Getting Started with ArangoDB

Prerequisites

Docker and Docker Compose installed
Python 3.11+ (for mcp-arangodb-async)

Step 1: Install ArangoDB

Create a docker-compose.yml file:

services:
  arangodb:
    image: arangodb:3.11
    environment:
      ARANGO_ROOT_PASSWORD: ${ARANGO_ROOT_PASSWORD:-changeme}
    ports:
      - "8529:8529"
    volumes:
      - arangodb_data:/var/lib/arangodb3
      - arangodb_apps:/var/lib/arangodb3-apps
    healthcheck:
      test: arangosh --server.username root --server.password "$ARANGO_ROOT_PASSWORD" --javascript.execute-string "require('@arangodb').db._version()" > /dev/null 2>&1 || exit 1
      interval: 5s
      timeout: 2s
      retries: 30
    restart: unless-stopped

volumes:
  arangodb_data:
    driver: local
  arangodb_apps:
    driver: local

Create a .env file:

# ArangoDB root password
ARANGO_ROOT_PASSWORD=changeme

# MCP Server connection settings
ARANGO_URL=http://localhost:8529
ARANGO_DB=mcp_arangodb_test
ARANGO_USERNAME=mcp_arangodb_user
ARANGO_PASSWORD=mcp_arangodb_password

Start ArangoDB:

docker compose --env-file .env up -d

Step 2: Install mcp-arangodb-async

Install the MCP server package:

pip install mcp-arangodb-async

Alternative: Install with Conda/Mamba/Micromamba

# Create environment and install
conda create -n mcp-arango python=3.11
conda activate mcp-arango
pip install mcp-arangodb-async

# Or with mamba/micromamba:
# mamba create -n mcp-arango python=3.11
# mamba activate mcp-arango
# pip install mcp-arangodb-async

Alternative: Install with uv

# Create environment and install
uv venv .venv --python 3.11
uv pip install mcp-arangodb-async

Step 3: Create Database and User

Create the database and user for the MCP server:

maa db add mcp_arangodb_test \
  --url http://localhost:8529 \
  --with-user mcp_arangodb_user \
  --env-file .env

Expected output:

The following actions will be performed:
  [ADD] Database 'mcp_arangodb_test'
  [ADD] User 'mcp_arangodb_user' (active: true)
  [GRANT] Permission rw: mcp_arangodb_user → mcp_arangodb_test

Are you sure you want to proceed? [y/N]: y
db add:
[ADDED] Database 'mcp_arangodb_test'
[ADDED] User 'mcp_arangodb_user' (active: true)
[GRANTED] Permission rw: mcp_arangodb_user → mcp_arangodb_test

Verify the database connection:

# Set environment variables
export ARANGO_URL=http://localhost:8529
export ARANGO_DB=mcp_arangodb_test
export ARANGO_USERNAME=mcp_arangodb_user
export ARANGO_PASSWORD=mcp_arangodb_password

# Run health check
maa health

Expected output:

{"status": "healthy", "database_connected": true, "database_info": {"version": "3.11.x", "name": "mcp_arangodb_test"}}

Step 4: Configure MCP Host

Configure your MCP host to use the server. The configuration includes environment variables for database connection. The location of the configuration file depends on your MCP host. For Claude Desktop, the file is located at:

Windows: %APPDATA%\Claude\claude_desktop_config.json
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

Configuration:

{
  "mcpServers": {
    "arangodb": {
      "command": "python",
      "args": ["-m", "mcp_arangodb_async"],
      "env": {
        "ARANGO_URL": "http://localhost:8529",
        "ARANGO_DB": "mcp_arangodb_test",
        "ARANGO_USERNAME": "mcp_arangodb_user",
        "ARANGO_PASSWORD": "mcp_arangodb_password"
      }
    }
  }
}

Alternative: Configuration for Conda/Mamba/Micromamba

If you installed with conda/mamba/micromamba, use the run command:

{
  "mcpServers": {
    "arangodb": {
      "command": "conda",
      "args": ["run", "-n", "mcp-arango", "maa", "server"],
      "env": {
        "ARANGO_URL": "http://localhost:8529",
        "ARANGO_DB": "mcp_arangodb_test",
        "ARANGO_USERNAME": "mcp_arangodb_user",
        "ARANGO_PASSWORD": "mcp_arangodb_password"
      }
    }
  }
}

Replace "conda" with "mamba" or "micromamba" if using those tools.

Alternative: Configuration for uv

If you installed with uv, use uv run:

{
  "mcpServers": {
    "arangodb": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/project", "maa", "server"],
      "env": {
        "ARANGO_URL": "http://localhost:8529",
        "ARANGO_DB": "mcp_arangodb_test",
        "ARANGO_USERNAME": "mcp_arangodb_user",
        "ARANGO_PASSWORD": "mcp_arangodb_password"
      }
    }
  }
}

Replace /path/to/project with the directory containing your .venv folder.

Restart your MCP client after updating the configuration.

Test the connection:

Ask your MCP client: "List all collections in the ArangoDB database"

The assistant should successfully connect and list your collections.

Use Case Example: Codebase Graph Analysis

Model your codebase as a graph to analyze dependencies, find circular references, and understand architecture. Here is an excert from the longer codebase analysis example:

# 1. Create graph structure
Ask Claude: "Create a graph called 'codebase' with vertex collections 'modules' and  functions', and edge collection 'calls' connecting functions"

# 2. Import codebase data
Ask Claude: "Insert these modules into the 'modules' collection: [...]"

# 3. Analyze dependencies
Ask Claude: "Find all functions that depend on the 'auth' module using graph traversal"

# 4. Detect circular dependencies
Ask Claude: "Check for circular dependencies in the codebase graph"

# 5. Generate architecture diagram
Ask Claude: "Export the codebase graph structure as Markdown for visualization"
