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"
      ]
    }
  }
}

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
