Features

This MCP server provides the following tools:

list_commits

List recent commits in the repository.

Parameters:

• count (number, optional): Number of commits to list (1-100, default: 10)
• cwd (string, optional): Working directory (default: current directory)

Returns:

{
  "commits": [
    {
      "hash": "full commit hash",
      "shortHash": "short hash",
      "message": "commit message",
      "author": "author name",
      "date": "commit date"
    }
  ]
}

get_repo_status

Check the current repository status.

Parameters:

• cwd (string, optional): Working directory

Returns:

{
  "branch": "current branch name",
  "isClean": true,
  "hasUncommittedChanges": false,
  "isRebaseInProgress": false
}

preview_rename

Preview commit message changes without actually applying them.

Parameters:

• commit_hash (string, required): Commit hash to rename (full or short)
• new_message (string, required): New commit message
• cwd (string, optional): Working directory

Returns:

{
  "commit": {
    "hash": "commit hash",
    "shortHash": "short hash",
    "currentMessage": "current message",
    "newMessage": "new message",
    "author": "author",
    "date": "date"
  },
  "canProceed": true,
  "warnings": ["warning messages"]
}

rename_commit

Actually rename a commit message. Warning: This rewrites Git history!

Parameters:

• commit_hash (string, required): Commit hash to rename
• new_message (string, required): New commit message
• force (boolean, optional): Bypass safety checks (default: false)
• cwd (string, optional): Working directory

Returns:

{
  "success": true,
  "oldHash": "old hash",
  "newHash": "new hash",
  "newMessage": "new message",
  "warnings": ["warning messages"]
}

undo_rename

Undo the last commit message change using git reflog.

Parameters:

• cwd (string, optional): Working directory

Returns:

{
  "success": true,
  "message": "Successfully reverted to previous state using reflog"
}

Safety Features

This tool provides several safety mechanisms:

1. Working Directory Check: Refuses to operate if there are uncommitted changes
2. Rebase Status Check: Refuses to operate if a rebase is in progress
3. Remote Push Check: By default, prevents changing commits that have been pushed to remote (can be bypassed with force=true)
4. Preview Feature: See what will happen before making actual changes
5. Undo Feature: Revert changes using reflog if you make a mistake

Important Warnings

Renaming commits rewrites Git history!

• Only use on branches you work on alone
• Rewriting history on shared branches can cause serious problems
• After changing pushed commits, you'll need git push --force
• Always use preview_rename first to verify changes
