Installation

Prerequisites

• Python 3.11+
• Docker Desktop (for ArangoDB)

Quick Install

# Install from PyPI
pip install mcp-arangodb-async

# Start ArangoDB
docker run -d \
  --name arangodb \
  -p 8529:8529 \
  -e ARANGO_ROOT_PASSWORD=changeme \
  arangodb:3.11

# Verify installation
python -m mcp_arangodb_async --health

Expected output:

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

Quick Start

stdio Transport (Desktop Clients)

1. Configure Claude Desktop

Edit %APPDATA%\Claude\claude_desktop_config.json (Windows) or ~/.config/Claude/claude_desktop_config.json (macOS/Linux):

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

2. Restart Claude Desktop

3. Test the connection:

Ask Claude: "List all collections in the ArangoDB database"

---

HTTP Transport (Web/Containerized)

1. Start HTTP server:

python -m mcp_arangodb_async --transport http --host 0.0.0.0 --port 8000

2. Test health endpoint:

curl http://localhost:8000/health

3. Connect from web client:

import { MCPClient } from '@modelcontextprotocol/sdk';

const client = new MCPClient({
  transport: 'http',
  url: 'http://localhost:8000/mcp'
});

await client.connect();
const tools = await client.listTools();

Use Case Example: Codebase Graph Analysis

Model your codebase as a graph to analyze dependencies, find circular references, and understand architecture:

# 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"

Troubleshooting

Common Issues

Database connection fails:

# Check ArangoDB is running
docker ps | grep arangodb

# Test connection
curl http://localhost:8529/_api/version

# Check credentials
python -m mcp_arangodb_async --health

Server won't start in Claude Desktop:

# Verify Python installation
python --version  # Must be 3.11+

# Test module directly
python -m mcp_arangodb_async --health

# Check Claude Desktop logs
# Windows: %APPDATA%\Claude\logs\
# macOS: ~/Library/Logs/Claude/

Tool execution errors:

• Verify ArangoDB is healthy: docker compose ps
• Check environment variables are set correctly
• Review server logs for detailed error messages
