$npx -y @vukvukovich/hammerspoon-mcp@0.4.0 HS_MCP_TOOLS — Which tools to expose. "safe" (default) exposes inspection, window management, and system tools only. "all" additionally exposes hs_eval, hs_applescript, and hs_ui_press, which run arbitrary Lua and AppleScript and press UI elements - anything the user can do.
HS_MCP_TRANSPORT — How Lua reaches Hammerspoon. "socket" (default) keeps one persistent Unix domain socket, self-installed on first call, with automatic fallback to spawning; "spawn" runs one hs process per call.
HS_MCP_HS_PATH — Explicit path to the Hammerspoon hs command line tool. Only needed when Hammerspoon is installed somewhere unusual.
HS_MCP_DOCS_PATH — Explicit path to Hammerspoon's bundled docs.json, used by hs_api_search.
HS_MCP_LOG_LEVEL — Log verbosity on stderr: debug, info (default), warn, or error.
