Is motionspec-mcp-server live?

Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.

Is motionspec-mcp-server free to use?

Yes — the hub reached it with no key and no payment.

What tools does motionspec-mcp-server have?

5 tools: motion_validate, motion_stats, motion_audit, motion_compile, motion_catalog.

Is motionspec-mcp-server safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• motion_catalog reads open 13h ago

  Returns the catalog of verified motion primitives (names, purpose, parameter schemas, defaults) plus the authoring rules for writing a MotionSpec. Call this FIRST, then write the spec yourself and validate it with motion_validate (motion_compile runs in the CLI or with a key on the hosted endpoint). Free motion check: motionspec.dev/motion-check · keys for the hosted endpoint: motionspec.dev/pricing?src=mcp.

• motion_validate reads unknown 6h ago

  Checks a MotionSpec against the schema, the primitive allow-list, parameter bounds and injection rules. Fail-closed: returns ok=false with precise errors. Returns {ok, errors, warnings, deprecations, catalogVersion}. IMPORTANT: warnings[] carries the WCAG 2.2.2 / reduced-motion findings and can be non-empty while ok=true — a spec that compiles is not automatically accessible. Use to pre-check a spec before compiling.

• motion_stats reads unknown 6h ago

  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 structuredContent {ok:false, error:'PAYWALL', tool, upgrade} and text guidance. To use motion_stats on the hosted endpoint, connect with an x-motionspec-key header. Read local telemetry for free with 'npx -p motionspec motion stats' (MIT). This reads this machine's local activity, not hosted usage.

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

0 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.
