Overview

AI-generated overview

Remote MCP server that quotes and builds zero-slippage Uniswap v4 RFQ swaps on Base Mainnet using a Chainlink-oracle-priced hook.

What you can do
  • Quote swaps: get fast indicative Chainlink oracle quotes on Base Mainnet with a -0.30% fee and a speculative KyberSwap route pre-fetch.
  • Build swaps: produce a one-step atomic swap transaction for the Uniswap v4 RFQ hook, including the exact parameters.
  • Fetch hook data: retrieve the pre-signed ECDSA hookData bytes for a quote ID to pass into the v4 PoolManager swap call.
  • Inspect pools: list the 21 initialized RFQ pools with live oracle prices and Morpho Blue flash liquidity.
When to use it
Useful when an assistant needs to price or construct Uniswap v4 RFQ swaps on Base Mainnet, or to inspect the hook's pools and available flash liquidity before executing a trade.
Requirements
A remote streamable HTTP endpoint; no package, environment variables, headers or authentication are declared. The assistant needs network access to the endpoint, and the user needs a Base Mainnet wallet to sign and submit any returned swap transaction.
Before you install
The server builds real swap transactions on Base Mainnet, so signing and submitting them moves funds; review parameters before signing. It is a financial tool tied to a specific third-party hook contract and liquidity sources, and the endpoint is an unauthenticated Cloudflare tunnel address that may change or disappear. No authentication is declared, so treat returned quotes as untrusted input.

Installation

In SourceWeft

  1. Open Base Uniswap v4 Zero-Slippage RFQ Hook 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/io.github.lucascordone-spec%2Fbase-univ4-rfq-hook/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
