Perplexity: the web plus a verified legal corpus

Perplexity searches the web and cites what it finds. For legal matters, however, that is not enough: full texts of legislation are scattered, case law is hidden in court databases, and results from discussion forums are not a reliable source. The Europaius connector gives Perplexity access to a structured legal corpus.

How this differs from web search

When you ask Perplexity about a notice period, it will find articles from advisory websites and answer based on those. Such an article may be outdated or relate to a different situation. The connector instead returns the exact statutory provision in its current wording, along with court decisions interpreting it. Perplexity can still combine both: context from the web and binding text from the corpus.

The corpus also contains material you will rarely find on the open web: 980,000 Czech court decisions with full text and full-text search, citation links between provisions, and legislation from 25 EU countries, including Ireland / Cyprus / Malta, in the original language.

Connecting the connector

Perplexity allows you to add custom MCP connectors in your account settings (Settings → Connectors). This feature is available on paid plans. After entering the address https://mcp.europaius.com/mcp, Perplexity will open the Europaius login screen, where you enter your email address and the code sent to you. The connector is then available in all threads, and you can enable it for a specific query.

If your version of Perplexity only offers connectors in the Mac desktop app, add it there; the setting is tied to your account.

Limitations

Perplexity decides on its own when to call the connector. If you want certainty, name it explicitly in your query. For foreign jurisdictions, the first search takes longer because extensive full-text databases are being searched; repeated queries are fast. The free Europaius account allows 100 queries per day, and each tool call counts as one query.
