BerryRAG MCP Server

Local vector DB with Playwright MCP integration to scrape, embed, and query Claude-facing content.

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "berrydev-ai-berry-rag": {
      "url": "https://mcp.berrydev.ai/berry-rag"
    }
  }
}

You set up BerryRAG as an MCP-enabled local knowledge base that combines a vector database with Playwright-based web scraping. This lets Claude access up-to-date, scraped content processed into embeddings, so you can search, retrieve context, and get precise answers from your own data.

How to use

Configure Claude Desktop to connect to the two MCP servers used by BerryRAG. This enables you to drive Playwright scraping through Claude and to operate the local vector database directly from Claude’s workflow.

"mcpServers": {
  "playwright": {
    "command": "npx",
    "args": ["@playwright/mcp@latest"]
  },
  "berry-rag": {
    "command": "node",
    "args": ["mcp_servers/vector_db_server.js"],
    "cwd": "/Users/eberry/BerryDev/berry-rag"
  }
}

Typical workflow with Claude and BerryRAG

1) Scrape target content via Playwright MCP through Claude using your configured servers. 2) Process scraped content into the local vector database. 3) Query and search your knowledge base to retrieve context and answers.
