flyto-indexer

Code intelligence MCP server for AI-assisted development. Know what breaks before you change it.

What It Does

flyto-indexer indexes your codebase and provides AI agents with:

• Impact analysis — determine blast radius before changing code
• Cross-project tracking — find all references across multiple repos
• Semantic search — ranked symbol search across indexed projects
• Code quality analysis — security scans, dead code, complexity scoring
• Change assessment — parse git diffs and identify affected symbols

Key Stats

• Zero external dependencies
• 30 MCP tools
• 6 language parsers (Python, TypeScript, Vue, Go, Rust, Java)
• PyPI package: flyto-indexer

Quick Start

Installation

pip install flyto-indexer

Index a Project

flyto-index scan /path/to/project

Use as MCP Server

Add to your MCP client configuration:

{
  "mcpServers": {
    "flyto-indexer": {
      "command": "python3",
      "args": ["-m", "flyto_indexer.mcp_server"]
    }
  }
}

Architecture

Source Files
  → Language Scanners (AST/regex parsing)
    → Symbol Index (functions, classes, components, APIs)
      → Dependency Graph (imports, calls, extends)
        → Reverse Index (symbol → callers)
          → MCP Tools (30 tools for AI agents)

Key Design Decisions

• Reverse index — Pre-computed during indexing for instant impact analysis
• Incremental indexing — Content hashing, only re-scans modified files
• Auto-reindex — Checks freshness every 5 minutes, reindexes on change
• Zero deps — Pure Python, no external packages required
