Chronicle MCP — Knowledge Graph

Self-learning code analysis tool for Claude Code. Builds a knowledge graph of your codebase — data models, services, endpoints, dependencies — and answers questions like "what breaks if I change X?"

Install

npm install -g @alexdx/chronicle-mcp

Setup with Claude Code

Add to your Claude Code MCP config (~/.claude.json):

{
  "mcpServers": {
    "chronicle": {
      "command": "chronicle",
      "args": ["mcp", "serve"]
    }
  }
}

Usage

Open Claude Code in any project and say:

chronicle scan          — Full project scan
chronicle data          — Analyze data models
chronicle language      — Domain language glossary
chronicle impact X      — What breaks if I change X?
chronicle deps X        — What depends on X?
chronicle services      — Service architecture
chronicle status        — Dashboard URL + graph stats

What it does

• Scans your codebase (NestJS, Prisma, GraphQL, Kafka, etc.)
• Builds a multi-layered knowledge graph (data → code → contracts → services)
• Tracks dependencies, impact paths, domain language
• Self-learns: discovers patterns, reports gaps, improves with each scan
• Admin dashboard with visual graph at http://localhost:<auto-port>
