@autodev/codebase

A vector embedding-based code semantic search tool with MCP server and multi-model integration. Can be used as a pure CLI tool. Supports Ollama for fully local embedding and reranking, enabling complete offline operation and privacy protection for your code repository.

🛠️ Quick Start

# Demo mode (recommended for first-time)
# Creates a demo directory in current working directory for testing

# Index & search
codebase index --demo
codebase search "user greet" --demo

# Call graph analysis
codebase call --demo --query="app,addUser"

# MCP server
codebase index --serve --demo

📋 Commands

📝 Code Outlines

# Extract code structure (functions, classes, methods)
codebase outline "src/**/*.ts"

# Generate code structure with AI summaries
codebase outline "src/**/*.ts" --summarize

# View only file-level summaries
codebase outline "src/**/*.ts" --summarize --title

# Clear summary cache
codebase outline --clear-summarize-cache

🔗 Call Graph Analysis

# 📊 Statistics Overview (no --query)
codebase call                           # Show statistics overview
codebase call --json                    # JSON format
codebase call src/commands              # Analyze specific directory

# 🔍 Function Query (with --query)
codebase call --query="getUser"         # Single function call tree (default depth: 3)
codebase call --query="main" --depth=5  # Custom depth
codebase call --query="getUser,validateUser"  # Multi-function connections (default depth: 10)

# 🎨 Visualization
codebase call --viz graph.json          # Export Cytoscape.js format
codebase call --open                    # Open interactive viewer
codebase call --viz graph.json --open   # Export and open

# Specify workspace (works for both modes)
codebase call --path=/my/project --query="main"

Query Patterns:

• Exact match: --query="functionName" or --query="*ClassName.methodName"
• Wildcards: * (any characters), ? (single character)
  • Examples: --query="get*", --query="*User*", --query="*.*.get*"
• Single function: --query="main" - Shows call tree (upward + downward)
  • Default depth: 3 (avoids excessive output)
• Multiple functions: --query="main,helper" - Analyzes connection paths between functions
  • Default depth: 10 (deeper search needed for path finding)

Supported Languages:

• TypeScript/JavaScript (.ts, .tsx, .js, .jsx)
• Python (.py)
• Java (.java)
• C/C++ (.c, .h, .cpp, .cc, .cxx, .hpp, .hxx, .c++)
• C# (.cs)
• Rust (.rs)
• Go (.go)

🔍 Indexing & Search

# Index the codebase
codebase index --path=/my/project --force

# Search with filters
codebase search "error handling" --path-filters="src/**/*.ts"

# Search with custom limit and minimum score
codebase search "authentication" --limit=20 --min-score=0.7
codebase search "API" -l 30 -S 0.5

# Search in JSON format
codebase search "authentication" --json

# Clear index data
codebase index --clear-cache --path=/my/project

🌐 MCP Server

# HTTP mode (recommended)
codebase index --serve --port=3001 --path=/my/project

# Stdio adapter
codebase stdio --server-url=http://localhost:3001/mcp

⚙️ Configuration

# View config
codebase config --get
codebase config --get embedderProvider --json

# Set config
codebase config --set embedderProvider=ollama,embedderModelId=nomic-embed-text
codebase config --set --global qdrantUrl=http://localhost:6333

🚀 Advanced Features

🔍 LLM-Powered Search Reranking

Enable LLM reranking to dramatically improve search relevance:

# Enable reranking with Ollama (recommended)
codebase config --set rerankerEnabled=true,rerankerProvider=ollama,rerankerOllamaModelId=qwen3-vl:4b-instruct

# Or use OpenAI-compatible providers
codebase config --set rerankerEnabled=true,rerankerProvider=openai-compatible,rerankerOpenAiCompatibleModelId=deepseek-chat

# Search with automatic reranking
codebase search "user authentication"  # Results are automatically reranked by LLM

Benefits:

• 🎯 Higher precision: LLM understands semantic relevance beyond vector similarity
• 📊 Smart scoring: Results are reranked on a 0-10 scale based on query relevance
• ⚡ Batch processing: Efficiently handles large result sets with configurable batch sizes
• 🎛️ Threshold control: Filter results with rerankerMinScore to keep only high-quality matches

Path Filtering & Export

# Path filtering with brace expansion and exclusions
codebase search "API" --path-filters="src/**/*.ts,lib/**/*.js"
codebase search "utils" --path-filters="{src,test}/**/*.ts"

# Export results in JSON format for scripts
codebase search "auth" --json

Path Filtering & Export

# Path filtering with brace expansion and exclusions
codebase search "API" --path-filters="src/**/*.ts,lib/**/*.js"
codebase search "utils" --path-filters="{src,test}/**/*.ts"

# Export results in JSON format for scripts
codebase search "auth" --json

⚙️ Configuration

Config Layers (Priority Order)

1. CLI Arguments - Runtime parameters (--path, --config, --log-level, --force, etc.)
2. Project Config - ./autodev-config.json (or custom path via --config)
3. Global Config - ~/.autodev-cache/autodev-config.json
4. Built-in Defaults - Fallback values

Note: CLI arguments provide runtime override for paths, logging, and operational behavior. For persistent configuration (embedderProvider, API keys, search parameters), use config --set to save to config files.

🔌 MCP Integration

HTTP Streamable Mode (Recommended)

codebase index --serve --port=3001

codebase index --serve --port=3001

# Then connect via stdio adapter in another terminal (for IDEs that require stdio)
codebase stdio --server-url=http://localhost:3001/mcp

{
  "mcpServers": {
    "codebase": {
      "command": "codebase",
