adexto-x402
Registry code: 6a199bbe2fae459d
ADEXTO sells positions in bonding-curve markets across chains, paid for with USDC on Base over x402. Call list_markets to see what exists, quote_buy to price one without paying, then buy_token with a signed payment. You never need gas on the destination chain and never need to bridge. Every tool except buy_token is free, and buy_token's first response is a 402 challenge, which is expected rather than a failure. A ticker can trade on more than one chain: pass chainId from list_markets to pick one. Every market can be staked, in its own stake contract or its chain's stake hub, and a stake opens…

what callers paid
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.
launch_market unknown never probed
A multi-turn task. Send a data part {skill:'launch_market', chainId, name, symbol, deployer, agentId?, description?}. The task returns TASK_STATE_INPUT_REQUIRED with attestationMessage: sign it with personal_sign (EIP-191) from deployer and reply on the same task with {attestationSignature}. The message ends with an acceptance of the ADEXTO Terms and Acceptable Use Policy (adexto.xyz/terms), so signing it is the deployer's acceptance. The task then returns the unsigned launch transaction as an artifact: send it from deployer (value 0, gas only) and reply with {txHash}. When it is mined the market is listed and the task completes with the market artifact.
get_market reads unknown never probed
One market by ticker, optionally on one chain. Data part {skill:'get_market', symbol, chainId?}.
list_markets reads unknown never probed
Every listed ADEXTO market: symbol, chain, token, curve, price in the native asset and page URL. Data part {skill:'list_markets'}.
buy_token moves money unknown never probed
A two-turn task on the a2a-x402 v0.2 extension. Send a data part {skill:'buy_token', symbol, chainId, to}. The task returns TASK_STATE_INPUT_REQUIRED with metadata x402.payment.status 'payment-required' and x402.payment.required {x402Version, accepts}. Sign the EIP-3009 transferWithAuthorization in accepts[0] (USDC on Base, exact amount, to payTo) with your own wallet and reply on the same task with metadata {x402.payment.status:'payment-submitted', x402.payment.payload:{x402Version, scheme, network, payload:{signature, authorization}}}. The curve on the market's chain sends the tokens to `to` first, then the USDC settles on Base; the task completes with x402.payment.receipts. You never need gas on the market's chain, and this server never signs anything.
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 id6a199bbe2fae459d.

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.
