Thomson Reuters, a global content and technology company, recently announced an expanded partnership with AI firm Anthropic. Through a new Model Context Protocol (MCP) integration, its CoCounsel Legal platform is now directly connected to Anthropic’s general-purpose AI assistant, Claude. This means lawyers working within Claude can seamlessly tap into CoCounsel Legal’s authoritative legal content and workflows, completing everything from research to execution while maintaining the industry’s highest professional standards.
A key highlight of this integration is the introduction of fiduciary-grade AI—Thomson Reuters’ industry benchmark for accuracy, accountability, and trustworthiness. The next-generation CoCounsel Legal has been rebuilt on Anthropic’s Claude Agent SDK, enabling it to autonomously plan tasks, select tools, retrieve authoritative content from Westlaw and Practical Law, and adjust in real time within workflows—ultimately delivering traceable, citation-backed legal outputs. David Wong, Chief Product Officer at Thomson Reuters, said: “We are turning CoCounsel Legal into the central system for legal work, connecting the tools lawyers use and meeting the professional standards they demand.”
