mcp-server-git: when performing git-add, it seems that git config is ignored

Desciption
When performing the git add command from terminal line, the changes are correctly identified and added for future commit. If a single line is added to a file, only that line is recognised as a change and added for later commit.
However if the git-add is performed via the mcp-server-git, all the line endings are modified (in particular, a special character ^M is added at the end of each line of the added files). My guess is that Mcp-server-git is not taking into account the git config in my machine (in particular, the config that avoids bad behaviours with line endings, git config --global core.autocrlf true).

To Reproduce
Steps to reproduce the behavior:

1. I am using Windows 11 Enterprise (version 24H2). In order to test the MCP server, I installed it with Python (pip install mcp-server-git) and I use it from the GitHub Copilot plugin inside IntelliJ (version of the plugin 1.5.44.10400-243). All this stack just to simplify my activities, it should not affect the result with the MCP server itself.

2. I made a change (edited one line) in the codebase then asked Copilot to perform a git-add, the proposed command is a simple git add with the following parameters:
   { "files": [ "src/main/resources/application.properties" ], "repo_path": "c:\\my_project" }
   However, when checking with an external tool what has been done (SourceTree, in my case) I see that all the lines have actually changed. Looking further, I see that all the lines now end with "^M" character

3. Unstaging the file then doing the same git add src/main/resources/application.properties from the terminal, only my edited line is recognised as changed and staged for commit, as it should be

Expected behavior
The mcp-server-git/mcp-server-git_git_add command should perform exactly the same as the git add command in the terminal. In particular, I expect the MCP server command to use my git config

Logs
I don't have useful logs and actually I'm not able to collect them. If needed, please explain how I can collect them.

Start with the mcp-server-git_git_add command and compare its behavior with git add from a terminal on Windows 11. Reproduce the case using core.autocrlf true and src/main/resources/application.properties, then verify that only the edited line is staged and no line endings are changed.
