Tokensaver
by Byggarepopcommunityv1.7.2
An MCP server for .NET developers that provides token-efficient views of C#, Razor, VB.NET, and .NET project files using the Roslyn compiler platform. It also supports project-wide caller and implementor tracing for C# code.
From the registry: Token-efficient C#, Razor, and .NET file views for AI assistants. 50-95% token reduction via Roslyn.
Install & configure
Prerequisites
- required.NET 10 SDK or laterRequired if using the documented `dotnet tool execute` install path. The README notes that if `dotnet tool execute` is not recognized, you need .NET 10 SDK or later.https://dotnet.microsoft.com/download
Install in your client
Paste into the AI you're chatting with — it will figure out the rest
Please install the `tokensaver` MCP server into my current AI client (that's you).
Required prerequisites (do these first if not already done):
- **.NET 10 SDK or later** — Required if using the documented `dotnet tool execute` install path. The README notes that if `dotnet tool execute` is not recognized, you need .NET 10 SDK or later. (https://dotnet.microsoft.com/download)
Canonical MCP server config (stdio transport):
- command: `dotnet`
- args: ["tool","execute","TokenSaver.Mcp","--yes"]
- required environment variables:
- `TOKENSAVER_API_URL`: Base URL for the TokenSaver API/service used by the MCP server. The README’s documented configuration sets this explicitly. (example: `<your-tokensaver-api-url>`)
Note: The README provides client-specific wrappers for Cursor and Claude Desktop, but the canonical stdio shape is `dotnet tool execute TokenSaver.Mcp --yes` with `TOKENSAVER_API_URL` set. It also documents a universal fallback installation path (`dotnet tool install -g TokenSaver.Mcp` followed by `tokensaver-mcp register`) for writing configs automatically, but that is a setup workflow rather than the canonical config shape.
Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.Note: The README provides client-specific wrappers for Cursor and Claude Desktop, but the canonical stdio shape is `dotnet tool execute TokenSaver.Mcp --yes` with `TOKENSAVER_API_URL` set.
