Go version mismatch is this expected?

$ /usr/bin/go install github.com/matlab/matlab-mcp-core-server/cmd/matlab-mcp-core-server@latest
go: github.com/matlab/matlab-mcp-core-server/cmd/matlab-mcp-core-server@latest (in github.com/matlab/[email protected]): go.mod:5: invalid go version '1.25.5': must match format 1.23
go.mod:7: unknown block type: tool

Hi @rvignesh, thanks for reporting this!

The error means your local Go installation is older than what the project requires. Our go.mod specifies go 1.25.5 and uses the tool directive (introduced in Go 1.24), so go install won't work with earlier Go versions.

You have two options:

Option 1 (recommended): Use a pre-built binary

Rather than building from source, you can download a ready-to-use binary from the latest release. We publish binaries for Windows, macOS (Intel & Apple Silicon), and Linux — no Go installation required.

Option 2: Upgrade Go

If you prefer building from source, update your Go installation to 1.25.5 or later from go.dev/dl, then retry the go install command.
