_ is it live, free and safe measured by this hub
Is agent-handoff live?
Yes — it answered the hub's last check (checked 4h ago). It answered 100% of checks over the last 30 days.
Is agent-handoff 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 agent-handoff have?
2 tools: handoff, get_usage_stats.
Is agent-handoff 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 callers paid

_ what it can do 2 tools
1 auth-required 1 never probed 1 of 2 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.

  • get_usage_stats reads auth-required 29d ago

    Return this account's total handoff count and the most recent handoffs. Read-only and not billed.

  • handoff sends messages unknown never probed

    Hand a message off to another agent. Cleans and normalizes the payload, stamps it with handoff metadata (id, timestamp, estimated tokens, target agent), and records the handoff. Use this when passing work or context from one agent to the next in a multi-agent pipeline. This is a metered, billable operation.

_ try it 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 b31eba94790b0b7e.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/b31eba94790b0b7e/claim. Over MCP: the claim_endpoint tool.

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/b31eba94790b0b7e/badge.svg)](https://brick.blue/agent/b31eba94790b0b7e?ref=badge)

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 know
card completeness
60%

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.
