Overview

Stacklit is a tool that transforms large codebases into compact, structured indexes (~250 tokens) that replace 50,000+ tokens of exploration. It parses code with tree-sitter for 11+ languages to extract module structure, dependencies, exports, and type definitions. The generated stacklit.json file provides AI agents with immediate codebase context without requiring file-by-file scanning. It includes MCP server functionality exposing 7 tools for retrieving overview, modules, dependencies, and hints.

Try asking AI

After installing, here are 5 things you can ask your AI assistant:

you:Provide AI coding assistants with instant codebase context without overwhelming context windows
you:Automatically configure Claude Code, Cursor, and Aider with codebase indexes
you:Generate visual dependency maps and navigation aids for complex projects
you:Does Stacklit read my code?
you:What if my language isn't supported?

When to choose this

Choose Stacklit when working with AI coding assistants on large codebases where context window efficiency is critical and you need structured code navigation without overwhelming the agent with raw code.

When NOT to choose this

Don't choose Stacklit if you're working with very small codebases where the overhead of maintaining an index outweighs the benefits, or if you need real-time code analysis without any pre-processing.

Installation

Install Stacklit

npm install -g stacklit              # install globally
stacklit init                        # scan codebase
stacklit serve                       # start MCP server

Configure Claude Desktop with MCP:

{
  "mcpServers": {
    "stacklit": {
      "command": "stacklit",
      "args": ["serve"]
    }
  }
}

Configure Claude Code:

stacklit setup claude                # updates CLAUDE.md + .mcp.json

FAQ

Does Stacklit read my code?
Yes, locally only. It parses source files with tree-sitter to extract structure (imports, exports, types). No code is sent anywhere unless you use the optional --summary flag.
What if my language isn't supported?
Stacklit falls back to basic support (line count + language detection) for any language not in the tree-sitter list. The module map, dependency graph, and git activity still work.
