Month: 2025-10 — Delivered MCP integration across the Azure Developer CLI and extensions, enabling richer interactions with external tools through agent elicitation, MCP-related handlers, and scaffolding for AI Foundry integration and demo extension MCP server support. This work is complemented by the Extension Lifecycle, Artifact, and Architecture Enhancements, which upgraded the extension framework from alpha to beta, introduced artifact-based lifecycle (build, package, deploy), added extension providers, and alignment with azd artifacts. It also includes schema improvements (language optional) and an extensible type mapper to improve consistency and deployment automation. Reliability improvements address non-interactive scenarios, adding retry prompts for agents, improving test stability, and tightening event handling to avoid leaks via automatic cleanup. These changes collectively raise developer productivity, shorten time-to-value for customers, and enable a scalable, robust extension ecosystem within Azure Dev features.
