Mcp Ezpath
Let your coding agent fetch the best Base-chain swap quote by racing 0x, ParaSwap, Aerodrome, and Uniswap V3 before you wire trades into a DeFi or agent product.
Overview
mcp-ezpath is a MCP server for the Build phase that races four Base DEX aggregators and returns the best swap quote with X402 micropayment per request.
What is this MCP server?
- Meta-router races 0x, ParaSwap, Aerodrome, and Uniswap V3 for the best quote on Base
- X402 pay-per-use billing with auto-signed EIP-3009 TransferWithAuthorization from your wallet
- Fixed 0.03 USDC per quote request via EZPATH_WALLET_KEY
- npm package mcp-ezpath v0.1.1 with stdio transport
- 4 DEX sources raced: 0x, ParaSwap, Aerodrome, Uniswap V3
- Server version 0.1.1
What problem does it solve?
Solo builders wiring agents into Base swaps waste time comparing 0x, ParaSwap, Aerodrome, and Uniswap V3 manually and lack a single MCP call for best-quote routing.
Who is it for?
Indie builders shipping Base-native agents or APIs that need programmatic best-quote DEX comparison with a funded USDC wallet.
Skip if: Non-crypto products, teams that cannot hold a hot wallet key in the agent environment, or builders who need mainnet chains beyond Base without their own routing layer.
What do I get? / Deliverables
Your agent can request one MCP quote that picks the winning route among four sources while paying 0.03 USDC per call from your configured Base wallet.
- Best-quote swap path across four Base DEX sources
- Signed micropayment authorization per quote request
- Agent-callable swap research without manual DEX UI checks

How it compares
On-chain DEX quote MCP integration, not a brainstorming or code-review agent skill.
