Implementation Reference
- Core implementation of git_log tool: fetches recent commits using gitpython Repo.iter_commits and formats commit details (hash, author, date, message).
async def log(self, repo_path: str, max_count: int = 10) -> str: """Show git commit history.""" repo = git.Repo(repo_path) commits = list(repo.iter_commits(max_count=max_count)) log = [] for commit in commits: log.append(f"Commit: {commit.hexsha}\nAuthor: {commit.author}\nDate: {commit.authored_datetime}\nMessage: {commit.message}\n") return "\n".join(log) - Pydantic model defining input schema for git_log tool: repo_path (required) and optional max_count (default 10).
class GitLog(BaseModel): repo_path: str max_count: int = 10 - src/mcp_server_code_assist/server.py:131-135 (registration)Registers the git_log tool in the MCP server.list_tools() with name, description, and input schema.
Tool( name=CodeAssistTools.GIT_LOG, description="Shows git commit history", inputSchema=GitLog.model_json_schema(), ), - Handler dispatch in server.call_tool(): parses arguments into GitLog model and delegates to git_tools.log.
case CodeAssistTools.GIT_LOG: model = GitLog(repo_path=arguments["repo_path"], max_count=arguments.get("max_count", 10)) result = await git_tools.log(model.repo_path, model.max_count) return [TextContent(type="text", text=result)] - Factory function to get singleton GitTools instance, used by server to invoke git_log.
