Install

Fuse is a .NET global tool. Install it once and the fuse command is available in any terminal.

dotnet tool install -g Fuse

Verify the install:

fuse --help

Requirements

• The .NET SDK 10.0 or later. No other dependencies are required for the command-line tool.
• Git change scoping additionally needs the git executable on your PATH.

Update

dotnet tool update -g Fuse

Run without installing

The .NET 10 SDK can run a tool on demand without a global install using dnx:

dnx Fuse -- serve

This is handy for trying the MCP server or pinning a one-off run to a specific version.

Build from source

On Windows, the bundled script builds, packs, and installs the tool locally:

install.bat

On any OS, pack the CLI project and install from the local package:

dotnet pack src/Host/Fuse.Cli/Fuse.Cli.csproj -c Release
dotnet tool install -g Fuse --add-source src/Host/Fuse.Cli/nupkg

The pack step produces a NuGet package under the project's nupkg directory, and the install command adds it as a source.
