serial-mcp-server

The project demonstrates high security awareness with an explicitly panic-free runtime, structured error handling, and strict limitation of arbitrary file/process access to only serial ports. It leverages the `serialport` and `sqlx` crates for hardware and database interactions, which handle underlying OS permissions and use prepared statements (reducing SQL injection risk). Input from network interfaces (REST, WebSocket) is parsed and validated, with data intended for the serial port being passed as a conduit without server-side execution. Main risks would depend on the security of the connected serial device and the deployment environment, rather than direct vulnerabilities in the server's core logic.
