Pull State Statutes in Claude Desktop

The `get_state_statutes` tool fetches current legislative text for any US state directly into your chat window. You ask for California's environmental protection laws, and your agent retrieves the exact statutory language without making you open a browser tab. This means you stop copy-pasting from public legal portals. When drafting a memo or reviewing compliance requirements, Claude pulls the primary source material immediately. You get the raw legal text, ready for analysis or citation formatting.

Query Justia Case Law

The `search_legal_cases` tool queries the Justia database to find relevant judicial decisions. Give Claude a specific legal issue or a party name, and it pulls back summaries and citations for matching cases. You do not have to switch context to hunt down precedent. The MCP Server handles the search logic and returns the results straight to your workspace. If you need to verify a citation before relying on it, the agent runs the search and confirms the case exists.

Automate Legal Research with this MCP Server

Combining `search_legal_cases` and `get_state_statutes` gives you a complete research loop inside Claude. Your agent can find the controlling statute, then immediately search for how courts have interpreted it. Doing this manually takes hours of clicking through legal databases. Here, the agent executes both queries sequentially, reading the results and synthesizing a memo based on actual, retrieved legal authority rather than hallucinated text.

Common questions about Justia Legal Intelligence MCP in Claude Desktop

Open `claude_desktop_config.json` via Settings -> Developer. Add the server details under the `mcpServers` key, save the file, and restart the app completely.

Yes. Go to Settings -> Integrations in Claude Web, click Add custom connector, and paste the remote MCP URL. The tools will appear in your browser chat immediately.

The tools pull public legal data. You just need the standard endpoint token provided by Vinkius to authenticate the MCP connection.

The search relies on Justia's indexing. If a case is unpublished, very recent, or sealed, the API might not return it. Always verify critical citations directly if the search comes up empty.

The server processes your search terms, case names, and requested jurisdictions. Vinkius runs this MCP Server in an ephemeral V8 Isolate Sandbox, meaning your specific litigation strategies and query histories are destroyed immediately after the API call completes.
