Environment Variables

The server requires the following environment variables:

• ARANGO_URL - ArangoDB server URL (note: 8529 is the default port for ArangoDB for local development)
• ARANGO_DB - Database name
• ARANGO_USERNAME - Database user
• ARANGO_PASSWORD - Database password

Usage

You can pretty much provide any meaningful prompt and Claude will try to execute the appropriate function.

Some example propmts:

• "List all collections in the database"
• "Query all users"
• "Insert a new document with name 'John Doe' and email "john@example.com' to the 'users' collection"
• "Update the document with key '123456' or name 'Jane Doe' to change the age to 48"
• "Create a new collection named 'products'"

Usage with Claude App

Uasge with Cline VSCode extension

Query all users:

{
  "query": "FOR user IN users RETURN user"
}

Insert a new document:

{
  "collection": "users",
  "document": {
    "name": "John Doe",
    "email": "john@example.com"
  }
}

Update a document:

{
  "collection": "users",
  "key": "123456",
  "update": {
    "name": "Jane Doe"
  }
}

Remove a document:

{
  "collection": "users",
  "key": "123456"
}

List all collections:

{
} // No parameters required

Backup database collections:

{
  "outputDir": "./backup" // Specify an absolute output directory path for the backup files (optional)
  "collection": "users" // Specify a collection name to backup (optional) If no collection name is provided, all collections will be backed up
  "docLimit": 1000 // Specify the maximum number of documents to backup per collection (optional), if not provided, all documents will be backed up (not having a limit might cause timeout for large collections)
}

Create a new collection:

{
  "name": "products",
  "type": "document", // "document" or "edge" (optional, defaults to "document")
  "waitForSync": false // Optional, defaults to false
}

Note: The server is database-structure agnostic and can work with any collection names or structures as long as they follow ArangoDB's document and edge collection models.

Disclaimer

For Development Use Only

This tool is designed for local development environments only. While technically it could connect to a production database, this would create significant security risks and is explicitly discouraged. We use it exclusively with our development databases to maintain separation of concerns and protect production data.

Development

1. Clone the repository

2. Install dependencies:

   npm run build
   

3. For development with auto-rebuild:

   npm run watch
   

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. recommended debugging can be done by using MCP Inspector for development:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.
