What you get from it
Practical testing not documented.
LinkLoot assessment · not a user rating.
Microsoft Foundry Toolkit brings model discovery, prompt-agent building, hosted-agent deployment, MCP tool integration, and Agent Inspector workflows into VS Code. The 1.6.14 release adds solution templates, skill-only toolboxes, active hosted-agent response controls, broader model choices, and generally available Agent-to-Agent connections.
What it is useful for
- Prototype prompt agents and compare models without leaving VS Code.
- Create toolboxes that combine skills and tools, including MCP integrations.
- Inspect hosted-agent responses, traces, tool calls, and continuation behavior while debugging.
- Start from reference solution templates with a generated README.
Access and caveats
The Marketplace listing says initial model experiments can use GitHub-hosted models without an Azure subscription. Managed Foundry projects, hosted-agent deployment, production evaluation, and tracing require the relevant Microsoft/Azure setup and permissions. Microsoft also states that the extension collects usage data; review its telemetry and privacy settings before adopting it in a sensitive workspace.
