## Tools

21 declared. Statically extracted from the shipped source — a floor on the surface, not a census.
- `list_connected_boards` — List connected boards and serial ports detected by arduino-cli.
- `arduino_cli_doctor` — Check whether arduino-cli is available and return OS-specific installation instructions if missing.
- `install_arduino_cli` — Attempt to install arduino-cli for the current OS using available package managers, then verify and configure CLI path.
- `list_supported_boards` — List supported/installable boards from the local arduino-cli index.
- `ensure_core_installed` — Ensure the Arduino core required by a board FQBN is installed. Can auto-install via `arduino-cli core install`.
- `detect_hardware` — Detect connected Arduino-compatible hardware, infer board/FQBN candidates, and generate next compile/upload commands.
- `list_serial_ports` — List serial ports and any detected board metadata using arduino-cli. Works on Windows/macOS/Linux.
- `compile_sketch` — Compile an Arduino sketch with a specific board FQBN.
- `upload_sketch` — Upload a compiled sketch to a connected board/port.
- `upload_and_wait_ready` — Upload a sketch and wait for a serial readiness pattern, handling post-upload reset/re-enumeration windows.
- `read_serial_snapshot` — Capture serial output for a bounded duration from a given port.
- `safety_preflight` — Run electrical preflight checks (voltage/current/pin risks) before upload or serial write operations.
- `serial_open_session` — Open a stateful serial monitor session with port lock ownership.
- `serial_list_sessions` — List active serial sessions and current port lock state.
- `serial_read` — Read buffered bytes from an open serial session.
- `serial_expect` — Wait for a string pattern in a serial session buffer with timeout.
- `serial_write` — Write bytes to an open serial session. Safety preflight is enforced unless explicitly skipped.
- `serial_close_session` — Close a serial session and release its port lock.
- `get_board_details` — Get detailed board metadata from arduino-cli for a specific FQBN.
- `list_board_reference` — List local board reference entries with pin/spec metadata.
- `search_board_reference` — Search local board reference by board name, alias, id, or FQBN.

## Install

**Verdict: review** — Installable, but 1 thing to check first: No publisher has proved control of this listing; it is indexed, not vouched for.
**Cautions** (coverage gaps and advisories — never blocking)
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"arduino-mcp-server\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"arduino-mcp-server\"\n      ]\n    }\n  }\n}"
```

## Blast radius

Moderate to extensive — no credential declaration found, from the publisher, the upstream registry, or the README. Known so far: mutates data; runs on your machine.
- Floor 33, ceiling 57 (tier: unknown)
- `unknown` means the floor and ceiling land in different bands — not measured enough to name one. It does not mean low.
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
