What changes for legal research
With this connector, you ask Claude in plain language and it searches one database built from official registries such as Légifrance, EUR-Lex, the BOE or the European Court of Human Rights, then opens the full text of the decision or law it finds, with its source.
Find the decisions that matter. search mixes meaning-based and keyword search over the corpus, with filters on country, court level, jurisdiction, language and dates, and returns ranked results with snippets.
Turn a sloppy citation into the right document. resolve_reference takes an informal reference such as an article of a civil code, an ECLI or a CELEX number and returns the matching text. get_document then brings the full text and metadata.
Know what is covered before you rely on it. discover_countries, discover_sources and get_filters show which countries, courts and filter values exist, which the publisher presents as the way to build precise queries.
And what it does not do. It reads public law, and no listed tool edits a document. Its one outgoing tool only reports a problem with a source to the maintainer. The publisher stresses primary sources only, with no scraped web copies. Nothing runs on its own either: a new ruling does not trigger Claude. To browse the rest of the family, the Integrations hub lists it.
The vocabulary in one minute
Five words you will run into when you plug it in.
- Connector
- The link you set up once between Claude and a service you use, so Claude can search it while it answers your question.
- Tool
- One named capability the connector gives Claude. Claude chooses which ones to call; the directory lists every tool by name.
- Authorization
- The service's own sign-in page, where you grant Claude the access it will use. Given once per person, and you can revoke it.
- Approval
- The confirmation Claude waits for before it completes an action that changes something, displayed in the chat when it counts.
- MCP
- The shared standard behind connectors: it is what lets an assistant like Claude query an outside service like this database.
Connect Legal Data Hunter to Claude in three steps
- 01
Find it in Claude
Open Customize, then Connectors, and look for Legal Data Hunter. On a Team or Enterprise workspace, an Owner or Primary Owner enables the connector for the organization before members connect one by one.
- 02
Launch the connection
Click Connect on its row, then sign in on the page Legal Data Hunter opens in your browser. If the link stops working later, Disconnect and connect again.
- 03
Read the authorization
Review the authorization screen before you accept it. It belongs to the service, not to Claude, and it states what the access covers. You can withdraw that access later from the service as well.

What Claude reads (6)
6 toolsSix tools that search, resolve, open or map the legal corpus without changing anything.
search
Runs a combined meaning and keyword search across the whole corpus and returns ranked results with titles, snippets and scores. Filters narrow it by country, court tier, jurisdiction, language or date range.
resolve_reference
Takes a loose legal citation, like an article number with a code name, a German court file number, an ECLI or a CELEX identifier, and finds the exact document behind it.
get_document
Opens one decision or legislative text in full, with all its metadata, using the source and identifier that a search returned.
discover_countries
Lists every country present in the database with its document counts, broken down by type. The publisher suggests starting there to see coverage.
discover_sources
For one country, shows the official sources behind its documents, such as courts and legislative bodies, each with a document count and the date range it spans.
get_filters
Returns the filter values a given source supports: courts, chambers, jurisdictions, decision types, languages and dates. Claude uses them to aim a search precisely.
What Claude sends (1)
1 toolOne tool that sends a report to the maintainer. No source describes a confirmation for it, so the general rule below applies.
report_source_issue
Approval: see the ruleSends a report straight to the maintainer when something is off: a broken link, missing data, an indexing error or a quality problem in a source.
What Claude asks before it acts
By default, Claude stops and asks before any action it takes on an account for you. Here that rule mostly concerns the one tool that sends something out, the source report.
On a Team or Enterprise workspace, owners decide whether members can let some actions through without being asked every time. They can also limit what a connector may do for the whole organization, such as allowing searches while closing anything that sends, and nobody overrides that from a personal account. Claude works with the access of the person who connected it, nothing more. The official read-only versus write labels per tool appear only in a connected account's settings.
Which plans it is on
Out of 819 sheets in the official directory, none shows availability per plan. Connector by connector, that answer is not published anywhere.
The general rule is published: remote connectors are open to all users on Claude, Cowork, Claude Desktop and mobile. On Team and Enterprise, an Owner or Primary Owner enables a connector for the organization before members can connect individually. For the up-to-date state of Legal Data Hunter, check its sheet in the official directory from your own account.
Where this connector stops
A connector is not an automation. Claude calls these tools while it answers you: no new judgment or amended law starts anything by itself.
The tool list is an observed floor, not a ceiling: an administrator could open more than any public page shows. The partner badge in the directory is not a security audit, and Anthropic writes on every sheet that it neither chooses the tools a publisher exposes nor guarantees they behave as described. Only the publisher documents this connector; Claude's help center has no page on it. Even the corpus size differs between two of its texts, as shown below.
How large is the Legal Data Hunter corpus?
- Claude directory sheet (publisher's text) ↗read October 2026Out of dateThe sheet announces tens of millions of documents across more than 160 jurisdictions, with over 180 registries beyond the ones it names.
- Publisher's llms.txt file ↗read October 2026The file, generated from the database, gives a much higher document count and a larger number of countries, with exact figures.
What this page followsBoth texts come from the publisher, and they disagree. The machine-generated file reads as the current one; the directory sheet carries an older, smaller figure. Neither can be checked from the outside and the corpus keeps growing, so treat any count as a snapshot and ask Claude which sources it actually searched.
