Morgan Stanley uses CALM Architecture-as-Code to integrate MCP and A2A into its API program
At QCon London, Morgan Stanley engineers Jim Gough and Andreea Niculcea demonstrated how the firm has modernized its API program using an Architecture-as-Code approach called CALM, integrating the Model Context Protocol (MCP) and Agent-to-Agent (A2A) communications. They showed demos of MCP-enabled flows, automated governance via deployment gates, and zero-downtime platform upgrades to scale agentic workflows and production APIs (over 110 APIs deployed to date).
