1. app_closeCan change things

   Close one visible WebMCP Computer app window by process PID. Use a PID returned by app_open or app_list. Returns the closed PID and app ID; throws if that process does not exist.

   First seen 11 Oct 2026. Unchanged since.

2. app_listReads only

   List every running WebMCP Computer app window and its PID, rectangle, z-index, focus state, and minimized state. Use before targeting a window by PID. Returns an explicit note when no apps are open.

   First seen 11 Oct 2026. Unchanged since.

3. app_openCan change things

   Open a built-in WebMCP Computer app in a visible window. Optionally set x, y, width, height, and focus (default true); focus=false preserves current focus and places a new window below the focused window. Geometry uses the same work-area clamping as window_move and window_resize. Settings, Notes, and Preview are singletons: reopening one applies supplied placement to its existing window and return

4. browser_openCan change things

   Open the singleton Browser window and start one visible shared Cloudflare Chrome session. Optionally navigate to an http/https URL and set x, y, width, height, and focus like app_open. Reopening focuses the existing window and navigates it when url is supplied. Returns PID, current URL, fifteen-minute idle lifetime, and whether the window was reused. Session or rate-limit failures use 'webmcp-comp

5. cloud_execCan change things

   Visibly execute one command in the WebMCP Computer cloud container when the cloud kernel is active. Returns exitCode, stdout, stderr, pushed, pulled, and truncated after ordered output appears in Terminal; stdout and stderr are each capped at 256 KB. cwd defaults to /workspace and must stay below it; timeoutMs defaults to 300000 and caps at 600000. node_modules is container-only and is lost when t

   First seen 11 Oct 2026. Unchanged since.

6. fs_deleteCan change things

   Delete one file or directory tree from the shared WebMCP Computer filesystem. The home root itself cannot be deleted.

   First seen 11 Oct 2026. Unchanged since.

7. fs_editCan change things

   Replace exact text in one UTF-8 file. old_string must be a unique anchor unless replace_all=true; if it matches zero or multiple times, the error tells you to choose a longer anchor. Returns the normalized path and replacement count.

   First seen 11 Oct 2026. Unchanged since.

8. fs_listReads only

   List direct children of one ~-rooted WebMCP Computer directory. Returns sorted directories first, then files, with type, size, and modification time.

   First seen 11 Oct 2026. Unchanged since.

9. fs_mkdirCan change things

   Create one directory at a ~-rooted path. Parent directory must already exist.

   First seen 11 Oct 2026. Unchanged since.

10. fs_moveCan change things

    Move or rename one file or directory between two ~-rooted paths. Destination parent must exist and destination must be absent unless overwrite=true is passed; overwrite defaults to false.

    First seen 11 Oct 2026. Unchanged since.

11. fs_readReads only

    Read one UTF-8 text file from the shared WebMCP Computer filesystem by ~-rooted path. Text files only; content over 256 KB is truncated and `truncated: true` is set. Pass encoding="base64" to read any file as base64; oversized base64 output fails instead of being truncated.

    First seen 11 Oct 2026. Unchanged since.

12. fs_searchReads only

    Search text-file contents case-insensitively below a ~-rooted path, skipping binary files. Returns matching path, 1-based line number, and full line text, plus a truncated flag when max_results is exceeded.

    First seen 11 Oct 2026. Unchanged since.

13. fs_writeCan change things

    Create or replace one UTF-8 text file in the shared WebMCP Computer filesystem. Empty content truncates the file to zero bytes. Parent directory must exist; visible Files and Editor windows update live. Pass encoding="base64" to decode content and atomically write binary bytes.

    First seen 11 Oct 2026. Unchanged since.

14. killCan change things

    Terminate one WebMCP Computer app window or transient shell command by PID. PID 1 is protected. Returns the killed process record; throws when the PID does not exist.

    First seen 11 Oct 2026. Unchanged since.

15. machine_take_overCan change things

    Consequentially take machine ownership from another WebMCP Computer tab. This is the agent equivalent of the visible Take over control and is callable while this tab is blocked. The previous owner's local in-flight actions are rejected and cancellable transports are aborted. Remote work already accepted or completed may still finish and cannot be undone. Returns whether ownership changed.

    First seen 11 Oct 2026. Unchanged since.

16. os_manualReads only

    Start here when operating WebMCP Computer. Read its agent manual verbatim from ~/skills. Omit topic for the README and topic list, or request filesystem, terminal, windows, apps, preview, browser, cloud, or conventions.

    First seen 11 Oct 2026. Unchanged since.

17. os_publishCan change things

    Publish a text-only directory to a public internet URL and show that URL with a QR code. Published files are public and deleted after 30 days. Anonymous machines may successfully publish 20 times per 24-hour accounting window. path defaults to ~/site and must be a directory. Allows html, css, js, json, svg, txt, and md; maximum 64 files, 256 KB each, 2 MB total. This is consequential because anyon

    First seen 11 Oct 2026. Unchanged since.

18. os_searchReads only

    Search files by name and the first 256 KB of content plus apps, settings, running processes, and shell commands. Returns ranked rows ordered exact name, name prefix, then content, each with its acting verb and arguments. By default show=true displays those rows in Spotlight for about 3 seconds without taking focus; any human keypress or click dismisses it. Pass show=false for silent data-only sear

    First seen 11 Oct 2026. Unchanged since.

19. psReads only

    List the real WebMCP Computer process table: PID 1, open app windows, and transient running shell commands. Returns small records with PID, kind, command, and optional app or cwd.

    First seen 11 Oct 2026. Unchanged since.

20. screensaver_wakeCan change things

    Wake WebMCP Computer from its boot screensaver and reveal the desktop. Use when the idle screen is visible. Returns whether the screensaver was active before this call.

    First seen 11 Oct 2026. Unchanged since.

21. settings_getReads only

    Read all persisted WebMCP Computer settings from ~/.config/settings.json: theme, accent, CRT scanlines, verb hints, hostname, idle screensaver minutes, and cloud-kernel reboot preference.

    Visibly type and execute one just-bash command against the shared WebMCP Computer filesystem. Opens a Terminal when none exists; optionally target a terminal PID. Supports pipes, redirects, variables, subshells, jq, awk, sed, grep, and other bundled commands; network, Python, and JavaScript runtimes are disabled. Times out after 30s by default; timeout_ms can set up to 120s. Returns stdout, stderr

    First seen 11 Oct 2026. Unchanged since.

25. term_historyReads only

    Read structured command history from the live frontmost Terminal session, shared with the human and ordered oldest to newest. Defaults to 50 entries; pass term_pid to target another Terminal.

    First seen 11 Oct 2026. Unchanged since.

26. term_readReads only

    Read the last lines of an open WebMCP Computer Terminal's shared 2000-line scrollback. Defaults to the frontmost Terminal and 50 lines; returns the terminal PID, plain-text lines, and truncated when older scrollback was discarded.
