Turn serial devices into reusable, auditable tools for coding agents — discover, decode, visualize, capture, and replay.
Turn serial hardware into reusable, auditable tools for coding agents.
OpenBaud gives Codex structured access to local serial devices. Inside an agent task, it makes hardware actions visible and auditable, returns structured results instead of byte dumps, and turns verified exploration into durable tools. It combines an MCP server with device profiles, typed commands, workflows, lossless captures, byte-exact replay, and a hardware-exploration skill.

A serial terminal can send bytes. An ad-hoc script can make one device work. OpenBaud keeps the evidence that makes the result repeatable:
- Explore safely: identify ports by USB metadata, frame responses, audit writes, and require explicit acknowledgement for dangerous commands. - Sediment knowledge: turn verified behavior into typed, reviewable YAML commands and fixed workflows with provenance. - Parse real protocols: validate checksums and decode scalars, bit fields, split lists, and record arrays into structured results. - Replay without hardware: record every RX/TX byte in .obcap, then rerun the same command and parser against the capture.
The product video uses a physical ESP32-S3 development board running a new binary protocol, OBP/1. OpenBaud recorded eight hardware exchanges and decoded every 196-byte response into 36 polar points with CRC-16 verification.
The USB transport, board timestamps, frames, captures, and parsing are real. The radar scene is generated by the test firmware, and that fact is declared on the wire as simulatedscene: 1.
