serial-mcp-server gives AI workflows access to serial ports in two forms: an MCP stdio server for clients that support tools, and a scriptable CLI for direct use, continuous integration and agent skills where no MCP client is configured. The base capability is opening a serial port at a given baud rate, writing to it and reading responses, which covers interactive debugging of a microcontroller, modem or instrument. The distinctive addition in the 0.3.0 release is a JSON macro domain-specific language for automation: a macro pack describes a repeatable procedure as a sequence of writes, expected responses and timed waits, and can be validated, listed, planned and run — from the CLI with macro subcommands, or through MCP tools that load, list and unload packs in memory at runtime. Timing is the reason this matters, since serial device interaction is full of send-then-wait sequences that are tedious and error-prone to drive one call at a time. An explicit no-hardware simulation mode allows macro validation, planning and executor smoke tests without a device attached, which makes the macros testable in continuous integration. It is Rust on the official Rust MCP SDK, requires Rust 1.74 or newer, is MIT licensed, and ships Claude Code and Codex skills. The audience is embedded and hardware engineers.
