type_text · InSite MCP: Risk & Policy

WHAT IT DOES

What type_text does on InSite

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

WHY IT NEEDS A POLICY

Why type_text needs a policy

The tool programmatically enters text into input fields, which constitutes reversible modification of form state and data. While the operation itself is non-destructive and does not execute arbitrary code, it can be misused to inject malicious input, pollute databases, perform form spam, or submit unwanted form data.

From the tool's definition Tool name 'type_text' and description 'Type text into an input element' indicates creation/modification of form data and page state. This is a write operation that modifies content in interactive elements.

Verdict

type_text Rate-limited

type_text 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.
