Packages and local setup

The published npm package is bun-uia, version 1.9.1. Its declared MCP transport is stdio.

The package declares BUN_UIA_PROFILE: Capability profile: 'readonly' (inspect/read only), 'safe' (read + input + window — default), or 'full' (also os + fs tools).; BUN_UIA_OS: Set to '1' to allow OS-level tools (launch_app, run_program, open_path) AND filesystem tools (read_file, write_file, list_dir) regardless of profile.; BUN_UIA_ALLOW: Comma-separated tool names or categories to additionally allow on top of the profile.; BUN_UIA_DENY: Comma-separated tool names or categories to deny, overriding the profile and BUN_UIA_ALLOW.; BUN_UIA_CURSOR: Set to 'never' to forbid the real-cursor fallback entirely (strictly cursor-free). By default clicks/drags are cursor-free but fall back to the real hardware cursor when no cursor-free path exists.; BUN_UIA_FS_ROOT: Sandbox root directory that read_file/write_file/list_dir are confined to when fs tools are enabled..
