lore-mcp-server

MCP server for searching and reading lore.kernel.org mailing list archives.

No external dependencies beyond FastMCP — all lore.kernel.org interactions use the standard library (urllib, email, mailbox).

Tools

lore_search

Search lore.kernel.org using Xapian query syntax. Returns lightweight results (no message bodies) via the Atom feed API.

lore_search(
    query='bs:"guest_memfd" d:20260401..',
    mailing_list="kvm",
)

Supports public-inbox search prefixes: bs: (subject+body), s: (subject), f: (from), d: (date range), dfn: (diff filename), and more.

Use lore_get_message to fetch the full content of a specific result.

lore_get_message

Fetch the full content of a single message by URL.

lore_get_message(url="https://lore.kernel.org/kvm/20260420154720.29012-1-itazur@amazon.com/")

lore_get_thread

Fetch all messages in a thread by URL (with full bodies).

lore_get_thread(url="https://lore.kernel.org/kvm/20260420154720.29012-1-itazur@amazon.com/")

lore_list_thread_structure

List the structure of a thread without message bodies. Returns only headers and reply relationships (in_reply_to) for each message. Use this to get an overview of a large thread before fetching specific messages with lore_get_message.

The underlying mbox data is cached in-memory, so subsequent calls to lore_get_thread or lore_get_message for the same thread are served from cache without additional network requests.

lore_list_thread_structure(url="https://lore.kernel.org/kvm/20260420154720.29012-1-itazur@amazon.com/")
