Setup your Google API Credentials for the Gemini LLM\n2. Setup your OpenAI Credentials for the OpenAI embedding nodes.\n3. [MongoDB Atlas project and Cluster]({{ $env.WEBHOOK_URL }} Get a hold of the connection string and make sure to have your IP Access list enabled (for ease of testing try `0.0.0.0/0` access.\n4. Setup you MongoDB Credentials account with the correct connection string and database name.\n5. **Vector Search Tool** - uses Atlas Vector Search index you will create on your database for the `points_of_interest` collection:\n\n```\n// index name : \"vector_index\"\n// If you change an embedding provider make sure the numDimensions correspond to the model.\n{\n  \"fields\": [\n    {\n      \"type\": \"vector\",\n      \"path\": \"embedding\",\n      \"numDimensions\": 1536,\n      \"similarity\": \"cosine\"\n    }\n  ]\n}\n```\n\nOnce all of that is configured you will need to send the loading webhook with some data points (see example).\n\nThis should create vectorised data in  `points_of_interest` collection.\n\nOnce you have data points there try to ask the Agent questions about the data points and test the response. Eg. \"Where should I go for a romantic getaway?\"\n\n**Additional Resources**\n- [MongoDB Atlas Vector Search]({{ $env.WEBHOOK_URL }}\n- [n8n Atlas Vector Search docs]({{ $env.WEBHOOK_URL }}"
