# The _Smartest_ Way  to Explore & Learn Open Source

## Wikis Are Dinosaurs. AI Learning Paths Are the Future

Open source is the backbone of the modern web. We decode complex codebases and forge learning paths that evolve as fast as the code does.

### Discover & Request

Search for any open source project. Can't find it? Request it and we'll add it to our library.

### Deep Research

Our engine performs a comprehensive analysis of the entire codebase to generate structured learning paths. This high-fidelity research can take up to 24 hours.

### Your Learning Style

Choose how you learn best: Socratic questioning, Feynman technique, or traditional book format.

## Let your agents query  _os.ninja_ via MCP

Give any coding agent access to curated open-source knowledge — learning paths, repo summaries, and structured docs — through a standard MCP server.

Connect via MCP

agent — mcp client

```bash
$xh mcp enable
```

✓ MCP server enabled

```bash
> search("rust async runtime internals")
↳ tokio — 142 learning units
↳ async-std — 89 learning units
> get_learning_path("tokio", mode="feynman")
↳ Returning 14 structured chapters…
```
