Implementation Reference

src/server.py:467-480 (handler)

Python implementation of the mongodb_list_collections tool handler using pymongo to list collections in a specified database.

def mongodb_list_collections(database_name: str) -> str:
    """Gets list of collections"""
    client = MongoClient(MONGODB_URI)
    try:
        db = client[database_name]

        result = f'Collections in database "{database_name}":\n' + (
            "\n".join(collections) if collections else "No collections found"
        )
        return result
    except Exception as e:

    finally:
        client.close()

src/index.ts:696-721 (handler)

          type: "text",
          text: `Коллекции в базе данных "${databaseName}":\n${
            collectionNames.length > 0
              ? collectionNames.join("\n")
