akyn-ai

Turn any data source into an MCP server in 5 minutes.

Build knowledge bases that AI assistants like Claude and Cursor can query directly. No infrastructure needed.

What is this?

This SDK lets you create MCP (Model Context Protocol) servers from any data source. Your docs, PDFs, websites, or any text can become a queryable knowledge base that AI assistants can access directly.

Use cases:

• 📚 Make your documentation searchable by Cursor/Claude
• 🔍 Build RAG (Retrieval-Augmented Generation) pipelines
• 🤖 Create custom AI assistants with domain knowledge
• 📖 Index research papers, guides, or any text content

Quick Start

Install

npm install akyn-ai

Basic Usage

import { KnowledgeBase } from 'akyn-ai'

// Create a knowledge base
const kb = new KnowledgeBase({
  name: 'my-docs',
  description: 'My project documentation',
})

// Add your content
await kb.addDirectory('./docs')           // Add all docs from a folder
await kb.addFile('./README.md')           // Add a specific file
await kb.addURL('https://docs.example.com') // Scrape a URL
await kb.addText('Important info here')   // Add raw text

// Serve as MCP server
kb.serveStdio()  // For Cursor/Claude Desktop

Connect to Cursor

Add to your .cursor/mcp.json:

{
  "mcpServers": {
    "my-docs": {
      "command": "npx",
      "args": ["ts-node", "./my-kb.ts"],
      "env": {
        "OPENAI_API_KEY": "sk-..."
      }
    }
  }
}

Connect to Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "my-docs": {
      "command": "npx",
      "args": ["ts-node", "/path/to/my-kb.ts"],
      "env": {
        "OPENAI_API_KEY": "sk-..."
      }
    }
  }
}

Features

📁 Multi-Source Ingestion

// Files (PDF, DOCX, TXT, Markdown)
await kb.addFile('./guide.pdf')
await kb.addFile('./manual.docx')

// Directories (recursive)
await kb.addDirectory('./docs', {
  recursive: true,
  extensions: ['.md', '.txt', '.pdf'],
})

// URLs
await kb.addURL('https://docs.example.com')
await kb.addURLs([
  'https://example.com/page1',
  'https://example.com/page2',
])

// Raw text
await kb.addText('Custom content here', 'My Notes')

🔍 Smart Chunking

Text is automatically split into optimal chunks for embedding:

const kb = new KnowledgeBase({
  name: 'my-kb',
  chunking: {
    maxSize: 1000,    // Max characters per chunk
    overlap: 200,     // Overlap between chunks for context
  },
})

🧠 Flexible Embeddings

Uses OpenAI by default, but you can bring your own:

import { KnowledgeBase, type EmbeddingsProvider } from 'akyn-ai'

// Use OpenAI (default)
const kb = new KnowledgeBase({ name: 'my-kb' })

// Or customize OpenAI settings
import { OpenAIEmbeddings } from 'akyn-ai'

const kb = new KnowledgeBase({
  name: 'my-kb',
  embeddings: new OpenAIEmbeddings({
    model: 'text-embedding-3-large',  // Better quality
    apiKey: 'sk-...',
  }),
})

// Or bring your own provider
class MyEmbeddings implements EmbeddingsProvider {
  readonly dimensions = 384
  
  async embed(text: string) {
    // Your embedding logic here
    return { embedding: [...], tokenCount: 100 }
  }
  
  async embedBatch(texts: string[]) {
    return Promise.all(texts.map(t => this.embed(t)))
  }
}
