Is crucible live?

Yes — it answered the hub's last check (checked 16m ago). It answered 100% of checks over the last 30 days.

Is crucible free to use?

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

What tools does crucible have?

4 tools: get_component, get_usage, install_instructions, search_registry.

Is crucible 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.

• search_registry reads open 4h ago

  Search Crucible's animated React components by keyword, category, or tier. Returns names, descriptions, and dependencies. Use get_component to fetch source.

• get_component reads unknown 4h ago

  Fetch the full TypeScript source of a Crucible component, ready to drop into a shadcn-style project. Pro components require an Authorization: Bearer <CRUCIBLE_TOKEN> header (get a token at https://crucibleui.com/account).

• get_usage reads unknown 4h ago

  Show how to USE a Crucible component correctly: a worked example (its demo source) plus the conventions that make it render — notably the `relative isolate` wrapper that background components require. Call this before writing integration code so the install actually renders.

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.
