type_text · MCP Tauri Automation MCP: Risk & Policy

WHAT IT DOES

What type_text does on MCP Tauri Automation

AI agents invoke type_text to trigger actions in MCP Tauri Automation. 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.

WHY IT NEEDS A POLICY

Why type_text needs a policy

This tool interacts with UI elements by typing text into them, which is an active browser/desktop automation action that triggers external operations on a running application. It goes beyond reading or simple data writing — it executes UI interactions in a Tauri desktop app context.

type_text Rate-limited

type_text stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
