AI agents use type to create or update resources in Yandex Browser MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Yandex Browser MCP Server environment.
The tool inputs text into browser fields, which constitutes data modification. This is reversible (text can be cleared or changed), placing it in the Write category rather than Execute or Destructive. Severity is medium because misuse could result in unintended form submissions, data entry into wrong fields, or manipulation of web application state, but without inherent destructive capability.
From the tool's definition Tool description indicates 'Ввести текст в поле в указанной вкладке' (enter text in a field in the specified tab), which modifies form fields.
Documented attack patterns abuse exactly the kind of access type gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Yandex Browser MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for type:
{
"version": "1",
"default": "deny",
"tools": {
"type": {
"limits": [
{
"counter": "type_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}type 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.

Ввести текст в поле в указанной вкладке. It is categorised as a Write tool in the Yandex Browser MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Yandex Browser 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 Yandex Browser MCP Server. Nothing to install.
type is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
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.
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.
type is provided by the Yandex Browser MCP Server MCP server (t1trit/yandex-browser-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Yandex Browser MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
