MCP server for detecting flash loan arbitrage opportunities across DEXes on Base mainnet.

get_pool_reserves |
Get reserves/liquidity for a token across all known DEX pools on Base. |
estimate_flash_profit |
Estimate flash loan profit between two pools after gas costs. |
scan_top_tokens |
Scan top traded tokens on Base for arb opportunities via DexScreener. |
get_price_across_dexes |
Get current price of a token on all available DEXes. |
check_sandwich_risk |
Analyze recent trades for sandwich attack patterns (bot activity). |
get_mempool_pending |
Check pending transactions for front-run detection. |

DEXes Covered
- Uniswap V2 (Factory:
0x8909Dc15e40173Ff4699343b6eB8132c65e18eC6) - Uniswap V3 (Fee tiers: 0.05%, 0.3%, 1%)
- Aerodrome (Volatile + Stable pools)
How It Works
All tools are read-only -- no private key needed. The server queries on-chain pool reserves, uses DEX quoters for accurate pricing, and compares across exchanges to find price discrepancies that could be exploited via flash loans.
Flash profit estimation accounts for:
- Aave flash loan fee (0.09%)
- Base gas costs (dynamically estimated)
- Slippage warning
Sandwich detection uses heuristic analysis of Swap events to identify same-block multi-transaction patterns from single addresses.
