Common questions

Is Acpi MCP safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 34 days ago, and the latest version (0.1.0) reached the registry 34 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

acpi-mcp

Let your AI agent read the firmware's ACPI tables and tell you what they mean.

acpi-mcp is an MCP server that reads ACPI tables and explains them for OS developers. It covers how many CPUs there are and their APIC IDs, where the I/O APIC lives, which ISA IRQs are remapped, where the HPET and PCIe config space are, and the exact port writes that power the machine off or reset it.

It reads tables from three places:

  • a live QEMU guest, out of guest physical memory through QEMU's gdbstub (works even after the guest turns on paging);
  • a directory of table files: Linux's /sys/firmware/acpi/tables, or acpidump -b output from any machine;
  • optionally, AML disassembly with iasl if you have it installed. Nothing else needs it.

Companion to qemu-mcp (boot and drive the VM) and gdbstub-mcp (debug the kernel).

What it looks like

This is real output from QEMU 11 (-M q35 -smp 2), read live from the guest:

> acpi_table MADT

MADT revision 3: local APIC base 0xfee00000 (dual 8259 PICs present: mask them before using the APIC) 2 usable CPU(s), APIC IDs [0, 1] The BSP is usually APIC ID 0; start the others with INIT-SIPI-SIPI I/O APIC id 0 at 0xfec00000, GSI base 0 Interrupt source overrides (legacy ISA IRQ -> GSI): IRQ0 -> GSI 2 (I/O APIC 0 pin 2), bus default, bus default - this is why the PIT timer shows up on I/O APIC pin 2, not 0 IRQ9 -> GSI 9 (I/O APIC 0 pin 9), active high, level - non-ISA polarity/trigger: program the redirection entry to match ... Local APIC NMI on LINT1 for all CPUs (bus default, bus default) - program LVT LINT1 as NMI

acpi_find "how do I shut down the machine?"

Soft power-off (S5): \_S5_ = SLP_TYPa 0, SLP_TYPb 0

  1. If SMI_CMD (0xb2) is non-zero and SCI_EN (bit 0 of PM1a_CNT) is clear, enable ACPI: outb(0xb2, 0x2) and wait for SCI_EN
  2. outw(0x604, 0x2000) # SLP_TYPa << 10 | SLP_EN (bit 13)

acpi_find "reboot"

Reset: write 0xf to I/O port 0xcf9 (8-bit) (FADT RESET_REG, RESET_REG_SUP set). Fall back to the 8042 if it returns.

acpi_find "pci config space"

MCFG: PCI Express ECAM (memory-mapped config space) segment 0, buses 0-255: base 0xb0000000 (256 MiB) config address of bus B, device D, function F, offset O = 0xb0000000 + ((B - 0) << 20 | D << 15 | F << 12 | O)

acpi_table DSDT

8491 bytes of AML bytecode, 37 Device objects Recognised devices: \_SB_.PCI0 PNP0A08 (compatible PNP0A03) PCI Express host bridge \_SB_.HPET PNP0103 HPET \_SB_.PCI0.SF8_.KBD_ PNP0303 PS/2 keyboard (8042) \_SB_.PCI0.SF8_.COM1 PNP0501 16550 serial port (COM) ...

The recipes are tested, not just printed. The integration tests write the exact instructions acpi_find prescribes into a live guest, run them, and check the result: the shutdown recipe powers off both -M pc and -M q35, and the reset recipe resets q35. A control case that only runs hlt keeps running.

Why

ACPI is the first wall every hobby OS hits after "hello world". You need it for SMP, the I/O APIC, the HPET, PCIe and power-off. The tables are binary structures spread across firmware memory, the spec runs to over a thousand pages, and the bugs are silent: miss the IRQ0 → GSI2 override and your timer simply never fires. This server reads the tables your firmware actually built and answers in terms of what to program.

As far as I could find, no other MCP server reads or explains ACPI tables.

Install

pip install acpi-mcp

claude mcp add acpi -- acpi-mcp

Usage

Start QEMU with its gdbstub (-s). -S is fine, because acpi-mcp lets the firmware run until the tables exist:

qemu-system-x86_64 -M q35 -smp 2 -kernel kernel.elf -s -S

Then ask your agent something like *"load the ACPI tables from the VM on port 1234 and tell me how to route the keyboard interrupt through the I/O APIC"*.

On a Linux machine you can read its own tables (as root):

acpi_load(name="host", path="/sys/firmware/acpi/tables")

Tools

ToolWhat it does
acpi_loadLoad tables under a name from port= (live VM; boot_wait_s lets firmware run first; resume chooses whether the guest runs on afterwards) or from path= (a directory).
acpi_tablesList every table: address, length, checksum, OEM, and what the table is for.
acpi_tableDecode one table and explain it: FADT, MADT, HPET, MCFG, DSDT/SSDT, FACS, RSDT/XSDT, WAET, RSDP.
acpi_interrupt_routingMap ISA IRQs 0-15 to GSI and I/O APIC pin, with polarity and trigger mode.
acpi_findAnswer OS-dev questions: shutdown, reset, HPET, PCI config, CPUs, IRQ routing, PM timer, keyboard, serial, RTC century, SCI.
acpi_dumpHexdump a table's raw bytes.
acpi_disassembleAML to ASL with iasl -d, if installed.
acpi_setsList loaded table sets.

How it reads a live VM

  1. It connects to the gdbstub. QEMU pauses the guest while a debugger is attached.
  2. It switches the stub to physical memory with QEMU's Qqemu.PhyMemMode:1, so ACPI's physical pointers work even when the guest has paging on. On stubs without this packet it reads virtual addresses and says so in the output.
  3. It searches the EBDA and 0xE0000-0xFFFFF for a checksummed RSD PTR , then walks the XSDT (or RSDT), the FADT, the DSDT and the FACS.
  4. If the CPU hasn't run the firmware yet (-S), it runs the guest in short bursts until a complete, checksum-valid table set exists. It returns as soon as one does.
  5. It detaches with D;1, and the guest continues. Pass resume=False to leave it paused, for example before attaching gdbstub-mcp to a -S VM. QEMU allows only one debugger at a time.

Limits

  • The AML reader is a structured walker, not an interpreter. It parses the Scope, Device and Name objects that describe devices and skips Method bodies. Anything a method computes at runtime, such as a _STA that hides a device, isn't evaluated. If it ever has to fall back to byte-scanning a region (an If at scope level), the output says so. Use acpi_disassemble (iasl) for an exact listing.
  • UEFI guests (OVMF) pass the RSDP to the OS through the EFI system table, not the BIOS area, so the live search won't find it. Load those tables from a directory (acpidump -b) for now.
  • x86 only for now. ARM's ACPI (GICC/GICD in the MADT, GTDT) is on the backlog.

Tests

pip install ".[test]" "ruff==0.16.0" "mypy==2.3.0"

ruff check src tests && mypy --strict src pytest tests

The unit tests run on real tables captured from QEMU (tests/fixtures/tables/), so they need no QEMU. tests/test_qemu_integration.py reads live tables from i386 and x86_64 guests on both pc and q35, checks that the CPU count follows -smp, checks resume semantics, and runs the shutdown and reset recipes inside the guest. It skips any QEMU binary that isn't installed.
