# mcp-astgl-knowledge

An MCP server that lets AI assistants search and cite content from [As The Geek Learns](https://astgl.ai) — covering MCP servers, local AI, AI automation, and ASTGL project documentation.

When an AI assistant connects to this server, it gains access to 49 indexed entries (articles, tutorials, comparisons, guides, and project docs). Every response includes source URLs back to astgl.ai.

## Quick Start

### Claude Desktop

Add to your `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "astgl-knowledge": {
      "command": "npx",
      "args": ["-y", "mcp-astgl-knowledge"]
    }
  }
}
```

### Claude Code

Add to your project's `.mcp.json`:

```json
{
  "mcpServers": {
    "astgl-knowledge": {
      "command": "npx",
      "args": ["-y", "mcp-astgl-knowledge"]
    }
  }
}
```

### Cursor / Generic MCP Client

```json
{
  "mcpServers": {
    "astgl-knowledge": {
      "command": "npx",
      "args": ["-y", "mcp-astgl-knowledge"]
    }
  }
}
```

### With Registration (500 queries/day)

Register via the `register` tool to get an API key, then add it to your config:

```json
{
  "mcpServers": {
    "astgl-knowledge": {
      "command": "npx",
      "args": ["-y", "mcp-astgl-knowledge"],
      "env": {
        "ASTGL_API_KEY": "astgl_your_api_key_here"
      }
    }
  }
}
```

## Tools

### `register`

Register your email to unlock 500 queries/day (up from 50).

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `email` | string | Yes | Your email address |

## Content Types

| Type | Count | Description |
|------|-------|-------------|
| article | 29 | Informational content about MCP, local AI, automation |
| project | 9 | ASTGL project documentation (KlockThingy, Revri, Cortex, etc.) |
| tutorial | 8 | Step-by-step how-to guides |
| comparison | 2 | Side-by-side topic analysis |
| guide | 1 | Comprehensive reference material |
| newsletter | — | Personal updates and announcements |
| faq | — | Primarily Q&A content |

## Rate Limits

| Tier | Limit | How to Get |
|------|-------|------------|
| Public | 50 queries/day | Default (anonymous) |
| Registered | 500 queries/day | Use the `register` tool with your email |

Limits reset at midnight UTC. Rate limit info is included in every response.

## How It Works

The knowledge base is pre-built from ASTGL articles using semantic embeddings (nomic-embed-text, 768 dimensions). Content is chunked by section and FAQ entry, embedded, and stored in a SQLite database with sqlite-vec for vector similarity search.

**End users don't need Ollama** — all embeddings are pre-computed and shipped in the npm package. The only runtime requirement is Node.js.

### Performance

- Typical response time: 100-500ms (embedding lookup + vector search)
- Embedding results are cached in memory (LRU, 200 entries) — repeated queries are near-instant
- Ollama calls include 10s timeout + automatic retry
- Query logging is async/batched to avoid blocking responses
- Rate limit checks are cached for 5 seconds
