Why bring Trellis into your litigation prep
Trellis collects U.S. state trial court data: dockets, rulings, verdicts and filings. The connector lets you query it from a conversation. Describe the case, the judge or opposing counsel, and Claude goes and fetches the matching records and numbers, so you're not clicking through search screens one filter at a time.
Find the comparable cases. The docket search filters by party, judge, firm, practice area, date or disposition, and a companion tool opens any case in full. Another runs full-text search across motions, orders and complaints.
Know your judge. The judge profile covers bio, appointing authority, career history and courtroom rules, while the analytics side adds motion grant rates and outcomes by matter type.
Put a number on the risk. Verdict search filters by award range, injury type, expert or attorney, and the verdict statistics turn that into averages, medians and extremes by practice area.
Now the limits. Trellis states that none of its tools create, modify or delete data, so the sheet is for looking things up. Some complaints aren't available as full text yet, and coverage varies by jurisdiction. And nothing runs on its own: no tool alerts you when a new case gets filed. That kind of monitoring is an automation tool's job, a different trade; the Integrations hub covers that side.
The jargon, in one minute
Five terms you'll see while connecting Trellis.
- Connector
- The link you set up once between Claude and an account you already have, so Claude can work in it while it answers you.
- Tool
- One named thing a connector lets Claude do. Claude picks the ones it needs on its own, and the directory lists them by name.
- Authorization
- Trellis's own sign-in screen, where you hand Claude the access it will use. Granted once per person and withdrawn the same way.
- Approval
- The confirmation Claude waits for before finishing something that changes your account, shown in the chat when it matters.
- MCP
- The shared standard connectors are built on, which is what lets an assistant like Claude talk to an outside service.
Connect Trellis to Claude in three steps
- 01
Find Trellis in Claude
In Claude's settings, open Customize, then Connectors, and look for Trellis. On a Team or Enterprise workspace, an Owner or Primary Owner switches the connector on first so each member can sign in.
- 02
Start the connection
Hit Connect on its row and sign in through the window Trellis opens itself. You'll need a Trellis account, or to create one on the spot. If the link breaks, Disconnect and connect again.
- 03
Read the authorization screen
Before you accept, read the authorization screen. It belongs to Trellis, not Claude, and it sets what the access covers. You can also withdraw that access later from your Trellis account.

What Claude looks up (22)
22 toolsInstructions, dockets, filings, rulings, verdicts, judges, parties, experts and analytics: per Trellis, everything reads and nothing writes.
get_server_instructions
Hands Claude the general instructions for the Trellis server. The documentation says this is the one to call first, before any search runs.
list_skills
Lists the ready-made research workflows Trellis offers Claude, each one under its own name, so you can see what's already packaged. Each skill can then be opened with get_skill.
get_skill
Fetches the full instructions for one named workflow. The name comes from the list that list_skills returns, and what comes back is a set of workflow instructions rather than court data.
Search-get_server_instructions
Supplies the usage rules for the search part of the server, the side that covers dockets, filings, rulings, judges and experts. They are separate from the general instructions returned by get_server_instructions.
Analytics-get_server_instructions
Passes along the usage rules for the analytics side, separate from search, which computes statistics on judges, firms and verdicts. Its counterpart for the search side is Search-get_server_instructions.
Search-search_cases
Queries state court dockets by party, judge, firm, practice area, date or disposition. The full-case tool then opens any case in full from its docket ID.
Search-get_case
Takes a docket ID and returns the full record of a case: parties, procedural events, verdict and classification.
Search-get_case_complaints
Retrieves the complaint for a case, the original plus any amended versions if you want them, with full text included.
Search-search_documents
Runs full-text search across court filings such as motions, orders and complaints, with facets to narrow the results down. A single filing found this way opens with the single-filing tool, from its PDF ID.
Search-get_document
Pulls up a single filing by its PDF ID, with the document text included if you ask for it.
Search-get_ruling
Returns the full text of a ruling and its metadata from the ruling ID, so you see the judge's reasoning in their own words. It returns the ruling itself, not the docket around it, which the full-case tool covers.
Search-search_verdicts
Looks through verdict records by award range, injury type, expert, attorney or party, to place a case against its precedents. For aggregate figures rather than individual records, the verdict statistics tool is the matching tool.
Search-search_judges
Locates a judge by name, state or county and returns the judge ID that the profile and analytics tools then use. The judge profile tool and the judge analytics tool both work from it.
Search-get_judge_profile
Pulls together a judge's full profile: bio, appointing authority, career history, courtroom rules and clerk phone number. For figures on how the judge rules, the judge analytics tool is the separate tool.
Search-search_experts
Finds expert witnesses by name, by state or by specialty group, to build a shortlist of candidates for a case. The valid specialty labels come from the specialties tool, and Trellis's description lists expert witness vetting among the connector's uses.
Search-get_specialties
Returns the expert specialties Trellis recognizes, optionally filtered by group, which gives the valid labels for an expert search. The expert search can then use them.
Search-get_matter_types
Lists the valid sub-classifications of matters for a given practice area, so search filters match Trellis's own vocabulary. The list depends on the practice area you name.
Search-search_parties
Finds cases involving a specific plaintiff, defendant or any other party who isn't an attorney. Attorneys aren't the target here: Trellis describes it for non-attorney parties only.
Analytics-get_judge_analytics
Computes in-depth analytics on a judge: motion grant rates, procedural milestones and outcomes by matter type. The judge ID it needs comes from the judge search.
Analytics-get_lawfirm_analytics
Builds a firm's litigation profile: case counts, practice areas, how its attorneys are distributed, and trends. Trellis's description lists opposing counsel analytics among the connector's uses, next to judge analytics.
Analytics-get_verdict_stats
Aggregates verdicts into average, median, minimum and maximum awards, broken down by verdict type and by practice area. It works on aggregates, not on the individual records that the verdict search returns.
Analytics-get_verdict_stats_by_attorney
Ranks plaintiff and defense firms by the total verdict awards they've secured, giving a top list on each side. Per Trellis's documentation, the ranking is by total verdict awards.
Undocumented (2)
2 toolsThe directory publishes these two names. Trellis's technical documentation doesn't list them, and we won't guess their job from a name.
Search-search_rulings
This name is on the directory's tool list, but Trellis's technical documentation doesn't carry it in this form; it names a different tool instead. With no source behind it, this page gives it no role.
Search-search_attorneys
The directory publishes this name, and that's it. Trellis's technical documentation doesn't mention it and neither does any Claude page, so this page credits it with no capability of any kind.
What Claude checks with you first
By default, Claude stops and asks before every action it takes on an account for you. With Trellis, the sheet doesn't expose any action of that kind.
The 22 described tools look things up: Trellis states that none of them create, modify or delete data, and no source describes a confirmation specific to any of them. The two undocumented tools fall under the default rule. On Team and Enterprise workspaces, owners can restrict what the connector may do across the org and decide whether a member can let some actions through without being asked again.
Which plans include it
None of the 819 sheets in the official directory shows plan availability, and nobody publishes it connector by connector.
Anthropic's general rule is that remote connectors are open to all users on Claude, Cowork, Claude Desktop and mobile. On Team and Enterprise, an Owner or Primary Owner first switches the connector on for the org. On Trellis's side, usage depends on your account with the publisher, separately from Claude. For the current status, check the Trellis sheet in the official directory.
Where this connector stops
A connector isn't an automation. Claude calls these tools while it answers you, so nothing fires when a new ruling comes down.
Only Trellis documents this connector, in its technical documentation; neither Claude's help center nor Anthropic's docs mention it. Even with Trellis's statement, a sheet that shows only reading is an observed floor, not a guarantee, since an admin can open more than a public sheet lists. The partner badge isn't a security audit, and Anthropic notes on every sheet that it doesn't pick a publisher's tools or vouch for how they behave.
