On 2026-05-12 Anthropic shipped a packaged legal vertical, and for an operator the interesting part isn't "Claude does law" โ it's the shape. Three pieces: 20+ MCP connectors into legal systems of record (iManage, NetDocuments, Relativity, Thomson Reuters CoCounsel, Everlaw, Ironclad, Docusign, Box, Datasite, Consilio), 12 practice-area plugins scoped to roles (Litigation, IP, Privacy, Corporate, Employment, Regulatory, AI Governance, Product, Commercial, plus Law Student / Legal Clinic / Legal Builder Hub), and discounted public-service pricing for legal aid. Design partners are not small: Thomson Reuters, Docusign, Harvey, Everlaw, Freshfields, Accenture, Holland & Knight. Claude Opus 4.7 scored 90.9% on Harvey's BigLaw Bench, the highest of any Claude model โ a procurement-grade number, the kind you put in a risk memo. The operator read: this is the connectors-plus-skills pattern this entire book teaches, assembled into a product and sold into a regulated industry. The signal is not the law vertical specifically โ it's that "MCP connectors into the systems of record + role-scoped plugins" is now Anthropic's own go-to-market motion. If you operate in or sell into any regulated niche, the move is to assemble that same shape yourself โ the connector layer over your systems of record, plus per-function skill packs โ before a vendor packages your niche for you. Verticalization is a tailwind for operators who already think in connectors and skills, and a clock for those who don't.
