About this server
Coding & security oracle grounded in 1855 real books. Cited answers via MCP.
Install DRACO — The Book-Forged Code Oracle
The server’s own address, for the clients that take one directly. Or connect ahel once and every client you use reads it from one address, with the account kept on ahel rather than in each client’s config.
Claude Code
claude mcp add --transport http --scope user draco-the-book-forged-code-oracl 'https://draco.thetempleofdoom.com/mcp'Run it once in your project, then open /mcp to approve any sign-in the server asks for.
Claude Desktop

From the project's README
As published by drjonesxxx1/draco in README.md.
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.
Try it now: https://draco.thetempleofdoom.com — 10 free questions a day, no signup.
Why it's different
| Generic chatbot | DRACO |
|---|---|
| Compressed training-data recall | Live retrieval from 1,855 books on the shelf |
| "Trust me" answers | Every claim carries [n] citations + a sources array |
| Knowledge cutoff: yes | The canon is resident — K&R, Tanenbaum, the shellcoders' handbook |
| Sells your prompts | Self-hosted, zero telemetry, questions never leave the house |

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
- Ingest (
ingest.py) — PDF/CHM/DJVU → clean plain text. Junk scans dropped automatically. - Index (
build_index.py) — 300-token overlapping chunks → Snowball-stemmed BM25 index. - Serve (Flask + gunicorn) — retrieval-augmented generation with SSE streaming, separate reasoning and answer channels, and automatic degenerate-output detection/retry.
- 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.

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.
