DirectCase Legal Search — documentation

Overview

The connector turns Claude into a legal-research assistant grounded in primary sources. Once connected, Claude can call DirectCase tools to find and read court decisions, statutes and regulatory rulings, look up companies in public registries, and return answers with verifiable citations. The tools available to you depend on the country your DirectCase account is set to and your subscription tier — see Tools by country.

Getting started

Connect to Claude

1. 1

   Add a custom connector

   In Claude, open Settings → Connectors → Add custom connector.

2. 2

   Enter the connector URL

   Paste the DirectCase endpoint: https://mcp.directcase.ai

3. 3

   Sign in with DirectCase

   Claude opens the DirectCase sign-in (WorkOS, login.directcase.ai). Log in or create an account. Authentication uses OAuth 2.1 — we never see your password.

4. 4

   Approve access

   Approve the connection. The DirectCase tools then appear in Claude and you can start asking legal questions.

Authentication

Access requires a DirectCase account. When you connect, Claude opens the DirectCase sign-in hosted by WorkOS AuthKit (login.directcase.ai) and the connection authorizes over OAuth 2.1. We receive a token carrying your user id, email, subscription tier and a country claim — we never receive or store your password. The token's country and tier determine which tools and sources you can use.

Supported clients

The connector works with any MCP-compatible client, including:

• Claude.ai (web)
• Claude Desktop
• Claude Code
• Any MCP-compatible client

Example prompts

Once connected, paste any of these into Claude. Each shows the expected outcome — which tool Claude uses and what comes back.

• “What has the Czech Constitutional Court said about the right to a fair trial in tax proceedings?”

  What happens: Claude calls Search Case Law across the constitutional and administrative courts and answers with specific decisions (e.g. an Ústavní soud nález), each linked to its full text on directcase.ai.

• “Quote the exact wording of § 2 of the Czech Civil Code (Act No. 89/2012 Coll.).”

  What happens: Claude calls Get Law Text and returns the verbatim text of § 2 from the official e-Sbírka, with a citation to the source — no paraphrasing.

• “Look up the company with IČO 24337269 and tell me if it is in insolvency.”

  What happens: Claude calls Search Company Registry and the insolvency register, returning the company’s registry details and current insolvency status from the Czech business registries.

• “Find the decision Pl. ÚS 33/97 and summarise its holding.”

  What happens: Claude calls Search by Identifier to locate the exact case, fetches the full text, and summarises the holding with a link to the decision.

• “Which DirectCase tools can I use on my current plan?”

  What happens: Claude calls Account & Entitlements and lists your subscription tier, jurisdiction and the exact set of tools available to your account.

Tools

The connector exposes 14 tools, grouped below. Each entry shows its raw tool name, where it is available, and its input parameters. Internal tracking parameters are managed by the app and are not shown. For per-jurisdiction availability see Tools by country.

Sources by country

Each jurisdiction maps to a fixed set of source collections (courts, legislation databases and regulatory authorities). These are the collections the search tools query for that jurisdiction. Codes such as cz_us can be passed to a tool's collections parameter to narrow a search.

Tools by country

The tools exposed to your account depend on its jurisdiction. The list below shows the MCP tools available in each jurisdiction; get_entitlements and get_document are available everywhere, while statute-text and company-registry tools are currently Czech-only.

Coverage lookup

The tools you see depend on your account: the country it is set to and your subscription tier. Pick a country below to see exactly which tools are available there and the sources behind them. You can always call “Account & Entitlements” inside Claude to confirm what your own account can access.

Rate limits

Each tool has a per-tier call limit within a rolling window. Heavy agentic search tools have lower limits than light lookup tools. The free Basic tier uses a ~100-day window (effectively a lifetime cap); paid tiers reset every 24 hours.

The agentic search tools (Search Case Law, Search Legislation, Search Regulatory Decisions) may also be called only once per conversation.

FAQ

Which tools will I get?

It depends on the country your DirectCase account is set to and your subscription tier. Use the country selector above, or call “Account & Entitlements” in Claude to see your exact set.

Why don’t I see a particular tool?

A tool is hidden when it has no data source for your jurisdiction (for example, statute-text lookup and company registries are currently Czech-only) or when your tier does not include it.

How often can I use the AI search tools?

The agentic search tools (Search Case Law, Search Legislation, Search Regulatory Decisions) may be called once per conversation, and are also subject to your tier’s rate limits.

Is it free?

Yes — the connector works on a free Basic tier. Paid Premium, VIP and Pro tiers raise the daily limits.

How is my data handled?

See the DirectCase Privacy Policy for what the connector processes and how long it is retained. Queries are processed to return results and are not retained beyond operational logs.
