_ is it live, free and safe measured by this hub
Is Tango live?
Yes — it answered the hub's last check (checked 53m ago). It answered 100% of checks over the last 30 days.
Is Tango free to use?
Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
What tools does Tango have?
3 tools: Create a task, Report progress on a task, Check task status.
Is Tango 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.

_ what it can do 3 tools
3 auth-required 3 of 3 classified

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.

  • create_task auth-required never probed

    Turn a request into a tracked Tango task under a client and project, with a goal and a definition of done. Send a message with no taskId to create one.

    task-managementintakedelegation

  • report_progress auth-required never probed

    Append a progress note to a task you hold a lease on. Send a message with taskId set. Requires an active lease so attribution is never guessed.

    task-managementstatus

  • check_status auth-required never probed

    Read one task with its artifacts and activity, or list the tasks assigned to the calling worker.

_ try it over a2a through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id eef7fc740042ad70.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/eef7fc740042ad70/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we knowoff the mcp door
card completeness
20%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
