knowledge-master 0.1.0

Local-first knowledge graph for developers. Your AI agent's permanent memory.

⚡ Knowledge Master

Your codebase's memory. A local knowledge graph that gives AI agents real understanding of your architecture — not just text search.

---

Why

Every time you start a new AI chat, it forgets everything. You re-explain your architecture, conventions, dependencies. Knowledge Master gives your AI permanent, structured memory about your entire system.

Unlike flat RAG tools that return "chunks about X", Knowledge Master builds a graph — so it can answer "what breaks if I change X?" by traversing actual relationships.

What it does

• 🔍 Semantic search across all your code, docs, and configs
• 🕸️ Knowledge graph — relationships between services, people, repos, technologies
• 💥 Blast radius — "what depends on this service/file/technology?"
• 📏 Convention enforcement — detects and enforces your team's patterns
• 🤖 MCP server — plugs directly into AI agents (Kiro, Claude, Cursor)
• 🖥️ Web UI — search, browse, visualize your knowledge graph
• 🔒 Local-first — nothing leaves your machine

Features

Semantic Search with Graph Context

$ km search "how does auth work"
┌────────┬──────────────────────┬─────────────────────┬──────────────────────┐

Blast Radius Analysis

$ km blast-radius auth-service
💥 Blast radius: auth-service
├── ⚙️ user-service (Service, via DEPENDS_ON)
├── ⚙️ payment-service (Service, via DEPENDS_ON)
├── 📦 frontend (Repo, via USES_SERVICE)
└── 👤 Alex (Person, via AUTHORED)

4 entities affected

Convention Enforcement

$ km check-conventions ~/my-project
  ✓ src/ directory (structure)
  ✓ separate test directory (testing)
  ✗ snake_case files (file-naming)
  ✓ Repository pattern (design-pattern)

1 convention(s) violated

Web UI & Graph Visualization

$ km serve
Knowledge Master UI → http://127.0.0.1:9999

Interactive force-directed graph showing your entire knowledge topology:

• 📦 Repos (blue) → 🔧 Technologies (red)
• ⚙️ Services (orange) → Dependencies
• 👤 People → Authorship
• 📏 Conventions (purple)

MCP Integration (AI Agents)

Add to your Kiro/Claude agent config:

{
  "mcpServers": {
    "knowledge": {
      "command": "km-server"
    }
  }
}

Your AI agent gets these tools:

• search — semantic search with graph context
• blast_radius — dependency analysis
• check_conventions — verify code follows team patterns
• index_repo — add new repos to the knowledge base

Development

# Run tests
pytest

# Lint
ruff check knowledge_master/

# Run MCP server directly
python -m knowledge_master.server

# Run CLI directly
python -m knowledge_master.cli status

Troubleshooting

Issue	Fix
km start fails with "Docker not running"	Start Docker: colima start (macOS) or sudo systemctl start docker (Linux)
km start fails with "Ollama not found"	Install Ollama from https://ollama.com and run ollama serve
km index is slow	First run downloads the embedding model (~274MB). Subsequent runs are fast.
Web UI shows "Connection refused"	Make sure containers are running: km start
Search returns poor results	Index more content. Quality improves with more context in the graph.
Port 9999 already in use	Use km serve --port 8888
