Trellis, the largest legal research platform for state trial courts, has released a connector that gives Claude direct access to a dataset spanning 45 states, more than 3,000 courts, and 2,500+ counties. The connector is available now in the Claude connector marketplace and works on Claude web, desktop, and mobile. New users can try it for free without a separate Trellis login.
What the dataset covers
The Trellis dataset includes dockets, rulings, verdicts, filings, judge analytics, attorney profiles, and expert witness records. It focuses on state trial courts, which handle the vast majority of civil litigation in the U.S. but have been largely overlooked by traditional legal research platforms that concentrate on appellate courts.
What you can do with it
With the Trellis connector, you can ask Claude in plain English to:
- Research how a specific judge has ruled on motions
- Profile opposing counsel's litigation history
- Pull verdicts and damages awards in comparable cases
- Surface relevant filings and pleadings
- Vet expert witnesses
All queries are grounded in actual trial court records. There is no need to log in to Trellis separately or switch between tools.
Pricing and access
The Trellis connector is included in all active Trellis subscriptions at no additional cost. New users can try it for free by connecting to Trellis directly from the Claude connector marketplace. Setup instructions are available at support.trellis.law/trellis-law-mcp-connector.
Context
The launch coincides with Anthropic's broader expansion of Claude into the legal industry. Trellis contributes the state trial court layer — cases, rulings, motions, verdicts, judge and attorney analytics that have historically been inaccessible through traditional legal research tools.
Bottom line
For litigators and legal researchers, the Trellis connector turns Claude into a practical research tool for state trial court data that was previously difficult to access at scale. The free trial makes it easy to evaluate without commitment.
