A project command for adding support for a new laboratory instrument to the instrument-mcp server. The server connects AI tools to equipment such as oscilloscopes, logic analyzers, multimeters, and power supplies.

Creating a driver that can connect to, disconnect from, query, and send commands to a device. It also covers adding device-specific operations, a mock driver, server registration, and unit tests.

It gives a defined implementation path so a new device has the same connection, command, mock, registration, and test coverage as existing devices. A mock is a software stand-in that allows testing without the physical instrument.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00246
Opus 5.5	$0.00000	$0.00098
Sonnet 5.5	$0.00000	$0.00049
Haiku 4.5	$0.00000	$0.00025

Security

Grade A, and why

add-driver scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

새로운 장비 드라이버를 추가합니다.

입력

드라이버 정보: $ARGUMENTS (장비명, 연결 방식 등)

작업 절차

src/drivers/base.py의 InstrumentDriver ABC를 상속하는 새 드라이버 클래스 작성
필수 구현 메서드: connect(), disconnect(), query(), send_command()
해당 장비 전용 메서드가 있으면 추가 (예: Saleae의 capture(), decode_spi())
src/mock/에 대응하는 Mock 드라이버 작성 (같은 인터페이스)
src/server.py의 _create_drivers()에 등록
테스트 작성 및 실행: python -m pytest tests/unit/ -v

규칙

SCPI/VISA 장비는 VisaDriver를 바로 사용하거나 상속
비-VISA 장비(Saleae, Serial 등)는 별도 드라이버 클래스
연결 관련 에러는 ConnectionError로 통일
timeout, 재시도 정책은 CLAUDE.md 참고

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

add-driver is a command published in the GitHub repository mingyo186/instrument-mcp (0 stars, last pushed 8mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 246 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

Produce a complete, fab-ready export bundle for a routed board — or refuse loudly.
