5 Nov a tool description was rewritten2 times that day get_swap_status

and 1 more, back to 5 November 2026

Nothing serious here today

Today is the operative word: we check Sablebolt swaps every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 8

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

swap

create_swap

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.

get_swap_status

Status of one swap by id: stage (1 waiting … 5 done), deposit and payout addresses, amounts (receiveAmount is the estimate after the network fee; amountReceived the deposit as credited once seen — when it differs from amountFrom the estimate no longer applies; amountTo the actual payout once known), both transaction hashes.

swap_page_link

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.

assets

list_assets

Every asset the swap form knows, with slug, ticker, network, confirmations, extra-id name and whether it is available right now.

limits

get_limits

Minimum and maximum amount for a route, in the asset you send.

quote

get_quote

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.

routes

list_routes

Every route with its own page (from/to slugs) and whether both sides are available right now.

validate

validate_address

Whether an address has the right format for an asset. Does not check who owns it or whether an exchange needs a memo.

Is Sablebolt swaps working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 398 ms. The bar chart above shows every period we have measured.

How do I connect Sablebolt swaps?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Sablebolt swaps need an API key?

No. Sablebolt swaps completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Sablebolt swaps?

It answers our handshake in 398 ms on average, which is faster than 33% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
