About ArangoDB MCP Server

What is ArangoDB MCP Server: Zero Downtime & Enterprise Failover?

ArangoDB MCP Server is a Model Context Protocol (MCP) implementation for ArangoDB, enabling seamless database operations with zero downtime and enterprise-grade failover capabilities. It provides a standardized interface for executing read/write queries, managing databases and collections, and maintaining high availability through advanced resource management and fault tolerance mechanisms.

How to Use ArangoDB MCP Server: Zero Downtime & Enterprise Failover?

To deploy the server, configure the `claude_desktop_config.json` with connection details to your ArangoDB instance, including hostname, port, and credentials. Initialize the environment via npm commands: install dependencies, set up development configurations, and start the server. Use dedicated tools like `readQuery` for read-only operations and `readWriteQuery` for transactions, while `listDatabases` and `listCollections` help manage database structures dynamically.

ArangoDB MCP Server Features

Key Features of ArangoDB MCP Server: Zero Downtime & Enterprise Failover?

  • Zero Downtime Operations: Maintains service availability during maintenance or upgrades through real-time failover mechanisms.
  • Enterprise Failover: Ensures automatic failover to standby nodes with minimal data loss, enhancing system reliability.
  • Resource Management: Supports database and collection listing, document retrieval via templates, and client pooling for optimized performance.
  • Security & Compliance: Enforces authentication via username/password parameters and secure configuration handling.
  • Development Tools: Includes a live dev server and resource inspector for streamlined debugging and integration.

Use Cases of ArangoDB MCP Server: Zero Downtime & Enterprise Failover?

Deploy this server in scenarios requiring:

  • High-availability database environments with automatic recovery from node failures.
  • Real-time data processing with guaranteed uptime for critical operations.
  • Multi-tenant architectures where multiple databases must be dynamically accessed and managed.
  • Compliance-driven systems needing explicit control over query execution and resource allocation.

ArangoDB MCP Server FAQ

FAQ from ArangoDB MCP Server: Zero Downtime & Enterprise Failover?

  • How does failover ensure zero downtime? The server monitors node health and redirects traffic to healthy instances without interrupting active sessions.
  • What authentication methods are supported? Username/password parameters are required during server initialization for secure access.
  • Can I execute complex transactions? Yes, the `readWriteQuery` tool supports full AQL queries, including multi-statement transactions.
  • How is multi-database access handled? The server connects to all databases on an ArangoDB instance, with context switching via `databaseName` parameters.
  • When will this be available on npm? Ongoing development includes packaging for npm to simplify deployment via `npx`.

Query Tools

  • readQuery
    • Execute read-only query on the database
    • Input:
      • databaseName (string): The database to query
      • aql (string): The read-only AQL query to execute
    • Returns: Query results as array of objects
  • readWriteQuery
    • Execute query on the database
    • Input:
      • databaseName (string): The database to query
      • aql (string): The AQL query to execute
    • Returns: Query results as array of objects
  • listDatabases
    • List all the databases on the ArangoDB server
    • Returns: Array of the databases names
  • listCollections
    • List all the collections in an ArangoDB database
    • Input:
      • databaseName (string): The name of the database
    • Returns: Array of objects { "name": "<collectionName>" }

Usage

To connect to an arangodb instance running on localhost:2434, to the database "account", add the following to your claude_desktop_config.json, assuming the path to this project is /home/yourcoolname/arango-mcp-server:

{
  "mcpServers": {
    "arangodb-account": {
      "command": "npx",
      "args": [
        "-y",
        "arango-mcp-server",
        "http://localhost:8529",
        "root",
        "root"
      ]
    }
  }
}

Development

Clone the repository. Install everything. Setup the dev environment. Run the watcher. Edit index.ts.

$ npm install
$ npm run dev:setup
$ npm run dev

Go to http://localhost:5173/ to see the inspector.

Todo

  • Properly study the spec to see if the current implementation of resources actually make sense (I don't think it does)
    • The resource templates make sense
  • Change all the "arango" to "arangodb" (repo name included...)
  • Add back the arangodb password
  • Proper README
    • Tools/resource/etc following the format of the official anthropic stuff
  • Figure out notifications
  • Health checks
  • More tools?
  • Access all the databases running on an arangodb instance
  • Release on npm somehow so it can be used with npx
  • resources/subscribe and notifications/resources/list_changed and resources/unsubscribe
  • Properly document tools in the readme
  • Like on the SQLite MCP client
    • write_query tool separated from read_query -> actually is readWriteQuery
    • list_collections (see list_tables)
  • Client pool ie one client per database
  • Dev environment
  • resources/read with a template to read any document by database name, collection, id.
  • Add username and passwords as parameters of the command
