About TokenSaver

What it is

TokenSaver is an open-source MCP (Model Context Protocol) server for .NET developers. It gives an AI coding assistant a token-efficient view of C#, Razor, and .NET project files using the Roslyn compiler platform, so the assistant reads the same code while spending far fewer tokens — with no loss of logic. Typical reduction is 50–95% on C# files.

Fewer tokens processed means lower cost, lower latency, and a smaller carbon footprint for AI-assisted development. This site is the live dashboard tracking how many tokens the tools have saved across all installs.

What the tools do

Outline — signatures of every type and member with no bodies, for "what's in this file?"
Focus — a named method or type with full bodies, plus signatures of what it references.
Trace — find what calls a method, implements an interface, or where a type is registered in dependency injection, across a whole project.
Map — index every type in a project to its file and base types, to locate code without knowing the file first.
Minify / Alias — lossless whole-file reduction, auto-dispatched by file extension.
