Plexa MCP

An official MCP server for Plexa that provides economic-safety tools for trading agents. It exposes two tools: plexa_quote for retrieving executable liquidity and fill prices, and plexa_pretrade_check for verifying token safety against rugs and honeypots. Payments are handled automatically via the x402 protocol using a configured wallet, allowing agents to pay per call without holding API keys.
