Quillrag MCP Server
One file. Zero dependencies. Ready before your editor finishes loading. A local RAG engine in a single static binary - MiniLM embeddings compiled inside, hybrid dense + BM25 retrieval, MCP-native. No Node, no Python, no model download on first query. Its README documents 4 tools, including rag_index, rag_search, rag_status.
People who work with embeddings, local first and rag and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.

Security posture
What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.
repo age created 2026-08-25 - young repo, little track record yet
license MIT - declared in the repository

The 4 tools it gives your agent
Extracted from the project's README - what quillrag lets an agent do.
- rag_index
- - Incrementally index a directory/file. Skips unchanged files, re-embeds only diffs. Pruning is scoped to the directory you pass: docs indexed from other roots ar
- rag_search
- - Hybrid retrieval: dense MiniLM cosine + BM25 keyword, fused with Reciprocal Rank Fusion. Returns ranked chunks with source paths.
- rag_status
- - Document/chunk counts, bytes indexed, file-type breakdown.
- rag_clear
- - Wipe everything.
