Verified in the Claude Connector Directory. On Claude Team and Enterprise, an organization owner can add the connector, and each member connects an individual Descrybe account.
Legal Research Toolkit
Combine Claude’s reasoning with primary law you can inspect.
Descrybe provides the research capabilities. Claude provides the environment where you ask, refine, and use the result.
Check what supports the answer
Resolve citations, retrieve focused source passages, verify quoted language, and inspect the authorities behind the analysis.
Review treatment and citing cases
Research how later courts have treated an authority and find the citing decisions that matter to the issue.
Legal workflow ideas
Ask for the outcome—not just a case search.
These examples show what becomes possible when the surrounding assistant or application combines its own reading, reasoning, and work-product capabilities with focused Descrybe tools. They are ideas for use rather than separate product modes; the exact sequence and available steps depend on the host, its settings, and the context you choose to provide.
Everyday idea
Plan a complex research question
Have Claude turn a broad legal question into a research plan, surface the facts and jurisdiction it still needs, and organize the strongest cases and non-case primary law on both sides.

Everyday idea
Review a long brief or memorandum
Give Claude a brief or memorandum and ask it to organize a source review: extract and resolve its cases, verify quotations, inspect treatment, and find later citing decisions. For a structured review report, use Descrybe Review in the Platform.

Everyday idea
Search by facts, not just keywords
Describe the legal issue and the factual pattern—even an unusual one—and let Claude combine conceptual and exact-language searches to identify supporting and contrary cases worth deeper review.

Everyday idea
Synthesize a case and its later history
Build a focused case note from the decision’s issues, holding, reasoning, key passages, treatment, and later citing cases. Claude can organize the analysis while Descrybe supplies targeted source material.

Advanced idea
Stress-test a legal proposition
Ask Claude to test a proposition rather than merely support it: find the authority and language that supports, narrows, distinguishes, or contradicts the proposition and explain the resulting limits.

Develop both sides of an argument
Provide the facts, goal, forum, and procedural posture. Claude can research competing positions, assemble the strongest authorities and passages, and turn the result into an argument outline for lawyer revision.

Find the weak points in a brief
Have Claude stress-test a brief for vulnerable propositions, missing context, quotation problems, weak or unresolved citations, overlooked later cases, and contrary authority that deserves an answer.

Map issues across pleadings
Let Claude compare pleadings, organize claims and defenses, and map admissions, denials, and disputed issues across long documents. Descrybe can then research the governing law and inspect the cited authorities.

Research across a document collection
Use Claude’s document context to classify and summarize a legal document or project collection, answer questions grounded in those files, and use Descrybe to resolve and check the underlying legal authorities.

How it fits your work
Give Claude a purpose-built legal research layer.
- Work conversationally while Claude calls focused Descrybe research and verification tools.
- Inspect the request and result for individual tool calls inside Claude.
- Follow the returned citations and source links to review the underlying law yourself.
Your Claude access is managed separately from your Descrybe subscription.
