How do I use mev-history-mcp?

1. Click on "Deploy Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@mev-history-mcp check my wallet for MEV exposure on Base" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

mev-history-mcp

x402 MCP for EVM MEV history. Pay-per-call USDC on Base. No signup, no API key, no Etherscan key.

Live: https://mev-history-mcp.mtree.workers.dev

Endpoints

Path	Price	What it does
`POST /v1/wallet/mev_exposure`	$0.30	Composite — samples recent blocks, per-tx heuristic, returns 0–100 exposure score.
`POST /v1/tx/sandwich_check`	$0.05	Was this tx sandwiched? Confidence (none/weak/medium/strong/confirmed) + attacker addr.
`POST /v1/pool/recent_mev_density`	$0.10	Pool's recent sandwich density (0.0–1.0) + sample sandwiches.

Methodology

Flag tx N as sandwiched iff:

tx N-1 and N+1 share a from-address that differs from tx N, AND
all three target a known DEX router on the same chain.

Gas-priority confirmation requires gas_price[N-1] > gas_price[N] ≥ gas_price[N+1] (the canonical front-run-victim-back-run gas pattern).

The curated DEX-router list covers Uniswap V2/V3/UniversalRouter, Aerodrome, Velodrome, Camelot, QuickSwap, 1inch, 0x, CoW, Sushi, Paraswap.

Chains

ethereum / base / arbitrum / optimism / polygon. Default base. Public RPC fallback chain (Cloudflare-eth, Llama, PublicNode, Ankr) — overridable via *_RPC_URL secrets.
