hypruse

How to start

1. Run the command in your terminal, in the project where you want it.
2. Sign in if asked the first time Claude connects.
3. Check it: run /mcp in Claude Code and look for it in the list.

What it needs

• HYPRUSE_SCREENSHOT_MODEOptional. How captures are returned: 'file' writes to XDG_RUNTIME_DIR and returns the path, 'image' returns the image inline. Use 'image' for clients that render MCP images but cannot read files, such as Claude Desktop.
• HYPRUSE_READONLYOptional. Set to 1 to expose only the observation tools (desktop, screenshot, zoom, ui, marks, binds, wait_for). The agent can see and narrate but cannot click, type, or launch.
• HYPRUSE_CONFINEOptional. Restrict input to a scope of windows and refuse everything outside it: 'launched' (only windows hypruse opened this session), 'class:firefox,kitty', or 'workspace:3,special:notes'. Unset means no confinement.
• HYPRUSE_AUTH_GUARDOptional. Refuse to click or type into system authentication dialogs (polkit, keyring prompts). On by default; 'strict' also refuses password fields in ordinary windows; 0 disables it.
• HYPRUSE_STRICTOptional. Set to 1 to refuse to act when the cursor or focused window moved since hypruse's last action, so the agent must re-read the desktop before retrying.
• HYPRUSE_MARKOptional. Set to 1 to make the agent's presence legible: tag every window it opens 'hypruse-owned' and flash an on-screen notice when it opens a window or captures the screen.
• HYPRUSE_CLIPBOARDOptional. Set to 1 to register the opt-in clipboard tool (never in read-only mode). Off by default because clipboards hold passwords.
• HYPRUSE_JOURNALOptional. Record every tool call, refusals included, as one NDJSON line: 1 writes to XDG_STATE_HOME/hypruse/journal.ndjson, or give a path. Read it back with 'hypruse journal'. Off by default.
• HYPRUSE_JOURNAL_MAX_BYTESOptional. Rotate the journal once it reaches this size, keeping one previous generation alongside it. Set 0 to never rotate.
• HYPRUSE_JOURNAL_TEXTOptional. Set to 1 to record typed and copied text in the journal verbatim instead of as a length plus digest. Off by default because keystrokes are passwords; needed only to replay typing.
• HYPRUSE_DRYRUNOptional. Set to 1 for a rehearsal: every acting tool validates its arguments and runs every trust guard, then reports what it would have done and delivers no input.
