In the chat, type
@followed by the MCP server name and your instructions, e.g., "@mev-history-mcpcheck if tx 0xabc123 was sandwiched on base"
That's it! The server will respond to your query, and you can continue using it as needed.

Endpoints
Path | Price | What it does |
| $0.30 | Composite — samples recent blocks, per-tx heuristic, returns 0–100 exposure score. |
| $0.05 | Was this tx sandwiched? Confidence (none/weak/medium/strong/confirmed) + attacker addr. |
| $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.
