🛡️ RugCheck AI — On-chain Token Safety for Solana AI Agents

A lightweight MCP server that reads a Solana token's mint directly from the chain to screen for the common rug & honeypot traps before your agent trades — active mint/freeze authority and dangerous Token-2022 extensions (permanent delegate, transfer hooks, non-transferable, pausable, default-frozen) — then executes the buy through an MEV-protected route.

Tools

• verify_token_safety — on-chain audit: mint/freeze authority + Token-2022 traps
• check_authorities — mint / freeze authority and extension detection
• simulate_sell — can the token actually be sold? (on-chain block check)
• execute_safe_swap — screens the output token, then builds a gas-optimized, MEV-protected (Jito) Jupiter swap, returned unsigned

Why

Most agents trade Solana tokens blind. RugCheck AI calls getAccountInfo on the mint and reads the authorities and Token-2022 extensions itself, so you get a real verdict on a fresh launch instead of unknown — and a live mint or freeze authority is flagged before you buy, not after.

Status

v1.0.0 — working, actively developed. Open source, auditable — the screening tools are read-only (getAccountInfo).
