What counts as breaking

Tool removed
Argument newly required
Argument removed
Incompatible JSON Schema type/format changes
Enum value removed
Narrowed numeric/string bounds
Behavioral annotation changes (readOnlyHint, destructiveHint, etc.) as warnings

Description-only edits are ignored.

Safe defaults

Only explicitly supplied HTTPS catalogs are fetched
No credentials in v1
Failed downloads do not overwrite baselines
Default/demo input must stay fast and public

Baseline modes

Mode	Behavior
`auto`	Create the first baseline for a `monitorId`, then compare later without overwriting
`compareOnly`	Compare only; error if no baseline exists
`accept`	Write reports, then replace the stored baseline

Pricing

Pay per event: MCP tool comparison completed after successful report artifacts are written. Failed fetches/invalid catalogs are not charged for the comparison event.

Authorization

Only analyze tool catalogs you own or are authorized to access.
