DRACO — The Book-Forged Code Oracle

Other AIs guess. DRACO knows — and proves it.

DRACO answers coding, systems, and security questions using retrieval over a library of 1,855 real technical books (354M characters, 116,558 indexed passages) — and cites the exact book behind every claim. No knowledge cutoff. No hallucination laundering. Receipts attached.

How it works

question ──► BM25 retrieval over 116k book passages
                │
                ▼
        top passages + question ──► local LLM (self-hosted GPU)
                │
                ▼
        answer with inline [n] citations + sources array

1. Ingest (ingest.py) — PDF/CHM/DJVU → clean plain text. Junk scans dropped automatically.

2. Index (build_index.py) — 300-token overlapping chunks → Snowball-stemmed BM25 index.

3. Serve (Flask + gunicorn) — retrieval-augmented generation with SSE streaming, separate reasoning and answer channels, and automatic degenerate-output detection/retry.

4. Expose — REST API, streamable-http MCP server, and a full agent-discovery kit: /llms.txt, /llms-full.txt, /openapi.json, /.well-known/ai-plugin.json, /.well-known/mcp-server.json, /sitemap.xml.

Pricing

Bitcoin only. No subscription traps, no KYC, no card processor.

1 credit = 1 ask or 1 search. Credits never expire. Books are free to download at /library — we sell answers, not files.

Self-hosting

git clone https://github.com/drjonesxxx1/draco.git
cd draco
python3 -m venv venv && ./venv/bin/pip install -r requirements.txt
cp config.example.json config.json   # set model, ollama URL, limits, payments

# point ingest.py at YOUR book directory, then:
./venv/bin/python3 ingest.py         # books → text + manifest
./venv/bin/python3 build_index.py    # text → BM25 index

./venv/bin/gunicorn -w 2 --threads 8 -b 127.0.0.1:8012 app:app    # API + web
./venv/bin/python3 -m uvicorn mcp_server:app --port 8013           # MCP

Any local Ollama model works. Put nginx in front (see deploy/nginx-draco.conf for the reference config incl. SSE + MCP proxying). Payments are optional — leave the btcpay block empty and the free tiers carry the whole thing.
