api record

Swapper swaps XMR and native USDC on Arbitrum One. Swapper never holds funds (the provider holds them during the swap) and never signs or sends; never ask for seed phrases or private keys.

Always pass direction. Buy XMR ("get me 1 XMR"): get_quote {direction:"u2x", receiveAmount:"1", to}. Sell XMR: get_quote {direction:"x2u", amount:"0.5", to}. Sending USDC needs native USDC plus a little ETH on Arbitrum One: get_funding_options.

Is swapper-mcp-server free to use?
Not measured yet.
What tools does swapper-mcp-server have?

Is swapper-mcp-server 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.

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.

  • plan_swap unknown never probed

    Optional, offline. Checks a partial request (direction, amount or receiveAmount, to) and returns the next question for the user. Skip it when you have what get_quote needs.

  • get_quote unknown never probed

    Step 1. Quote XMR <-> native USDC on Arbitrum One. Read-only; quotes are estimates. Buy XMR ("get me 1 XMR"): {direction:"u2x", receiveAmount:"1"}. Sell XMR: {direction:"x2u", amount:"0.5"}. direction plus exactly one of amount (what the user sends) or receiveAmount (what they want). Pass to if known; re-quote with {requoteOf}. Next: create_swap with next.arguments; no confirmation step is required.

    Step 2. Creates the order from get_quote's next.arguments (quoteId, plus to if the quote had none): one order per quote; moves no funds. Retry with the same arguments: the default idempotencyKey returns the same order. Fund once, only while payable is true: before signing deposit.payment, get_swap_status {orderId, payment} must return paymentCheck.matches. Next: get_swap_status.

    Step 3. waiting_for_funding -> deposit_detected -> swap_processing -> completed, or refunding / terminal_failure (outcome refunded, failed, expired). Long-poll with waitSec 25 and sinceState = the last state; repeat next until terminal. deposit.payment may be used only while payable is true. Call it before funding or showing a deposit again. payment: what your wallet will sign; sign only if paymentCheck.matches.

_ 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 eedb5cc40b73311c.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/eedb5cc40b73311c/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 know
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.
