Indexa — Code Intelligence Engine

Stop reading code manually. Ask Indexa, click the answer, jump to the line.

Indexa is a context engine that sits between your codebase and your brain. It indexes your code once, then lets you search, trace execution flows, and find references — all from a sidebar in VS Code.

What It Does

Most tools help you find code. Indexa helps you understand it.

Features

Sidebar Search

Type a question, get structured results. Click any result to jump to the exact line.

Execution Flow Tracing

See the full call chain for any function or component — across files, with one query.

Find References & Blast Radius

Know what breaks before you change it. See every file affected by a symbol.

Type-Aware Results

Functions, components, services, hooks — each with its own icon and label. Results are grouped by Context, Dependencies, and Connections.

One-Command Setup

npx indexa-mcp setup

Indexes your codebase, configures MCP for Claude Code, and you're ready.

Quick Start

1. Install this extension
2. Open a terminal in your project and run:

   npx indexa-mcp setup
   

3. Click the Indexa icon in the sidebar
4. Try: "explain the auth flow"

Keyboard Shortcuts

How It Works

Your Code → Indexa indexes it → You ask a question → Get exact answers

Indexa uses:

• ML embeddings (Transformers.js) for semantic search
• BM25 for keyword matching
• AST parsing for structural understanding
• Dependency graphs for relationship tracking

All runs locally. No API keys. No cloud. Free forever.

Works With

• Claude Code (via MCP — auto-configured)
• VS Code (this extension)
• Any AI tool (via REST API)

Requirements

• Node.js >= 18
• npx indexa-mcp setup must be run in your project first
