Environment variables to set
BUN_UIA_PROFILECapability profile: 'readonly' (inspect/read only), 'safe' (read + input + window — default), or 'full' (also os + fs tools).
BUN_UIA_OSSet 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_ALLOWComma-separated tool names or categories to additionally allow on top of the profile.
BUN_UIA_DENYComma-separated tool names or categories to deny, overriding the profile and BUN_UIA_ALLOW.
BUN_UIA_CURSORSet 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_ROOTSandbox root directory that read_file/write_file/list_dir are confined to when fs tools are enabled.

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
