Quick Start

CLI (recommended)

npx codebase-intelligence overview ./src

Common workflows:

npx codebase-intelligence hotspots ./src --metric complexity --limit 10
npx codebase-intelligence impact ./src parseCodebase
npx codebase-intelligence dead-exports ./src --limit 20
npx codebase-intelligence changes ./src --json

MCP (optional)

claude mcp add -s user -t stdio codebase-intelligence -- npx -y codebase-intelligence@latest .

Features

• 15 CLI commands for architecture analysis, dependency impact, dead code detection, and search
• Machine-readable JSON output (--json) for automation and CI pipelines
• Auto-cached index in .code-visualizer/ for fast repeat queries
• 11 architectural metrics — PageRank, betweenness, coupling, cohesion, tension, churn, complexity, blast radius, dead exports, test coverage, escape velocity
• Symbol-level analysis — callers/callees, symbol importance, impact blast radius
• BM25 search — ranked keyword search across files and symbols
• Process tracing — detect entry points and execution flows through the call graph
• Community detection — Louvain clustering for natural file groupings
• MCP parity (secondary) — same analysis available as 15 MCP tools, 2 prompts, and 3 resources

Installation

Run directly with npx (no install):

npx codebase-intelligence overview ./src

Or install globally:

npm install -g codebase-intelligence
codebase-intelligence overview ./src

CLI Usage

codebase-intelligence <command> <path> [options]

Commands

Useful flags

For full command details, see docs/cli-reference.md.

MCP Integration (Secondary)

Running without a subcommand starts the MCP stdio server (backward compatible):

npx codebase-intelligence ./src

Claude Code (manual)

Add to .mcp.json:

{
  "mcpServers": {
    "codebase-intelligence": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "codebase-intelligence@latest", "./src"],
      "env": {}
    }
  }
}

Cursor / VS Code

Add to .cursor/mcp.json or .vscode/mcp.json:

{
  "servers": {
    "codebase-intelligence": {
      "command": "npx",
      "args": ["-y", "codebase-intelligence@latest", "./src"]
    }
  }
}

For MCP tool details, see docs/mcp-tools.md.

        +--> MCP stdio (optional mode)

1. Parser — extracts files, functions, and imports via TypeScript Compiler API.
2. Graph — builds dependency/call graphs with graphology.
3. Analyzer — computes file/module/symbol metrics.
4. Interfaces — CLI is primary; MCP is available for agent integrations.

Requirements

• Node.js >= 18
• TypeScript codebase (.ts / .tsx files)

Limitations

• TypeScript-focused analysis
• Static analysis only (no runtime tracing)
• Call graph confidence varies by symbol resolution quality

Release

Publishing is automated through GitHub Actions.

Normal CI (before release)

• CI workflow runs on every PR and push to main:
  • lint → typecheck → build → test

Canary publish

• Pushes to main trigger a canary publish.
• The package is published to npm with the canary tag.
• Canary versions are derived from the current package version plus the short commit SHA.

Create a release

1. Bump package.json version in a normal PR.
2. Merge that PR to main.
3. Run the Publish workflow manually from GitHub Actions.
4. The workflow will:
   • verify the tag does not already exist
   • create and push vX.Y.Z
   • publish to npm with provenance via OIDC
   • create a GitHub Release with generated notes

No PAT is required for npm publish. The workflow uses GitHub repository permissions for tagging and OIDC for npm publishing.
