WHAT IT DOES

What type does on Chrome MCP Server

AI agents invoke type to trigger actions in Chrome MCP Server. 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.

THE RISK

High Risk

Why type needs a policy

This tool triggers browser actions (typing and key presses) in a live Chrome browser session. It can submit forms, trigger JavaScript events, and interact with web applications in ways that have real-world side effects depending on what is typed and where.

From the tool's definition 'Type text into the currently focused element, with support for special keys like {Enter}, {Tab}, etc. Use {Enter} for newlines in textareas or to submit forms.'

Documented attack patterns abuse exactly the kind of access type gives an agent:

POLICY

How to control type

PolicyLayer is an MCP gateway — it sits between your AI agents and Chrome MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for type:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "type": {
      "limits": [
        {
          "counter": "type_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

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.

Create a free account and register Chrome MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about type

What does the type tool do? +

Type text into the currently focused element, with support for special keys like {Enter}, {Tab}, etc. Use {Enter} for newlines in textareas or to submit forms. NEVER USE \n\n IN THE TEXT YOU TYPE. Use {Ctrl+A} to select all text in the focused element. If you think you. It is categorised as a Execute tool in the Chrome MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on type? +

Register the Chrome MCP Server MCP server in PolicyLayer and add a rule for 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 Chrome MCP Server. Nothing to install.

What risk level is type? +

type is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit type? +

Yes. Add a rate_limit block to the 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.

How do I block type completely? +

Set action: deny in the PolicyLayer policy for 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.

What MCP server provides type? +

type is provided by the Chrome MCP Server MCP server (lxe/chrome-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
