- Is xsignal live?
- Yes — it answered the hub's last check (checked 23h ago). It answered 100% of checks over the last 30 days.
- Is xsignal free to use?
- No — it charges per call, quoted in its own 402 answers.
- What tools does xsignal have?
- 5 tools: Base token market intel, Base token preflight (safety + momentum), Outcome-priced momentum intent (abstains), Real-time X/social signal, Fused token brief (meal).
- Is xsignal 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
Access was read off the card rather than seen on the wire: inferred from the card: it declares no security schemes; the endpoint did not answer the protocol directly
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.
token-market-intel unknown never probed
Liquidity/volume/price/age/buy-sell flow + mechanical flags for a Base token (market data, NOT a trust rating). Best as an input to the brief. x402-paid at /token ($0.01; 3 free per wallet via ?wallet=0x…).
base-preflight unknown never probed
One call fuses MainStreet on-chain SAFETY (SAFE/WATCH/AVOID + rug flags) with xsignal MOMENTUM into a single recommendation (GO / CAUTION / AVOID / NEUTRAL) - is this token safe to touch AND moving? Safety gates momentum. x402-paid at /preflight ($0.05; 3 free per wallet via ?wallet=0x…). Not financial advice.
intent-momentum unknown never probed
The only x402 signal that ABSTAINS below your confidence bar. Post {addr, min_confidence} → pay a flat fee, then a mechanical momentum verdict (gaining/fading) if confidence clears your bar, else a calibrated abstain. Paid answers carry a keyless tamper-evidence receipt. x402-paid at /intent (from $0.01; 3 free per wallet via ?wallet=0x…).
real-time-signal unknown never probed
Fresh, scored (virality+freshness), cited social signal for a topic. x402-paid at /signal (from $0.01 USDC on Base; 3 free per wallet via ?wallet=0x…).
token-brief unknown never probed
One call fuses Base token market intel + real-time social signal into a "what is happening with $TOKEN now" brief (market flags + cited top posts + a non-advisory summary). x402-paid at /brief ($0.05; 3 free per wallet via ?wallet=0x…).
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.
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.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - 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. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idba02dbe94ea1045f.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/ba02dbe94ea1045f/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.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
