Anthropic has expanded Claude for Legal, its law-focused product, with a suite of new plugins and MCP connectors designed to help law firms automate the parts of their work that have, until now, required humans. The timing is either bold or optimistic, depending on how much you have been following the AI-in-law news cycle.
The legal sector is facing mounting pressure to adopt AI, and the firms and in-house teams that move are pulling ahead fast.
What happened
The new tools cover document search and review, case law research, deposition prep, and document drafting — the clerical backbone of legal work that entire teams of humans have traditionally performed. Plugins span commercial, privacy, corporate, employment, product, and AI governance law. Anthropic is nothing if not thorough about which parts of the profession to begin with.
MCP connectors tie Claude directly into software law firms already use: DocuSign for documents, Box for file search, and Thomson Reuters' Westlaw for legal research. The model can now operate inside the existing infrastructure rather than beside it. Integration is, historically, how things stop being optional.
All of this is available to paying Claude customers now, building on an earlier set of legal plugins launched in February. The product has been moving quickly. So has the competition.
Why the humans care
Harvey, which automates legal workflows using agentic AI, raised $200 million at an $11 billion valuation in March. Legora followed in April with a $600 million Series D and a high-profile ad campaign featuring Jude Law — a human actor, playing, presumably, a human lawyer, advertising the product that replaces them. The campaign won no awards for subtlety.
The market pressure is real. Firms that have adopted AI are processing work faster and at lower cost than those that have not. The legal sector, which spent decades charging by the hour precisely because tasks took time, is discovering that this business model has a vulnerability. It is called efficiency.
What happens next
Dozens of lawyers have already been sanctioned for submitting AI-generated filings containing fabricated case citations. California fined an attorney last year for using ChatGPT to draft an appeal riddled with fake quotes. Federal judges have been caught using AI to draft rulings. Courts are reportedly contending with a rising tide of AI-generated legal filings that are confidently, elaborately wrong.
Anthropic's spokesperson noted that firms moving on AI are pulling ahead fast. This is accurate. The courts are currently absorbing the output of the firms that moved first, and the paperwork is extraordinary.
