OpenBaud: MCP Server for Auditable Serial Hardware Access by Coding Agents
OneMasterpiece1717 · reddit · 2026-08-25
- Definition: OpenBaud is an open-source Rust MCP server and CLI designed to give coding agents auditable access to real serial and USB hardware.
- Key Features: Provides transparency on bytes sent and why. Agents can preserve raw captures, validate framing/checksums, parse typed fields, and convert interactions into reviewable YAML commands.
- Safety: Writes are audited, and dangerous commands require explicit acknowledgement.
- Demo: Uses a physical ESP32-S3 with a CRC-protected binary protocol. The repo includes a byte-exact capture for hardware-free replay.
