ClearUvxCache turns uvx.exe into uvx.ex on Windows

[MyNameisPI]

Description

In ServerManagementService.ClearUvxCache and ExecuteUvCommand, the code derives uv from uvx like this:

string uvxPath = MCPServiceLocator.Paths.GetUvxPath();
string uvCommand = uvxPath.Remove(uvxPath.Length - 1, 1);

On Windows, when GetUvxPath() returns ...\uvx.exe, this becomes ...\uvx.ex, which is invalid and causes the cache clear command to fail.

Suggested Fix

Build the uv path using the file name and extension instead of removing the last character:

var dir = Path.GetDirectoryName(uvxPath);
var ext = Path.GetExtension(uvxPath); // ".exe" or ""
var uvPath = Path.Combine(dir ?? string.Empty, "uv" + ext);

This works for both uvx and uvx.exe and avoids producing uvx.ex.

Environment

• OS: Windows
• Unity MCP package version: 8.1.5
