Allow your claws to do things remotely on a Desktop machine via MCP

Remote Claws — Remote Machine Control

Provide permission-based access to a remote desktop machine via the remote-claws MCP server (https://github.com/wentbackward/remote-claws) allowing your agent to run in a sandbox.

Four tools, each taking an action parameter: remote_browser, remote_desktop, remote_exec, remote_files. Read each tool's description for its action list — an unknown action returns the valid list.

CRITICAL: Remote vs Local

The remote_* tools act on the REMOTE machine. OpenClaw's built-in browser, exec, read/write/edit act on the LOCAL gateway machine. Never substitute one for the other. Take care not to confuse remote-claws with remote SSH commands.

Strategy

1. Screenshot first. remote_desktop(action="screenshot") before clicking or typing; use the returned coordinates to target actions. Re-screenshot after actions — windows move, dialogs appear.
2. Prefer remote_browser for web tasks. CSS selectors are resolution-independent. Only fall back to remote_desktop for things the browser can't reach (native dialogs, file pickers).
3. Prefer element names over coordinates. remote_desktop(action= "click_element", ...) targets controls by name — survives window moves.
4. Exec is async. remote_exec(action="run", ...) returns a process_id; poll with action="get_output" (wait=true blocks), action="send_input" for stdin, action="kill" when done.
5. Denied actions are final. A "permission denied" result means server policy — do not retry unless the user requests it.

Common actions

• Desktop: screenshot, mouse_click, mouse_move, mouse_drag, scroll, type_text (ASCII only), press_key, find_window, focus_window, list_elements, click_element, get_element_text
• Browser: navigate, click, fill (clears first, Unicode-safe), type (appends), press_key, get_text, get_html, eval_js, screenshot, wait_for, select_option, go_back, go_forward, tabs_list, tab_new, tab_close
• Exec: run, get_output, send_input, kill, list
• Files: read (base64, offset/limit for chunks), write (base64), list, delete, move, info

Authentication & Security

The remote-claws MCP server requires a bearer token, configured in openclaw.json when registering the server. Unauthenticated connections get 401. The server also supports IP allowlisting (allowed_ips), host header validation (allowed_hosts), and per-action permission policies (permissions.json). See the setup guide and README.

Important Notes

• Screenshots are JPEG, max 1280x960. Coordinates are absolute pixels. If your main LLM supports images, openclaw media handling should just work. Otherwise use remote_desktop(action="screenshot", save_to_disk=true) and download the binary.
• Reading Remote Files: remote_files(action="read", ...) returns base64 only up to a threshold. Bigger reads fail with "inline read would return N bytes" to avoid context token explosion. Re-issue the same read with as_url=true and use the returned URL to download — do NOT retry the plain read. Small chunks via offset/limit will work.
• type_text is ASCII only. For Unicode, use browser fill, or clipboard: remote_exec(action="run", command="powershell", args=["Set-Clipboard", ...]) then remote_desktop(action="press_key", keys="ctrl+v").
• The browser launches on first use and stays open across calls. Sessions persist (cookies, local storage).
