boot-doctor-mcp
A real MCP server for PC no-boot / no-display / no-POST troubleshooting. No LLM guessing at hardware causes — a plain, deterministic rule engine plus real, sourced BIOS beep-code tables.
Why deterministic, not an LLM
Nobody wants a language model hallucinating "your GPU is dead" when it isn't. Hardware advice where being wrong costs real money and real time deserves a fixed, auditable rule set, not a plausible-sounding guess. Every answer this tool gives traces back to a real source or a fixed, testable rule — never an invented explanation.
Tools
diagnose_symptoms(powers_on, fans_spin=None, fans_stay_running=None, display_output=False, tried_cmos_reset=False, tried_minimal_config=False, tried_different_cable_or_monitor=False)
Real, ranked next troubleshooting steps, given what's already been tried — the same power-stage → CMOS reset → minimal-config-test → swap-test sequence a real technician runs, ordered by what's cheapest to rule out first. Not a diagnosis of the exact broken part; a real repair often still needs a swap test against known-good parts, and this tool says so explicitly rather than pretending symptom-matching alone can replace it.
lookup_beep_code(bios_type, pattern)
Looks up a beep pattern (e.g. "10 short", "1 long, 2 short", "continuous") against real, sourced BIOS beep-code tables.
bios_type is one of:
ami_legacy— classic AMIBIOSami_aptio— modern AMI Aptio (UEFI), kept separate on purpose: legacy AMIBIOS and Aptio use genuinely different codes for the same beep counts, a mistake common in beginner troubleshooting guides that merge them into one tableaward_phoenix— Award/Phoenix BIOS
Returns real information, not a fabricated guess, when the exact pattern isn't in the table — modern boards increasingly have no speaker at all and use debug LEDs instead, so "no match" is itself a real, honest result.
Sources
Beep-code data fetched and cross-referenced live (not from training-data memory) from IONOS and Thomas-Krenn. Real, stated limitation: OEMs (HP, Dell, ASUS, etc.) sometimes customize or extend these codes, and modern boards increasingly skip the speaker entirely in favor of debug LEDs — a documented pattern not matching here doesn't necessarily mean nothing is wrong.
Install
pip install boot-doctor-mcp
Add to your MCP client config (e.g. Claude Code):
claude mcp add boot-doctor-mcp -- boot-doctor-mcp
Or run directly for local testing:
python -m boot_doctor_mcp.server
Development
pip install -e ".[dev]"
pytest
