Type text character by character (simulates real keystrokes). Useful for search boxes and autocompletes that respond to individual key events.
AI agents invoke browser_type to trigger actions in Apple Shortcuts. 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 real keyboard input to interact with UI elements in a browser or application. It triggers external operations (UI interactions/keystrokes) whose effects depend on what text is typed and where — potentially filling forms, triggering searches, submitting data, or interacting with any active application. The effect is execution of UI actions, not just reading or writing data in a structured way.

Documented attack patterns abuse exactly the kind of access browser_type gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Apple Shortcuts, and nothing reaches the server without passing your rules. This is the rule we recommend for browser_type:
{
"version": "1",
"default": "deny",
"tools": {
"browser_type": {
"limits": [
{
"counter": "browser_type_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}browser_type 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.

Type text character by character (simulates real keystrokes). Useful for search boxes and autocompletes that respond to individual key events. It is categorised as a Execute tool in the Apple Shortcuts MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Apple Shortcuts MCP server in PolicyLayer and add a rule for browser_type: 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 Apple Shortcuts. Nothing to install.
browser_type 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 browser_type 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 browser_type. 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.
browser_type is provided by the Apple Shortcuts MCP server (@mindstone/mcp-server-apple-shortcuts). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Apple Shortcuts, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
