LeanLaw operates a remote Model Context Protocol server at https://api.leanlaw.io/mcp that lets an AI assistant work with a firm's clients, matters, time entries, expenses, fixed fees and invoices. It exposes the same operations as the REST API plus higher-level composite actions, is authorized per user via OAuth 2.1 against https://auth.myleanlaw.co/ with granular read/write scopes, and is in private beta enabled per firm on request.
