Nudge FAQs

Question 1

How does Nudge interact with macOS applications?

Accepted Answer

Nudge utilizes macOS accessibility APIs for sophisticated UI automation. It features advanced UI element management with an element registry and tree-based discovery, using direct AXUIElement references for maximum performance and reliability in controlling applications.

Question 2

Who is Nudge designed for?

Accepted Answer

Nudge is designed for two primary user groups: AI agents that require programmatic control over macOS applications via an MCP server, and Swift developers who want to integrate robust UI automation capabilities directly into their native macOS applications as a library.

Question 3

What are some core actions Nudge can perform?

Accepted Answer

Nudge provides tools to retrieve UI element trees (`get_ui_elements`), click specific UI elements by their ID (`click_element_by_id`), update UI element trees for deeper exploration (`update_ui_element_tree`), and set text in various UI text fields (`set_text_in_element`). It also handles auto-opening and focus management for applications.

Question 4

Does Nudge require special permissions to function?

Accepted Answer

Yes, Nudge requires accessibility permissions to be granted in macOS System Settings. Without these permissions, the server or your integrated application will not be able to interact properly with other macOS applications and will throw `accessibilityPermissionDenied` errors.

Question 5

What is Nudge and what does it do?

Accepted Answer

Nudge is a Swift-based toolkit that enables programmatic control and UI automation of macOS applications. It serves as an MCP (Model Context Protocol) server for AI agents and a direct Swift library for native applications, allowing interaction via macOS accessibility APIs.
