search_files
Search for files by name pattern within directories, including subdirectories, while respecting .gitignore and excluding hidden items.
Instructions
Search for files by name pattern in a directory recursively.
Args: dir (str): Directory to search in (absolute or relative to allowed directories) pattern (str): Glob-style pattern to match file names (e.g., '.py', 'test_') exclude (str, optional): Glob-style pattern to exclude file names
Returns: List[str] | str: List of matching absolute file paths, or error message if failed
Note: - Directory must be within allowed directory roots - Searches recursively through subdirectories - Respects .gitignore files, and ignores hidden files and folders - Returns list for successful searches, string for errors

Implementation Reference
- main.py:461-498 (handler)The core handler function for the 'search_files' MCP tool. It is decorated with @mcp.tool, which registers it automatically with the name 'search_files'. The function performs recursive file search using glob patterns, respects .gitignore via _skip_ignored, applies exclusions, and operates only within allowed directories using _resolve. Returns list of matching paths or error string.@mcp.tool def search_files(dir: str, pattern: str, exclude: str | None = None) -> List[str] | str: """Search for files by name pattern in a directory recursively.
