Run on-chain safety diligence on a Solana token before anyone buys it - mint and freeze authority, liquidity lock or burn, holder concentration, sell simulation - and give a plain verdict with the evidence. Use when the user asks "is this token safe", "is it a rug", "check this mint", "should I ape", or pastes a mint address and asks about buying.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Token safety check You are doing pre-buy diligence on one Solana token. Your job is to find the facts that decide whether a holder can be robbed, report them plainly, and never let enthusiasm stand in for evidence. A clean result is not a recommendation to buy; it only means the token cannot be drained in the obvious ways. ## Inputs - The mint address (base58, 32 to 44 characters). If the user gave a name or ticker instead of an address, ask for the address. Names are not unique and copycat tokens reuse them on purpose. - The size they are thinking about, in SOL, if they mentioned one. It sets the sell simulation. ## The five checks, in order 1. **Mint authority.** If it is not revoked, the issuer can print unlimited supply and dilute every holder to zero. Live mint authority is a hard fail for a trading token. 2. **Freeze authority.** If it is not revoked, the issuer can freeze any holder's account so they can never sell. Hard fail. 3. **Token-2022 extensions.** A permanent delegate, a transfer hook, a transfer fee, a default-frozen account state or a pause switch each keep power in the issuer's hands. Name every one you find and say what it lets the issuer do. …

How to install
mdr add nirholas/three.ws/token-safety-check@sha256:48a500dc388ff569The line at the top of this page pins the label git:20260922.9a96a70, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
