If you're building autonomous trading agents on Solana, you've hit this problem: your agent needs to vet a token before it buys — but most agents trade blind. They have no idea whether a token is a rug pull, a honeypot, or has an active mint authority that can dilute holders to zero.
I built SolGuard to fix this: an MCP server that screens any SPL / Token-2022 token for the common scam patterns, then executes the swap through an MEV-protected route — screening and execution in one place.
What it checks
- Mint & freeze authority — is supply still mintable? Can your tokens be frozen in place?
- Honeypot detection — can the token actually be sold, or only bought?
- Liquidity & holders — concentration, LP locks, real depth.
- Token-2022 traps — permanent delegate, transfer hooks, default-frozen state.
Tools

Why pre-trade screening matters
A rug pull on Solana often looks fine at the moment of purchase — liquidity is there, the chart is green. The trap is in the authority: a live mint authority lets the deployer print unlimited supply after you buy; a freeze authority can lock your tokens so you can never sell. An autonomous agent that doesn't read these on-chain fields walks straight into it. SolGuard reads them directly and gives a verdict on a fresh launch instead of unknown.
Built for Solana trading agents. Feedback welcome.
