🛠️Morgan Stanley Modernizes API Program with CALM and MCP
Morgan Stanley's API overhaul with CALM and MCP
TL;DR
Morgan Stanley modernizes its API program with CALM and MCP, enabling zero-downtime upgrades and automated governance. Over 110 APIs now live, with security built into the protocol.
Morgan Stanley is modernizing its API program with Architecture as Code (CALM) and Model Context Protocol (MCP). This shift allows for zero-downtime platform upgrades and automated governance through deployment gates. Over 110 APIs are now live in production, with security and governance baked into the protocol, making it easier for developers to manage and scale their API infrastructure. The protocol introduces prompts and resources, enabling reusable, parameterized instructions and context for tasks.
Key Points
Morgan Stanley deployed over 110 APIs in production using Architecture as Code (CALM).
Model Context Protocol (MCP) connects LLM-based applications to tools and data, enabling structured operations.
MCP uses client-server interaction for discovering, invoking, and validating in the background.
Automated governance is enforced through deployment gates, ensuring secure and compliant API deployments.
Zero-downtime platform upgrades enable safe scaling of enterprise AI and agentic workflows.
Why It Matters
If you're managing a large API program, Morgan Stanley's use of CALM and MCP offers a blueprint for modernization. Over 110 APIs are now live with zero-downtime upgrades and built-in security. This approach simplifies governance and scaling, making it a must-watch for any enterprise architect.
