api record

Hosted 2s.io MCP — pay-per-call data + watchers, settled in USDC on Base via x402. Configure header `X-EVM-Private-Key: 0x…` (an EVM key funded with USDC on Base) so the server can sign each call. ⚠️ Your key transits 2s infrastructure here; for keys that never leave your machine, use the SDK / `npx @2sio/mcp` instead. watchers.* arm a signed push callback so you never poll.

_ is it live, free and safe measured by this hub
Is 2s.io live?
No — it has stopped answering the hub's checks (checked 2h ago). It answered 85% of checks over the last 30 days.
Is 2s.io 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 2s.io have?
1 tool: Discover 2s endpoints.
Is 2s.io 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.

_ usage and payments 30 days

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

what callers paid

_ what it can do 1 tools
1 auth-required 1 of 1 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.

  • discover-endpoints auth-required never probed

    Given a natural-language description of a task, returns the best-matching 2s API endpoints — each with its id, HTTP path, method, group, description, and per-call USD price — so you can call the one that answers your question. Deterministic keyword + synonym ranking over the live 2s catalog (no LLM, zero upstream). The routing result is free; the endpoints it returns are pay-per-call via x402.

_ 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 86b052a7f311c2a8.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/86b052a7f311c2a8/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
100%

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.
