base-flash-arb-mcp
MCP server for detecting flash loan arbitrage opportunities across DEXes on Base mainnet.
Tools
Tool | Description |
| Compare token prices across Uniswap V2, V3, and Aerodrome. Find profitable arb routes. |
| Get reserves/liquidity for a token across all known DEX pools on Base. |
| Estimate flash loan profit between two pools after gas costs. |
| Scan top traded tokens on Base for arb opportunities via DexScreener. |
| Get current price of a token on all available DEXes. |
| Analyze recent trades for sandwich attack patterns (bot activity). |
| Check pending transactions for front-run detection. |
Install

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.
