Is com.mcjars/catalog live?

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

Is com.mcjars/catalog free to use?

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

What tools does com.mcjars/catalog have?

3 tools: get_download, list_versions, list_providers.

Is com.mcjars/catalog 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_providers open 1h ago

  List available Minecraft server software and proxy providers with their slugs, descriptions, and latest-version summaries.

• get_download unknown 1h ago

  Get an exact provider build or the newest matching build when version is omitted. Minecraft and loader versions are separate: use minecraftVersion for the game, version for the full provider build. Returns URLs only; does not download or execute files. No match returns an error without substituting another game version or channel.

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.
