# ui_perform_action Find a UI element by locator (role + title/value) and perform an accessibility action on it. Agent View of the PolicyLayer registry record for `ui_perform_action`. HTML page: https://policylayer.com/tools/io-github-heznpc-iconnect/ui-perform-action ## Facts - Tool: `ui_perform_action` - Server: Iconnect (`iconnect-mcp`) — https://policylayer.com/tools/io-github-heznpc-iconnect.md - Install: `npx -y iconnect-mcp` - Homepage: https://github.com/heznpc/iConnect - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "ui_perform_action", "arguments": {} } } ``` ## Why ui_perform_action is rated High This tool drives UI automation by finding elements and performing accessibility actions (clicks, presses, etc.), which constitutes executing external operations. Misuse could trigger any UI action on the macOS system including activating destructive controls, submitting forms, or invoking system commands — making the blast radius high. From the tool's own definition: "'perform an accessibility action on it' — triggers UI interactions via accessibility APIs, executing arbitrary actions on UI elements based on role/title/value locators" ## Use case AI agents invoke ui_perform_action to trigger actions in Iconnect. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Iconnect: ```json { "version": "1", "default": "deny", "tools": { "ui_perform_action": { "limits": [ { "counter": "ui_perform_action_rate", "window": "minute", "max": 10, "scope": "grant" } ] } } } ``` ## Other tools on Iconnect (278) - `delete_contact` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/delete-contact.md - `delete_event` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/delete-event.md - `delete_note` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/delete-note.md - `delete_photos` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/delete-photos.md - `delete_playlist` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/delete-playlist.md - `delete_reminder` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/delete-reminder.md - `delete_reminder_list` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/delete-reminder-list.md - `delete_shortcut` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/delete-shortcut.md - `memory_forget` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/memory-forget.md - `move_note` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/move-note.md - `remove_from_playlist` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/remove-from-playlist.md - `semantic_clear` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/semantic-clear.md - `spotlight_clear` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/spotlight-clear.md - `trash_file` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/trash-file.md - `activate_tab` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/activate-tab.md - `ai_agent` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/ai-agent.md - `ai_chat` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/ai-chat.md - `ai_plan_metrics` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/ai-plan-metrics.md - `connect_bluetooth` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/connect-bluetooth.md - `disconnect_bluetooth` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/disconnect-bluetooth.md - `edit_shortcut` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/edit-shortcut.md - `event_subscribe` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/event-subscribe.md - `generate_image` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/generate-image.md - `generate_text` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/generate-text.md - `gws_raw` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/gws-raw.md - `import_shortcut` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/import-shortcut.md - `keynote_start_slideshow` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/keynote-start-slideshow.md - `launch_app` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/launch-app.md - `local_llm_generate` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/local-llm-generate.md - `minimize_window` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/minimize-window.md - …and 248 more: https://policylayer.com/tools/io-github-heznpc-iconnect.md ## For agents This record is a snapshot.
