Kernel Lore MCP

Kernel Lore MCP exposes structured search over the public Linux kernel mailing-list archives at lore.kernel.org to developer tools that speak the Model Context Protocol.

The system combines a Rust ingestion and indexing core with Python bindings and supports metadata, trigram code search, BM25 prose search, optional embeddings, patch-series analysis, author footprints, and git-backed merge or stable-backport checks. Status responses report corpus freshness and which optional tiers are actually provisioned, so a missing result can be distinguished from missing coverage.

Local deployments require no authentication or external API key. Operators can index a small subsystem slice or mirror the full lore corpus, depending on available disk and update time.
