Building AI agents sounds straightforward until you actually do it. You need an agent to onboard a new employee. It has to create an Entra ID account, provision GitHub access, spin up cloud resources, create tasks in Azure DevOps, and send a welcome message in Teams. Five tools. Five different authentication models. Five different teams are managing those tools. Now multiply that across every agent your organization is building. That’s the problem Microsoft is addressing with Toolboxes in Foundry, now available in public preview. What Toolboxes Actually Do A Toolbox is a named, reusable bundle of tools managed in Microsoft Foundry. You define your tools once, configure authentication centrally, and expose everything through a single MCP-compatible endpoint. Any agent that can consume an MCP endpoint can use a Toolbox — regardless of the framework it was built on. The endpoint looks like this: https://zava.services.ai.azure.com/api/projects/<project>/toolbox/<toolbox-na...
Microsoft has unveiled plans to incorporate Anthropic’s Claude Mythos Preview model and other AI models into its Security Development Lifecycle, embedding AI directly into the stages where code is written and tested. Rather than relying primarily on static analysis tools, Microsoft is adopting AI models capable of analyzing code dynamically and identifying complex vulnerabilities that might otherwise go undetected until later stages of development. Released on April 7, Anthropic’s Mythos model has already demonstrated a previously unmatched ability to uncover critical flaws across operating systems and widely used software. Anthropic claimed that the model’s ability to find security vulnerabilities is so advanced that it should not be released to the public. Microsoft gained access to the model through Anthropic’s Project Glasswing, a program that grants limited access to select tech firms for cybersecurity research. Within this framework, Microsoft is reporting measurable improve...
