eaa-cite

eaa-cite is a dataset and a tool for the European Accessibility Act (EAA), the EU law that requires online shops and other services to be accessible from June 2025. For the EU and three member states it records what the law requires, and every value carries a citation: the article, a verbatim quote and the official source. It also scans web pages with axe-core and files the results under the EN 301 549 clauses they relate to. You can use it from the command line, as a TypeScript library, or as an MCP server that an AI assistant such as Claude can call.

That is real output from npm run demo, which starts the server over stdio and calls it the way Claude Desktop does.

Why

The legal answers that matter most about accessibility (the highest fine, whether a small business is exempt, how long an old contract may run) are the ones most often paraphrased wrong or copied from the neighbouring country. Here every value is a claim with a citation: the source, the article, a verbatim quote in the source's language, and an English translation. A monthly job re-reads every official source and fails if a quote is no longer there. The reasoning is in ADR 0001.

What is in it

• A dataset of four jurisdiction files in data/jurisdictions/: the directive itself, Sweden, Germany and Spain.

• The EN 301 549 v3.2.1 clause 9 table: 50 WCAG 2.1 A and AA criteria with their EN clause numbers, in data/en-301-549-v3.2.1-clause9.json.

• An MCP server with six tools: get_obligations, compare_jurisdictions, conformance_statement, explain_criterion, scan_url and scan_html. No model runs inside it.

• A TypeScript library with the same lookups and the scanner.

• npm run verify-sources, which checks every quote against its live source.

The dataset at a glance

Each value links back to a quote in the jurisdiction files.

Quick start

Node 22 or later. Tested on Ubuntu and macOS.

git clone https://github.com/Rez-1/eaa-cite && cd eaa-cite
npm install
npx playwright install chromium
npm run build
claude mcp add eaa-cite -- node "$(pwd)/dist/mcp/bin.js"

The last line adds the server to Claude Code. Its scan_url tool loads any URL the assistant gives it, including localhost and private network addresses, so only run it where that is fine (see SECURITY.md). For Claude Desktop and other clients, see docs/mcp-setup.md. Full install notes are in docs/install.md.

From the terminal:

node dist/cli/main.js scan https://shop.example/   # failures by EN 301 549 clause
node dist/cli/main.js obligations de penalties     # the value, its article and quote

The four commands are in docs/usage.md.

As a library:

import { getJurisdiction, conformanceFor } from "eaa-cite";

getJurisdiction("ES").claims.penalties.value.maxFine; // 1000000
conformanceFor("SE").status; // "not_cited"

Documentation

• docs/install.md: install from source, then add the server to a client

• docs/usage.md: every tool, command and library function, and how to read what they return

• docs/limitations.md: what the data and the scans do not cover; common questions are in the FAQ

• docs/contributing-data.md: correct or add data, with links to the file format and source verification

• docs/architecture.md: the code, the decision records and the system it came from

• examples/README.md: the test shop and its results

• CONTRIBUTING.md, SECURITY.md and the glossary, CONTEXT.md
