Sablebolt: account-free crypto swaps between two addresses (https://sablebolt.io). Every tool is read-only except create_swap, which creates a swap and returns a payment instruction for a wallet you control. A swap for a person is completed by that person on the page: open the link, check the amount, both addresses and the memo on screen, then send the deposit from your own wallet. An agent that controls the sending wallet itself uses create_swap and pays the instruction it gets back.

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
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.
list_routes open 1h ago
Every route with its own page (from/to slugs) and whether both sides are available right now.
{ "type": "object", "properties": {} }arguments 4 linesget_quote unknown 1h ago
Floating estimate for a route and amount: amountTo, networkFee (taken out of the payout), receiveAmount, rate. The final amount is set when the deposit confirms.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "from", "to", "amount" ], "properties": { "to": { "type": "string" }, "from": { "type": "string" }, "amount": { "type": "string", "description": "decimal amount you send, as a string" } } }arguments 21 lineslist_assets unknown never probed
Every asset the swap form knows, with slug, ticker, network, confirmations, extra-id name and whether it is available right now.
{ "type": "object", "properties": {} }arguments 4 linesvalidate_address unknown never probed
Whether an address has the right format for an asset. Does not check who owns it or whether an exchange needs a memo.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "asset", "address" ], "properties": { "asset": { "type": "string", "description": "asset slug" }, "address": { "type": "string" } } }arguments 17 linesget_swap_status unknown never probed
Status of one swap by id: stage (1 waiting … 5 done), deposit and payout addresses, amounts, both transaction hashes.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "id" ], "properties": { "id": { "type": "string", "description": "swap id from the status page URL" } } }arguments 13 linescreate_swap unknown never probed
Creates the swap and returns the payment instruction: the one-time deposit address, the memo if the chain needs one, the exact amount in decimal and in base units with the decimals and token contract as listed by the liquidity partner, a wallet URI where a standard exists (BIP-21, ERC-681, Solana Pay, Monero, TON), and the status URL. Use it only when you control the wallet at fromAddress and will send the deposit yourself; for a person use swap_page_link. The deposit must come from fromAddress; there is no refund address — a swap that cannot be completed is handled by support from the swap id. Floating rate: the final amount is set when the deposit confirms.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "from", "to", "amount", "fromAddress", "toAddress" ], "properties": { "to": { "type": "string", "description": "asset slug to receive, e.g. btc" }, "from": { "type": "string", "description": "asset slug you send, e.g. usdt-trc20" }, "amount": { "type": "string", "description": "decimal amount you send, as a string, within get_limits" }, "extraId": { "type": "string", "description": "memo / destination tag / payment ID for the receiving side, only where that asset needs one" }, "toAddress": { "type": "string", "description": "the receiving address for the `to` asset" }, "fromAddress": { "type": "string", "description": "the address you will send the deposit from (a wallet you control)" }, "fromExtraId": { "type": "string", "description": "the sending side's extra id, only if your wallet attaches one" } } }arguments 41 linesswap_page_link unknown never probed
The page where the person completes the swap, with the amount prefilled. A swap for a person is completed by that person on the page: open the link, check the amount, both addresses and the memo on screen, then send the deposit from your own wallet. An agent that controls the sending wallet itself uses create_swap and pays the instruction it gets back.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "from", "to" ], "properties": { "to": { "type": "string" }, "from": { "type": "string" }, "amount": { "type": "string" } } }arguments 19 linesget_limits unknown 1h ago
Minimum and maximum amount for a route, in the asset you send.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "from", "to" ], "properties": { "to": { "type": "string", "description": "asset slug you receive, e.g. btc" }, "from": { "type": "string", "description": "asset slug you send, e.g. usdt-trc20" } } }arguments 18 lines
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 idb5266900131991e1.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/b5266900131991e1/claim.

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.
