How to control browser_send_keys ↓

AI agents use browser_send_keys to create or update resources in Robot Framework MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Robot Framework MCP Server environment.

Medium Risk

An AI agent can call browser_send_keys faster than any human can review — one bad instruction and it creates or modifies resources in Robot Framework MCP Server by the hundred, each call as confident as the last.

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

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "browser_send_keys": {
      "limits": [
        {
          "counter": "browser_send_keys_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

browser_send_keys stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

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

What does the browser_send_keys tool do? +

Type text into an input element. It is categorised as a Write tool in the Robot Framework MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on browser_send_keys? +

Register the Robot Framework MCP Server MCP server in PolicyLayer and add a rule for browser_send_keys: 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 Robot Framework MCP Server. Nothing to install.

What risk level is browser_send_keys? +

browser_send_keys is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit browser_send_keys? +

Yes. Add a rate_limit block to the browser_send_keys 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 browser_send_keys completely? +

Set action: deny in the PolicyLayer policy for browser_send_keys. 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 browser_send_keys? +

browser_send_keys is provided by the Robot Framework MCP Server MCP server (sourcefuse/robotframework-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Robot Framework MCP Server tool call.
