The collaboration will begin with Claude’s integration into IBM’s new AI-first integrated development environment (IDE), currently available in private preview to select clients. IBM reported that over 6,000 early adopters within the company are already using the new IDE, achieving productivity gains averaging 45%. The IDE is specifically designed for enterprise software development lifecycles, including application modernization, code generation and review, end-to-end orchestration, and security-first development processes.

As part of the partnership, IBM created and Anthropic verified a guide titled “Architecting Secure Enterprise AI Agents with MCP,” which focuses on the Agent Development Lifecycle for designing and managing enterprise AI agents. This integration aims to enhance productivity for IBM’s clients by embedding Claude into both internal and external development tools and enterprise-level products.
