OmniClip RAG MCP Server

Read-only local-first MCP server for private Markdown, PDF, and Tika-backed search on Windows.

The short version

Caelune builds searchable indexes from knowledge you already keep on your own computer. It combines exact-text retrieval, structural signals, semantic vector search, optional reranking, and source-aware context assembly.

• Local-first storage — — indexes, configuration, models, logs, and Runtime payloads stay under the active local data root
• Markdown and Logseq awareness — — understands Markdown content plus common Logseq properties, block references, and embeds
• Hybrid retrieval — — combines SQLite FTS5, structure-aware scoring, LanceDB vector search, BAAI/bge-m3, and optional BAAI/bge-reranker-v2-m3
• PDF and Tika extensions — — maintains separate extension indexes and returns unified results with explicit source labels. The Tika catalog exposes 1,290 format entries; real compatibility still depends on the source file and parser
• Event-driven live watch — — reacts to real file changes, waits for the configurable quiet period, and performs incremental updates in disposable worker processes
• Visible query stages — — preparing, lexical recall, semantic recall, fusion, reranking, finalization, and context packing remain visible in the Query Console
