, select, group_by, order_by, limit, offset) on any portal dataset. Use it for anything the tools above don't cover.

Year-to-date values

Most hospital-activity datasets publish year-to-date cumulative values, so the December figure is the annual total. The curated tools return both the year-to-date value and a derived in_month value (this month minus the previous one). If you use query_dataset directly, do that subtraction yourself.

Install

Quickest (needs uv): no clone needed, it runs straight from PyPI.

claude mcp add sns-portugal -- uvx sns-portugal-mcp

For Claude Desktop, use "command": "uvx", "args": ["sns-portugal-mcp"].

From source:

Requires Python 3.10+.

git clone https://github.com/ThiagoJacobLannes/sns-portugal-mcpcd sns-portugal-mcppython -m pip install -e .

On Windows, if you keep code in a cloud-synced folder (Google Drive, OneDrive), create the virtual environment outside it. Sync clients drop desktop.ini files into folders, which can crash packages on startup.

Add to Claude Code

claude mcp add sns-portugal -- python -m sns_portugal_mcp.server

Add to Claude Desktop

Merge claude_desktop_config.snippet.json into your Claude Desktop claude_desktop_config.json, then restart Claude Desktop:

{  "mcpServers": {    "sns-portugal": {      "command": "python",      "args": ["-m", "sns_portugal_mcp.server"]    }  }}

Data sources

Datasets used by the curated tools:

Data derived from these sources keeps the source's terms. The code in this repository is MIT-licensed.

What this server does not do. It does not call tempos.min-saude.pt/api/*: that API needs a key embedded in the site's own web app, and this server does not use other people's keys. It also does not scrape the live waiting-time report (an embedded Power BI report).

How it works

The server calls the portal's public Explore API with httpx and aggregates in the query itself (group_by tempo, sum(...)), so regional and national totals are computed on the server side. Hospital names are matched without regard to accents. A hospital such as "Hospital de Faro" is mapped to the ULS it reports under ("ULS do Algarve") using the institution list. The dataset catalog, the institution list and the institution names are cached in memory for 6 hours. If an upstream call fails or a query is malformed, the tool returns a clear {"error": ...} and does not guess.

Environment overrides (optional): SNS_ODS_BASE_URL, SNS_INSTITUTIONS_URL.
