Is space-mushroom live?

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

Is space-mushroom free to use?

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

What tools does space-mushroom have?

11 tools: compare, get_term, search_materials, list_claims, prove_claim, what_is_missing, resolve_designation, search_sources, ….

Is space-mushroom 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.

• list_properties open 1h ago

  The property names in use, with their canonical unit and whether higher or lower is better. Use these names with get_material and compare.

• compare unknown never probed

  Line several materials up on one property, with each value, its conditions and its source. Values are also given in the property's canonical unit (value_canonical), so they can be ranked directly. Values measured under different conditions are listed separately and are not averaged.

  For one material and a list of properties: which have sourced data (and the strongest evidence) and which have none. "no_data" means not covered yet, not known to be safe.

• resolve_designation unknown never probed

  Which material a code names: a UNS number, EN number or name, DIN, JIS, AISI or SAE number, ASTM or AMS specification, or trade name (for example S31600, 1.4401, SUS316, A240). Case, spaces and hyphens do not matter, and a short code also lists the codes that start with it. Each row gives the system, the code, a note (product form or a caveat) and whether the match is exact. A specification such as ASTM A240 covers many grades and returns every material that cites it. A note of "nearest equivalent" means the source itself hedges: do not treat the two as the same grade.

• find_materials unknown 1h ago

  Requirements in, candidates out. Each material gets a verdict: pass (every constraint met by a sourced value), fail, or unknown (no data on a constraint, so it cannot be ruled in or out). Every constraint reports pass, fail or no_data and the strongest evidence level behind it (flown, measured, derived, inferred, estimated, predicted). By default only passes and unknowns are returned, passes first. Context narrows which values count: at_temperature (degrees C; values measured at another temperature do not count), flown_only (only values measured in the real space environment), environment, include_failed, limit. Materials with no data on any constraint are not listed: use what_is_missing to see coverage for one material.
