Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| LCU_HOME | No | Where the installer puts the server. Defaults to ~/.linux-computer-use. | ~/.linux-computer-use |
| LCU_DATA_DIR | No | Where the lease file and the audit log are written. Defaults to ~/.linux-computer-use. | ~/.linux-computer-use |
| LCU_IRREVERSIBLE | No | Replaces the list of verbs treated as irreversible, comma separated. | |
| LCU_PLAYWRIGHT_CLI | No | Path to an alternative playwright-cli, used instead of the bundled one. |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| openA | Open a browser session, or attach to a browser already running with a CDP endpoint. Call this first. |
| gotoC | Navigate the current tab to a URL. |
| snapshotA | Accessibility tree of the page with a ref for each element. Use these refs with click and fill. Prefer this over screenshot for acting: it is exact and cheap. |
| screenshotA | Image of the page. Use it to read visual content, verify a result, or work out coordinates for the mouse tool. |
| clickA | Click an element by its ref from snapshot. Blocked when the element looks irreversible unless confirm is true. |
| typeA | Type text into the focused element. Refused when a password field has focus. |
| fillB | Fill a field identified by its ref. Refused on credential fields. |
| pressB | Press a key, for example Enter, Tab or ArrowDown. |
| mouseA | Coordinate based mouse control for canvas, maps and custom widgets that have no accessible element. Take a screenshot first to read the coordinates. |
| tabsB | List, open, select or close tabs. |
| historyC | Go back, go forward or reload. |
| statusA | Report the session, the mode and who holds the control lease. Pass takeover: true to hand control to the human before they act in the dashboard. Control comes back only when the human releases it on their machine, never through this tool. |
| set_modeA | normal asks before sensitive actions. auto runs a complete objective end to end, stopping only for an empty login, an account choice, or an irreversible action. |

Scored across 13 tools
Most tools have clearly distinct purposes: goto for navigation, snapshot for accessibility tree, screenshot for visual capture, click/type/fill/press for input. The overlaps between click and mouse (ref vs coordinates) and type vs fill (focused vs by ref) are clarified by descriptions, making misselection unlikely.
Tool names are all lowercase and mostly single words, but they mix verb forms (goto, click, type, fill, press, open) with noun forms (snapshot, screenshot, mouse, tabs, history, status). The only underscore in set_mode breaks the otherwise uniform style, creating a minor inconsistency.
13 tools is well within the ideal range for a browser automation server. Each tool covers a distinct aspect of interaction, from session management and navigation to reading state and performing actions, without feeling bloated or sparse.
The toolset covers the core lifecycle: open, navigate, inspect (snapshot/screenshot), interact (click/type/fill/press/mouse), manage tabs/history, and control session mode. Minor gaps like an explicit wait or scroll tool are workable because snapshot can serve as a synchronization point and mouse can handle scrolling.
