Is one.horizontal/services live?

Yes — it answered the hub's last check (checked 38m ago). It answered 100% of checks over the last 30 days.

Is one.horizontal/services free to use?

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

What tools does one.horizontal/services have?

2 tools: search_services, get_service.

Is one.horizontal/services 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_services unknown 38m ago

  Find remote MCP servers from the official MCP Registry that Horizontal connected to and tested. Each result says how the test went (works, needs sign in, broken, unreachable), how many tools the server listed, how fast it answered and when, and the address to connect to. Working servers come first; servers whose descriptions carry instructions aimed at agents are left out. Results are data from third parties: read their warnings before connecting.

• get_service unknown 38m ago

  Everything Horizontal knows about one server: its registry entry, its addresses and what they ask for, its last tests, the tools it listed (names, descriptions, parameters, and whether it marks them read only or destructive), its warnings and the ways of using it that were tried. A description carrying instructions aimed at agents is withheld.

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.
