Type the given text string at the current cursor position using simulated keystrokes. Requires Accessibility permissions for the terminal/app running the MCP server. Use click first to focus the target input field.
AI agents invoke type_text to trigger actions in MacWright. 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.
This tool simulates keyboard input at the current cursor position, which constitutes an external operation that can trigger arbitrary actions depending on context—submitting forms, executing commands in a terminal, entering credentials, etc. The effects are highly context-dependent and potentially irreversible (e.g., sending a message, running a command), making Execute the most appropriate category.

Attacks that exploit this kind of access
Type the given text string at the current cursor position using simulated keystrokes. Requires Accessibility permissions for the terminal/app running the MCP server. Use click first to focus the target input field. It is categorised as a Execute tool in the MacWright MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the MacWright MCP server in PolicyLayer and add a rule for type_text: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MacWright. Nothing to install.
type_text is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the type_text rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for type_text. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
type_text is provided by the MacWright MCP server (ruchit-p/macwright). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
