README

osdev-wiki-mcp

The OSDev wiki, offline and searchable, for your AI agent.

wiki.osdev.org is the reference for hobby operating-system development. It covers descriptor tables, paging, interrupt controllers, timers, ACPI, disk controllers, bootloaders and toolchains. Agents writing kernel code tend to reconstruct these details from memory and get bit layouts wrong. They also can't browse the wiki themselves, because it sits behind a bot challenge.

osdev-wiki-mcp downloads the wiki's public archive once, indexes it locally with SQLite full-text search, and gives the agent tools to search it, read a page or just one section of it, and follow links.

What it looks like

This is real output, from the 2025-12-30 dump:

> wiki_search("PIT", limit=3)

# Interrupt Descriptor Table
https://wiki.osdev.org/Interrupt_Descriptor_Table · last edited 2025-06-05 · categories: X86 CPU, Interrupts
('IDT' redirects to 'Interrupt Descriptor Table'; 'Gate Descriptor' appears 2 times; showing
section 4 under 'Structure on IA-32'. Also: section 8 under 'Structure on x86-64')

### Gate Descriptor

Each entry in the table has a complex structure:

Gate Descriptor (32-bit):
63..48 | 47 | 46..45 | 44 | 43..40 | 39..32
Offset 31..16 | P | DPL 1..0 | 0 | Gate Type 3..0 | Reserved
31..16 | 15..0
Segment Selector 15..0 | Offset 15..0

- Offset: A 32-bit value, split in two parts. It represents the address of the entry point ...
[... section truncated]

[Cut at max_chars=900; the full text is 1567 chars. Call again with max_chars=1767 to read the rest.]

Notice what the output does for the agent:

Abbreviations work. "PIT" and "IDT" are wiki redirects, and redirects are indexed as aliases of their target, so an abbreviation finds the right page first.
Bit-layout tables stay readable. The wiki draws descriptor and page-table layouts as HTML tables. These are rendered as one row per line, with bit ranges shown as 63..48.
Ambiguity is reported. When a heading appears twice on a page, the agent is told where the other copy is.
Truncation explains itself. A cut-off result says exactly what to call next.

Install

pip install osdev-wiki-mcp
osdev-wiki-mcp --update          # one-time: download (~5 MB) and index (~15 s)
claude mcp add osdev-wiki -- osdev-wiki-mcp

You can skip --update. The agent can call wiki_update itself: every other tool tells it to when there's no index yet.

The index (about 18 MB) lives in %LOCALAPPDATA%\osdev-wiki-mcp on Windows, ~/Library/Application Support/osdev-wiki-mcp on macOS, and $XDG_DATA_HOME/osdev-wiki-mcp (or ~/.local/share/osdev-wiki-mcp) elsewhere. Set OSDEV_WIKI_DIR to put it somewhere else. Python 3.10+ is required, with SQLite FTS5. python.org builds, uv-managed builds and most distro builds include FTS5, and the server tells you if yours doesn't.

Tools

Tool	What it does
`wiki_search`	Ranked full-text search with match snippets. Titles and redirect names count most, and an exact title match is marked `*`.
`wiki_sections`	A page's outline: numbered headings with their sizes.
`wiki_page`	A page as plain text, or one section (by number or heading) including its subsections. Code blocks are kept verbatim and redirects are followed.
`wiki_links`	What a page links to (flagging links to pages that don't exist) and what links to it, including links made through a redirect.
`wiki_update`	Fetch the newest dump and rebuild
