Glass.NET is a free .NET decompiler built around navigation — you open an assembly and read it like your own source. But plenty of the work you do with a decompiler isn't interactive at all. You want to gate a CI job on whether a dependency changed its public surface, emit a software bill of materials for every binary you ship, or check that the NuGet package you just pulled is really what it claims to be. And increasingly you want your AI coding assistant to answer "what does this dependency actually do?" without you hand-feeding it decompiled snippets.

Glass.NET 1.3.0 covers both. It adds a headless CLI — the same ICSharpCode.Decompiler engine as the UI, no window required — and glass mcp , a Model Context Protocol server that lets an AI assistant open assemblies and read decompiled C# on your behalf. Everything below is strictly static analysis : Glass reads metadata and IL and reconstructs C#. It never runs the assembly it inspects.…
