# ui_get_element Re-resolves a previously returned element_ref (its bounds/state may have changed). Returns role, label, bounds, enabled, focused, value. stale_element if the handle is unknown or the element no longer exists. Agent View of the PolicyLayer registry record for `ui_get_element`. HTML page: https://policylayer.com/tools/com-local-mcp-local-mcp/ui-get-element ## Facts - Tool: `ui_get_element` - Server: Local (`local-mcp`) — https://policylayer.com/tools/com-local-mcp-local-mcp.md - Install: `npx -y local-mcp` - Homepage: https://github.com/lanchuske/local-mcp - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server auth posture: open - Server CORS policy: * - Server rate-limited: no - Parameters: 1 (1 required) - Recommended policy verdict: Allowed ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `element_ref` | string | yes | | Parameters from the server's own tool schema. ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "ui_get_element", "arguments": { "element_ref": "" } } } ``` ## Why ui_get_element is rated Low This is a pure read operation that queries UI element state without side effects. It supports other tools (like chrome_click or chrome_fill_form) by providing reference data, but performs no actions itself. The low severity reflects minimal risk even if misused—an attacker gains only visibility into UI structure and state, not control or data access. From the tool's own definition: "The tool 'ui_get_element' retrieves element properties (role, label, bounds, enabled, focused, value) with no modification capability. Description explicitly states it 're-resolves' and 'returns' data, with error handling for stale elements." ## Use case AI agents call ui_get_element to retrieve information from Local without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Local: ```json { "version": "1", "default": "deny", "tools": { "ui_get_element": {} } } ``` ## Other tools on Local (233) - `delete_calendar_event` — Destructive — https://policylayer.com/tools/com-local-mcp-local-mcp/delete-calendar-event.md - `delete_reminder` — Destructive — https://policylayer.com/tools/com-local-mcp-local-mcp/delete-reminder.md - `delete_reminder_list` — Destructive — https://policylayer.com/tools/com-local-mcp-local-mcp/delete-reminder-list.md - `m365_delete_event` — Destructive — https://policylayer.com/tools/com-local-mcp-local-mcp/m365-delete-event.md - `onedrive_delete_file` — Destructive — https://policylayer.com/tools/com-local-mcp-local-mcp/onedrive-delete-file.md - `recipe_delete` — Destructive — https://policylayer.com/tools/com-local-mcp-local-mcp/recipe-delete.md - `chrome_click` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/chrome-click.md - `chrome_evaluate_js` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/chrome-evaluate-js.md - `chrome_fill_form` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/chrome-fill-form.md - `chrome_go_back` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/chrome-go-back.md - `chrome_navigate` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/chrome-navigate.md - `chrome_type` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/chrome-type.md - `chrome_wait_for` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/chrome-wait-for.md - `nordvpn_diagnose` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/nordvpn-diagnose.md - `notion_open_page` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/notion-open-page.md - `recipe_run` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/recipe-run.md - `run_diagnostics` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/run-diagnostics.md - `run_terminal_command` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/run-terminal-command.md - `safari_click` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/safari-click.md - `safari_evaluate_js` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/safari-evaluate-js.md - `safari_fill_form` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/safari-fill-form.md - `safari_go_back` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/safari-go-back.md - `safari_navigate` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/safari-navigate.md - `safari_query_selector_all` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/safari-query-selector-all.md - `safari_type` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/safari-type.md - `safari_wait_for` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/safari-wait-for.md - `screen_record_start` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/screen-record-start.md - `screen_record_stop` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/screen-record-stop.md - `setup_install` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/setup-install.md - `ui_click` — Execute — https://policylayer.com/tools/com-local-mcp-local-mcp/ui-click.md - …and 203 more: https://policylayer.com/tools/com-local-mcp-local-mcp.md ## For agents This record is a snapshot.
