CodeReach
Which endpoints and jobs reach this code, and what does your diff affect.
CodeReach is an MCP server for ASP.NET Core and C# solutions. It loads your solution with Roslyn, builds a call graph from the compiler's own semantic model, keeps it on disk, and answers questions an agent (or you, from a shell) would otherwise answer with grep and guesswork:
- What calls this method, through its interface, all the way up to a controller action, a minimal API handler or a background service?
- Which endpoints exist, with their full route and authorization, including your own permission attributes?
- I changed these lines. Which endpoints and jobs does that touch?
Status: 0.1.0, not yet published to NuGet. The commands below that use dnx work once it is.
Why not grep, or a tree-sitter index
