Implementation Reference

• src/mcp_server_code_assist/tools/file_tools.py:81-136 (handler)

  The core handler function for the 'file_tree' tool. Generates a directory tree visualization, optionally using git-tracked files or gitignore patterns to filter contents.
  async def file_tree(self, path: str) -> tuple[str, int, int]: """Generate tree view of directory structure. Args: path: Root directory path Returns: Tree view as string """ path = await self.validate_path(path) base_path = path # Try git tracking first tracked_files = self._get_tracked_files(path) gitignore = self._load_gitignore(path) if tracked_files is None else [] def gen_tree(path: Path, prefix: str = "") -> tuple[list[str], int, int]: entries = [] dir_count = 0 file_count = 0 items = sorted(path.iterdir(), key=lambda x: (x.is_file(), x.name)) for i, item in enumerate(items): rel_path = str(item.relative_to(base_path)) # Skip if file should be ignored if tracked_files is not None: if rel_path not in tracked_files and not any(str(p.relative_to(base_path)) in tracked_files for p in item.rglob("*") if p.is_file()): continue else: # Use gitignore if self._should_ignore(rel_path, gitignore): continue is_last = i == len(items) - 1 curr_prefix = "└── " if is_last else "├── " curr_line = prefix + curr_prefix + item.name if item.is_dir(): next_prefix = prefix + (" " if is_last else "│ ") subtree, sub_dirs, sub_files = gen_tree(item, next_prefix) if tracked_files is not None and not subtree: continue entries.extend([curr_line] + subtree) dir_count += 1 + sub_dirs file_count += sub_files else: if tracked_files is not None and rel_path not in tracked_files: continue entries.append(curr_line) file_count += 1 return entries, dir_count, file_count tree_lines, _, _ = gen_tree(path) return "\n".join(tree_lines)
• src/mcp_server_code_assist/tools/models.py:31-33 (schema)

  Pydantic schema/model defining the input for the file_tree tool: a path string.
  class FileTree(BaseModel): path: str
• src/mcp_server_code_assist/server.py:115-119 (registration)

  Tool registration in @server.list_tools(), defining name, description, and input schema for 'file_tree'.
  Tool( name=CodeAssistTools.FILE_TREE, description="Lists directory tree structure with git tracking support", inputSchema=ListDirectory.model_json_schema(), ),
• src/mcp_server_code_assist/server.py:191-194 (registration)

  Tool dispatch/execution handler in @server.call_tool() for 'file_tree', validating input with FileTree model and calling the file_tools.file_tree method.
  case CodeAssistTools.FILE_TREE: model = FileTree(path=arguments["path"]) result = await file_tools.file_tree(model.path) return [TextContent(type="text", text=result)]
• src/mcp_server_code_assist/server.py:25-25 (registration)

  Enum value definition for the 'file_tree' tool name in CodeAssistTools.
  FILE_TREE = "file_tree"
