 ### Standalone tools
 
-- `computer_action` - Mouse, keyboard, and screenshot controls for browser sessions (click, type, press_key, scroll, move, get_position, screenshot).
+- `computer_action` - Mouse, keyboard, clipboard, and screenshot controls for browser sessions (click, type, press_key, scroll, move, get_position, read_clipboard, write_clipboard, screenshot).
+- `browser_curl` - Send HTTP requests through an existing browser session's Chrome network stack.
 - `execute_playwright_code` - Execute Playwright/TypeScript code against a browser with automatic video replay and cleanup.
 - `exec_command` - Run shell commands inside a browser VM. Returns decoded stdout/stderr.
 - `search_docs` - Search Kernel platform documentation and guides.
 
 ## Resources
 
-- `browsers://` - Access browser sessions (list all or get specific session)
