MAF v1 — Middleware and the Agent Pipeline (Python + .NET)
Use middleware to wrap agent runs, intercept tool calls, and redact PII before the LLM sees it in both Python and .NET safely.
Middleware
Error Handling and Exception Management in the API
An unhandled exception in a default ASP.NET Core API gives the client an empty 500 and gives you a stack trace in a log nobody is watching. The only thing worse is the API that returns the stack trace to the caller. The Contact Management Application takes the middle path: one middleware catches everything, maps known exception types to sensible status codes, returns a predictable JSON shape, and logs the details server-side. This post walks through that implementation and where I would lean on the newer built-in alternatives instead.
