Since the v2 cutover: code coverage for your AL test runs, running a snippet of AL without writing a codeunit for it, a watch mode that no longer reports fake failures mid-save, and about 130 fixes to places where the runner's behavior didn't match real BC. Plus shoutouts to the two AL developers whose bug reports drove most of them.
An MCP server that gives an AI coding agent — or you — grounded access to the actual Business Central Base Application source, across versions and countries, with every result verified against the real file.
v1 worked for the use cases it was built for. Companies actually using it told me that wasn't enough — most real extensions can't be unit tested at all without running against real Microsoft or ISV code. That feedback drove a clean v2 cut. It also changed how the runner fails: anything it can't support now throws loudly instead of quietly passing.
A standalone CLI tool that transpiles your AL source to C#, rewrites BC runtime types to in-memory mocks, and executes your test codeunits in seconds — no container, no SQL Server, no license required.
Fixing silent failures in the BC Code History pipeline, then cutting daily runs from 4–5 hours to under 90 minutes with partial ZIP downloads via HTTP Range requests.
