Thomson Reuters CoCounsel Legal Next Generation Goes GA with MCP and Full Agentic Experience

Thomson Reuters launched the next generation of CoCounsel Legal on August 20 as a fully agentic AI experience — moving from research and issue analysis to trusted work product within a single workflow, grounded in Westlaw, Practical Law, and the organization's own knowledge. The release includes an expanded CoCounsel Legal MCP server with Claude, enabling legal professionals to access CoCounsel directly from Claude and receive cited, traceable work product; an AWS collaboration extending CoCounsel into Amazon Quick and other AWS offerings (via MCP); and a forthcoming Reveal integration bringing reviewed evidence directly into CoCounsel for research and drafting. For KM professionals, the agentic CoCounsel release means authoritative legal content — case law, statutory text, practical guidance — is now accessible as a governed context layer that agents can draw on alongside firm-specific knowledge, without requiring separate integration work by the firm's technology team.
