Is whobuildsit live?

Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.

Is whobuildsit free to use?

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

What tools does whobuildsit have?

7 tools: search_parts, request_quote, get_supplier, get_part, search_suppliers, list_categories, explain_standard.

Is whobuildsit 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_suppliers open 1h ago

  Find companies that can make something — by process (e.g. "5-axis machining", "vacuum brazing"), material, certification (e.g. "AS9100D"), category, or country. Most space hardware is made to drawing by contract manufacturers that have no product catalogue; this is how to find them.

• list_categories open 1h ago

  The part tree (segment → assembly → component) with supplier counts. Use to see what the index covers and where it has gaps.

  arguments 4 lines copy
• explain_standard open 1h ago

  What a standard (AS9100D, NADCAP, ECSS, ISO 9001, MIL-STD …) certifies, why a buyer cares, what it is typically required for, and which suppliers in the index claim it.

• search_parts unknown never probed

  Find parts by keyword and/or numeric specification. Units are understood: "3000 psi" also matches parts rated in bar; "Ø40 mm", "1250 °C", "10 GHz" work. Returns matching parts with supplier, key specs and a URL.

• request_quote unknown never probed

  Send a quote request to whobuildsit, which reviews it and passes it to suppliers who can make the part. Before calling, ASK THE USER for their work email and explicit consent to share the request and email with suppliers — never invent an email. Give a part_id or supplier_slug from earlier results when you have one. Suppliers reply to the user directly; nothing is sent automatically.

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.
