RugCheck AI

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

A lightweight MCP server that reads a Solana token's mintdirectly from the chainto screen for the common rug & honeypot trapsbeforeyour agent trades — active mint/freeze authority and dangerous Token-2022 extensions (permanent delegate, transfer hooks, non-transferable, pausable) — then, for tokens that pass, builds the buy as anunsignedJupiter transaction carrying a small Jito tip for faster inclusion. You sign it; the server never holds keys.

No install, no API key. Point your agent at the remote endpoint:

https://web-production-58d585.up.railway.app/mcp

scan_token("DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263") # BONK → { verdict: "SAFE", safety_score: 100, sellable: true, risks: ["no red flags found"] }

SAFE→ clear.CAUTION→ read the risks.DANGER→ don't buy. That's the whole loop.

Three real mainnet tokens, onescan_tokencall each (scanned 2026-06-17 — re-run to verify, live state changes):

The honeypot is the one that matters: you could buy it and never sell. RugCheck AI flags itbeforeyour agent spends a cent — even though the token is too new to be indexed anywhere else. Even USDC comes backCAUTION, notSAFE, because the issuer can still freeze your balance — the verdict tells you the truth, not a marketing label.

- scan_token— full safety report in one call: authority, Token-2022 traps, honeypot, liquidity & holder concentration → SAFE/CAUTION/DANGER + a 0–100 score
- is_safe— quick yes/no gate: one boolean before you trade
- verify_token_safety— on-chain audit: mint/freeze authority + Token-2022 traps + live market
- check_authorities— mint / freeze authority and extension detection
- simulate_sell— can the token actually be sold? (honeypot check)
- simulate_trade— full round-trip (buy then sell back): real entry/exit cost & round-trip loss %
- check_liquidity— DEX liquidity, 24h volume, age, buys/sells
- holders_breakdown— top-holder concentration (dump risk)
- token_age— freshness + real trading activity
- rug_forecast— heuristic rug ETA: probability + urgency window + factors
- scammer_dna— intent score (0–100): how much the token's structure looks like a deliberate scam
- check_deployer— the wallets that hold power over the token
- compare_tokens— rank a basket of tokens safest-first
- batch_scan— scan up to 10 tokens at once, one report each

- execute_safe_swap— re-screens the mint, then builds a Jito-tipped Jupiter swap (unsigned); refuses tokens that scan DANGER

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

Your agent needs to answer, before it spends a cent:

- Is this Solana token safe to buy — or is it a rug pull?
- Is this a honeypot — will I actually be able to sell after I buy?
- Does the mint have an active freeze / mint authority that can trap or dilute me?
- Is there a hidden Token-2022 trap (permanent delegate, transfer hook) that can drain me?
- Pre-trade screening / token due-diligence for an autonomous trading agent.

Built for AI trading agents, snipers and bots that buy SPL / Token-2022 tokens and need a fast on-chain rug check before entering — then a screened Jupiter route once a token clears.

How do I check if a Solana token is safe to buy?Callscan_token(mint)— one call returns a SAFE / CAUTION / DANGER verdict covering mint/freeze authority, Token-2022 traps, honeypot (sellability), liquidity and holder concentration, plus a 0–100 safety score.

How do I detect a honeypot before buying?simulate_sell(mint)checks whether a live sell route exists — a token with no route is effectively a honeypot even when nothing on-chain formally blocks selling.

How do I check holder concentration / whale dump risk?holders_breakdown(mint)reports the largest wallets and what share of supply they control — high concentration means one holder can crash the price on you.

How do I know if a token is a rug pull?rug_forecast(mint)gives a heuristic rug probability and urgency window from real signals (authority, Token-2022 traps, concentration, sell pressure, age).check_authoritiesandcheck_deployershow exactly who holds power over the token.

Does it work on fresh / newly launched tokens?Yes — it reads the mint directly on-chain (getAccountInfo), so you get a real verdict on a token too new to be indexed elsewhere.token_ageshows freshness and real trading activity.

Does it touch my wallet or sign anything?No. Screening is read-only;execute_safe_swaponly builds an UNSIGNED transaction for you to sign — the server never holds keys, never signs, never sends.

Is it free? Do I need an API key?Remote server, no install, no API key. Point your agent at the endpoint and call the tools.

v1.2.0 — working, actively developed, CI-tested. Open source, auditable — the screening tools are read-only (getAccountInfo);execute_safe_swaponly builds an unsigned transaction for you to sign.
