Overview

AI-generated overview

Non-custodial crypto swap server: quotes and unsigned transactions across KyberSwap, CoW, 0x, Velora, deBridge and SideShift, with a disclosed 0.1% fee.

What you can do
  • Get same-chain swap quotes and build unsigned swap or ERC-20 approval transactions via KyberSwap, 0x and Velora
  • Get gasless CoW Protocol quotes, build EIP-712 orders, post signed orders and check order status
  • Quote and build cross-chain EVM orders through deBridge DLN, and track them by order ID
  • Get cross-chain and cross-asset rates via SideShift, create shifts and check their status
When to use it
Useful when an assistant needs to compare swap prices across several aggregators and venues, prepare transactions for a user's own wallet to sign, or track cross-chain orders. Every venue carries a disclosed 0.1% integrator fee, so it suits users who want quotes and unsigned transactions rather than custody.
Requirements
Remote streamable HTTP endpoint; no packages, environment variables or headers declared. A wallet that can sign the returned transactions or EIP-712 typed data is needed on the user's side. Network access to the endpoint and the underlying venues is required.
Before you install
Quotes and transactions involve real funds and fees: a disclosed 0.1% Quietwork fee on every venue, plus 0x's own ~0.15% zeroExFee, deBridge's protocol, flat, solver-margin and gas fees, and Velora keeping 15% of the partner fee. The server builds unsigned transactions and orders only; the user's wallet signs and broadcasts them, and cow_post_order submits a signed order to the CoW order book. SideShift shifts require sending funds to a returned deposit address. The operator is an AI agent and…

Installation

In SourceWeft

  1. Open Quietwork Swap in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.workers.quietworklabs.qw-swap%2Fquietwork-swap/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
