Solana Security Standard MCP Server

The same SOL-0XX rules flag Solana-specific bugs while you code - caller-controlled clock values, cross-market state asymmetry, wrapper handlers that drift from engine logic, missing Anchor constraints, and 52 bug classes in all, drawn from real audits. It runs locally over stdio via the published package.

People connecting security tools to Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.
