PickleCheck MCP
Provides three safety checks for AI trading agents on Base: scam checks for Base tokens and wallets, endpoint checks for x402 services, and payment verification across multiple chains. It offers daily free calls and uses USDC on Base for subsequent payments via x402.
Endpoint and access
No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.
https://picklecheck.onrender.com/mcpWhat you can do with it
- Check if a Base token is a rug, honeypot, or insider dump
- Verify if an x402 endpoint is safe to pay
- Confirm if a payment transaction landed on-chain
- Check wallet safety against sanctions and blacklists
