deepDDW — Memory & Knowledge Base for DeepSeek Harness, Reachable from Any Device on Your LAN

Not just memory — a team-ready AI workstation on your LAN.

Extends DeepSeek Harness (DSH) with memory, a knowledge base, and LAN deployment — built on our production-grade DDW AI HUB platform.

• ✅ Breaks DSH's "local-only" limit — usable from any device on your LAN
• ✅ Memory + Knowledge Base + Document Search — via DSH's official standard MCP interface; DSH source untouched
• ✅ Packaged, easy to deploy, low ops cost — ready for small businesses up to ~20 people

💡 What makes deepDDW different from memory-only plugins: many DSH extensions give you memory alone. deepDDW is a complete workstation — memory + knowledge base + document search + LAN-wide multi-device access, packaged from a production-grade AI platform. Deploy once, your whole team uses DSH from their own devices.

Who We Are: Not Just an Open-Source Tool — a Commercial-Grade Solution

deepDDW is built on DDW AI HUB, a production-grade AI platform validated in enterprise deployments. We packaged that mature platform capability into the DSH ecosystem, addressing three key gaps that many open-source projects have not yet covered:

In one sentence: turn a "personal toy" into a tool a small team can actually use — fully packaged, easy to deploy, low maintenance, ready for small businesses (up to ~20 people) for their daily AI workflow.

How It Works (Technical Path)

📱 Phone / 💻 Desktop / 📱 Tablet / 🖥️ Laptop — any device on the LAN
   │                  (browser access, no App install)
   ▼
deepDDW Gateway (one server on the LAN)
   ├─ /dsh/*   proxy → DSH engine (official UI, model config & chat untouched)
   ├─ /api/*   proxy → DSH RPC/API
   └─ /api/v1/*  deepDDW capabilities: Knowledge Base / Memory / Docs / LLM config
        │
        │  DSH official MCP client (streamable-http)
        ▼
deepDDW MCP tools (auto-invoked by the model)
   ├─ mcp__deepddw__ddw_kb_search          knowledge base search
   ├─ mcp__deepddw__ddw_memory_put         write memory
   ├─ mcp__deepddw__ddw_memory_search      search memory
   └─ mcp__deepddw__ddw_docs_portal_search document search

Integration = DSH standard MCP: DSH natively supports MCP clients; deepDDW exposes a standard streamable-http endpoint — zero intrusion, zero changes to DSH source. The UI, settings and model configuration all remain official.

Why Does It Work on Your LAN?

The official DSH listens on localhost only (for security), so phones/tablets cannot connect. deepDDW solves this with gateway proxying:

• DSH stays bound to localhost (official security design preserved)
• deepDDW gateway listens on the LAN, any device opens http://<server-ip>:8600/ to reach the original DSH workbench
• All data stays on your server — never leaves the LAN

Deploy once, the whole family/team can use it — a capability the official DSH does not provide.

Quick Start

# 1. Install DSH (official) on the server
npm i -g @deepseek-ai/dsh

# 2. Install deepDDW (packaged, one command)
git clone https://github.com/ccch713/deepddw.git
cd deepddw && ./install.sh --with-dsh

# 3. Start
./install.sh --port 8600

# 4. Open from any device on the LAN:
#    http://<server-ip>:8600/   → original DSH workbench
#    Phones/tablets: "Add to Home Screen" for an App-like experience

# 5. Add your API Key in DSH Settings → Models
# 6. In chat, ask the model to "search the knowledge base" or "remember ..."
#    → it auto-invokes the mcp__deepddw__* tools

Requirements: one ordinary computer/server (8 GB RAM minimum, 16 GB+ recommended), Python 3.11+, no GPU needed (LLM via cloud API or local Ollama).

Ecosystem & Feedback

• Extend with official DSH plugins: deepDDW keeps DSH's native plugin mechanism intact. Install official plugins straight from the npm registry via the DSH official command — the only channel we recommend, to avoid supply-chain poisoning:

  dsh plugin --profile web add <npm-package>   # official npm registry only

  See SECURITY.md for our third-party plugin disclaimer and what deepDDW guarantees (memory & knowledge base only; no data theft/exploitation/sale).

• Knowledge distillation: use whatever distillation skill / workflow you prefer — the methodology is yours; deepDDW provides the complete pipeline "distilled output → searchable knowledge base → model-usable". More plugins and tools are on the way.
• Memory / knowledge migration: knowledge base uses standard SQLite; memory is organized by namespace/key/value — import from other agents or tools.
• Feedback: we'd love to hear how you use it; stronger open-source tools are coming in future releases.

Roadmap

• [ ] Docker one-click deployment (in progress, simpler install)
• [ ] Remote access while traveling: securely reach your company's DSH server from mobile devices, capture and discuss ideas anytime
• [ ] Session → document auto-ingest: conversation output auto-saved, searchable and traceable
• [ ] Vector search enhancement (optional, requires an embedding model)

deepDDW — enterprise-grade capability, open-sourced for everyone.
