Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.
Remote servers are capped at 8.0 because source code is not available for review. The score reflects endpoint verification only.

On-chain rug-pull & honeypot risk screen for ERC-20 tokens β for AI agents and traders.
Give it a token address and get a SAFE / CAUTION / HIGH-RISK verdict (0β100 score) in one call, built entirely from live public-RPC reads β no API key, no node, no signup.
rug-check is an automated on-chain risk screen, not financial advice or a safety guarantee. It pattern-matches deployed bytecode and reads chain state; it cannot catch every scam (off-chain admin keys, novel honeypots) and may flag benign contracts. Always do your own research.
An AI coding/trading agent that "just reads the chain" does not know:
mint, blacklist, pause, setFees, setMaxTx β the levers used to trap or dilute holders.rug-check ABI-encodes and batches all of that, decodes the bytecode, scores it, and returns one verdict.
| Check | What it tells you |
|---|---|
| Owner powers | scans runtime bytecode for mint / blacklist / pause / setFees / setMaxTx |
| Ownership | renounced vs active owner (owner() / getOwner() β zero/dead = renounced) |
| Concentration | % of total supply held by the owner wallet |
| Liquidity | UniswapV2/Pancake pair reserves vs wrapped-native, depth, thin-liquidity flag |
| LP lock/burn | % of LP supply in burn address or known lockers (Pinksale, Unicrypt, Team.Financeβ¦) |
| Proxy | EIP-1967 upgradeable-proxy detection (behaviour can change post-launch) |
Chains: Ethereum, Base, BSC, Polygon, Arbitrum.
