What it does
MCP server that provides economic-safety tools for trading agents on Base, Polygon, and Arbitrum. It offers executable price quotes and pretrade checks (rug/honeypot detection) via the Plexa API, with payment handled automatically through x402 protocol using USDC from a local wallet.
- Get executable fill prices and price impact for token swaps under a specified size before executing trades.
- Check if a token is a rug pull, honeypot, or has thin liquidity traps before buying, with on-chain verified verdicts and risk metrics.
- Integrate economic safety checks into trading agents with per-call payment in USDC without creating accounts.

Before you enable it
An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
