Implementation Reference
- src/mcp_server_git/server.py:86-88 (handler)Core handler function that computes the git diff against the specified target using repo.git.diff(target). Called by the MCP tool dispatcher.
def git_diff(repo: git.Repo, target: str) -> str: return repo.git.diff(target) - src/mcp_server_git/server.py:28-30 (schema)Pydantic input schema for the git_diff tool, defining repo_path and target parameters.
class GitDiff(BaseModel): repo_path: str target: str - src/mcp_server_git/server.py:186-190 (registration)Registration of the 'git_diff' tool (GitTools.DIFF) in the list_tools() method, including name, description, and input schema.
Tool( name=GitTools.DIFF, description="Shows differences between branches or commits", inputSchema=GitDiff.schema(), ), - src/mcp_server_git/server.py:299-304 (handler)MCP call_tool dispatcher case for git_diff: extracts target, calls git_diff helper, formats and returns TextContent response.
case GitTools.DIFF: diff = git_diff(repo, arguments["target"]) return [TextContent( type="text", text=f"Diff with {arguments['target']}:\n{diff}" )] - src/mcp_server_git/server.py:63-75 (helper)Enum definition providing the tool name constant GitTools.DIFF = "git_diff" used in registration and dispatch.
