Tool-Approval

Microsoft Agent Framework’s latest releases, Python 1.10.0 (June 30) and .NET 1.12.0 (July 2), change a security default that’s easy to miss in the changelog: agent tools and file access now require approval unless you opt out. Both land as breaking changes.

Use middleware to wrap agent runs, intercept tool calls, and redact PII before the LLM sees it in both Python and .NET safely.
