  Requires a Dev Key ($39/mo) or Agency plan ($249/mo) on the hosted endpoint (motionspec.dev/pricing?src=mcp). This unauthenticated call returns access information only; it does not compile code, fetch URLs, run an audit or read usage data. Arguments are optional and unused. Returns isError:true with
• motion_catalog ~159 tokens
  Returns the catalog of verified motion primitives (names, purpose, parameter schemas, defaults) plus the authoring rules for writing a MotionSpec.

Returns {ok, errors, warnings, deprecations, catalogVersion}. IMPORTANT: warnings[] carries the WCAG 2.2.2 / reduced-motion findings and can be n
