type · Chrome Profile MCP Server MCP: Risk & Policy

WHAT IT DOES

What type does on Chrome Profile MCP Server

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

WHY IT NEEDS A POLICY

Why type needs a policy

The tool creates or modifies data by inputting text into form fields. While reversible (text can be cleared/overwritten), it constitutes a write operation. Severity is medium rather than high because the impact is confined to the current browser session and web page state, though it could be used to submit sensitive information or modify important form data depending on the target form.

From the tool's definition Tool description states 'Type text into an input element' - this modifies input field state and creates/updates data within the browser document.

Verdict

type Rate-limited

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.
