New MCP integration brings CoCounsel Legal into Claude workflows to help legal work meet fiduciary-grade standards

TORONTO, May 12, 2026 /CNW/ -- Thomson Reuters (TSX/Nasdaq: TRI), a global content and technology company, today announced a new Model Context Protocol (MCP) integration with Anthropic that connects Claude directly to CoCounsel Legal. Legal professionals can now move seamlessly between general-purpose AI and citation-grounded legal work, from either working environment. As MCP integrations proliferate across the legal market, Thomson Reuters is bringing something distinct: fiduciary-grade AI, our standard for accuracy, accountability and trust.

Adoption of legal AI continues to accelerate, alongside a widening gap between the speed and convenience of general-purpose AI and the accuracy and verifiability of professional-grade systems. CoCounsel Legal is designed to meet the standards of legal professionals, where almost right is not good enough. Now Thomson Reuters is bringing that industry standard to professionals working in Claude, making it possible to seamlessly move work between Claude and CoCounsel Legal's comprehensive, fiduciary-grade workflows.
