Available tools 16

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

cow
cow_build_order
Build an unsigned CoW market order as EIP-712 typed data (eth_signTypedData_v4) plus the one-time vault-relayer approval tx if needed. No gas for the swap itself.
cow_order_status
Status of a CoW order by uid.
cow_post_order
Submit a signed CoW order (from cow_build_order) to the CoW Protocol order book; returns orderUid + explorer link.
cow_quote
Gasless CoW Protocol market-order quote (ethereum, base, arbitrum, polygon, bsc; ERC-20 sell tokens). MEV-protected batch auction. Includes the same disclosed 0.1% fee as a CoW partner fee.
debridge
debridge_build_tx
Build an unsigned deBridge DLN cross-chain order transaction (plus ERC-20 approval tx if needed) for sender to sign on the source chain. Same fees as debridge_quote. Returns orderId for tracking.
debridge_order_status
Status of a deBridge DLN order by orderId.
debridge_quote
Cross-chain EVM swap quote via deBridge DLN (ethereum, base, arbitrum, optimism, polygon, bsc; e.g. USDC on Base -> ETH on Arbitrum). Includes the same disclosed 0.1% Quietwork affiliate fee PLUS deBridge's own fees (4 bps protocol fee, flat native-coin fee, ~4 bps solver margin, solver gas), all itemised.
crosschain
crosschain_create_shift
Create a variable-rate SideShift order; returns a deposit address. Funds settle directly to settleAddress (non-custodial for us).
crosschain_rate
Cross-chain / cross-asset rate (BTC, XMR, LTC, SOL, ETH, USDC on many networks) via SideShift.ai. Same rate as sideshift.ai.
swap
swap_build_tx
Build an unsigned, non-custodial swap transaction (plus ERC-20 approval tx if needed) for the caller's wallet to sign. Same fee as swap_quote.
swap_quote
Best-price same-chain token swap quote via the KyberSwap aggregator (ethereum, base, arbitrum, optimism, polygon, bsc). Includes a disclosed 0.1% integrator fee.
velora
velora_build_tx
Build an unsigned Velora Augustus v6.2 swap tx plus ERC-20 approval tx if needed. Same fee as velora_quote.
velora_quote
Same-chain swap quote via Velora (ParaSwap) Market (ethereum, base, arbitrum, optimism, polygon, bsc) with the same disclosed 0.1% Quietwork partner fee (Velora keeps 15% of it; no other Velora fee). Often a better price than KyberSwap on some pairs; compare with swap_quote.
zerox
zerox_build_tx
Build an unsigned 0x Swap API (AllowanceHolder) transaction plus ERC-20 approval tx if needed; output goes to sender. Same fees as zerox_quote (0.1% ours + 0x's ~0.15% zeroExFee).
zerox_quote
Same-chain swap quote via the 0x Swap API (ethereum, base, arbitrum, optimism, polygon, bsc) with the same disclosed 0.1% Quietwork integrator fee PLUS 0x's own ~0.15% platform fee (Standard plan; returned as zeroExFee), so total fees are higher than on KyberSwap.
shift
shift_status
Status of a SideShift order created here.

Quietwork Swap — questions

Answers built from our own checks of this server.

What can Quietwork Swap do?
It exposes 16 tools, read directly from the server on our last check. Among them: cow_build_order, cow_order_status, cow_post_order, cow_quote, crosschain_create_shift, crosschain_rate and 10 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
What is Quietwork Swap mostly used for?
Its tools cluster around cow, debridge and crosschain. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Quietwork Swap working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 126 ms. The bar chart above shows every period we have measured.
How do I connect Quietwork Swap?
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 Quietwork Swap need an API key?
No. Quietwork Swap completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 16 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Quietwork Swap?
It answers our handshake in 126 ms on average, which is faster than 90% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
