Mcp Server Arangodb

1. Add the following configuration:

``json { "servers": { "arango-mcp": { "type": "stdio", "command": "npx", "args": ["-y", "arango-server"], "env": { "ARANGO_URL": "http://localhost:8529", "ARANGO_DB": "your_database_name", "ARANGO_USERNAME": "your_username", "ARANGO_PASSWORD": "your_password" } } } } ``

1. Start the MCP server:

• Open the Command Palette in VSCode (Ctrl+Shift+P or Cmd+Shift+P on Mac).
• Run the command MCP: Start Server and select arango-mcp from the list.

1. Verify the server:

• Open the Chat view in VSCode and switch to Agent mode.
• Use the Tools button to verify that the arango-server tools are available.

To use with Claude Desktop

Go to: Settings > Developer > Edit Config or

• MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%/Claude/claude_desktop_config.json

You can check out mcp documentation to set it up too.

To use with OpenCode

Add the following configuration to your OpenCode config file, such as opencode.json or opencode.jsonc:

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "arango": {
      "type": "local",
      "command": ["npx", "-y", "arango-server"],
      "enabled": true,
      "environment": {
        "ARANGO_URL": "your_database_url",
        "ARANGO_DB": "your_database_name",
        "ARANGO_USERNAME": "your_username",
        "ARANGO_PASSWORD": "your_password"
      }
    }
  }
}

After restarting OpenCode, ask it to use the arango MCP tools for ArangoDB tasks.

To use with Cline VSCode Extension

Go to: Cline Extension > MCP Servers > Edit Configuration or

• MacOS: ~/Library/Application Support/Code/User/globalStorage/cline.cline/config.json
• Windows: %APPDATA%/Code/User/globalStorage/cline.cline/config.json

Add the following configuration to the mcpServers section:

{
  "mcpServers": {
    "arango": {
      "command": "npx",
      "args": ["-y", "arango-server"],
      "env": {
        "ARANGO_URL": "your_database_url",
        "ARANGO_DB": "your_database_name",
        "ARANGO_USERNAME": "your_username",
        "ARANGO_PASSWORD": "your_password"
      }
    }
  }
}

You can also use the above configuration to get this server working with WARP

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
• ARANGO_BACKUP_ROOT - Optional root directory for arango_backup output. Defaults to ./backups.

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 "' 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",
  "limit": 100
}

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": "nightly_1", // Safe subdirectory name under ARANGO_BACKUP_ROOT. Absolute paths and slashes are rejected.
  "collection": "users", // Optional. If omitted, all collections are backed up.
  "docLimit": 1000 // Optional. Maximum documents per collection. Defaults to 1000 and is capped at 10000.
}

Set ARANGO_BACKUP_ROOT to choose where backups are stored. The server rejects path traversal, absolute paths, symlink escapes, and existing output files to mitigate arbitrary file write risks.

Create a new collection:

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

Drop a collection:

{
  "name": "products",
  "confirm": true
}

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

Contributions are welcome. Please read [CONTRIBUTING.md](./CONTRIBUTING.md) before opening a pull request.

1. Clone the repository
2. Install dependencies:

``bash npm run build ``

1. For development with auto-rebuild:

``bash 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.

Testing

npm test

The test suite includes regression coverage for the arango_backup path handling that prevents absolute paths, traversal, and symlink escapes.

To run the integration smoke test with a local Docker ArangoDB instance:

npm run test:integration

The integration test starts a temporary Docker ArangoDB instance, starts the MCP server over stdio, lists tools, verifies outputSchema, creates a temporary collection, inserts documents, queries with limit, verifies backup output stays under ARANGO_BACKUP_ROOT, rejects an absolute backup path, cleans up the collection, and stops the container.

The test container uses host port 18529 by default to avoid conflicting with a local ArangoDB on 8529. Override it with ARANGO_PORT if needed.
