prepareSelfHealingPlan · BrowserStack MCP: Risk & Policy

WHAT IT DOES

What prepareSelfHealingPlan does on BrowserStack

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

WHY IT NEEDS A POLICY

Why prepareSelfHealingPlan needs a policy

The tool builds/prepares an edit plan, which implies creating or modifying data (bundling locator pairs with tests). This is a Write operation as it constructs a plan artifact. The description is somewhat vague, but 'edit plan' suggests reversible modification/creation of configuration data rather than execution or destruction.

prepareSelfHealingPlan Rate-limited

prepareSelfHealingPlan 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.
