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": "node",
      "args": [
        "/home/yourcoolname/arango-mcp-server/dist/index.js",
        "https://localhost:2434",
        "username",
        "password"
      ]

Todo

• [ ] Properly study the spec to see if the current implementation of resources actually make sense (I don't think it does)
  • [x] 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
• [x] Properly document tools in the readme
• [x] Like on the SQLite MCP client
  • [x] write_query tool separated from read_query -> actually is readWriteQuery
  • [x] list_collections (see list_tables)
• [x] Client pool ie one client per database
• [x] Dev environment
• [x] resources/read with a template to read any document by database name, collection, id.
• [x] Add username and passwords as parameters of the command
