✓Use projection to return only needed fields

✓Implement proper input validation for filters

✓Use aggregation pipelines for complex queries

Frequently asked questions

Can AI agents use MongoDB?+

Yes. Through the Atlas Data API, agents perform CRUD operations and aggregations without managing database drivers. This works in serverless environments.

MongoDB vs PostgreSQL for AI agents?+

MongoDB flexible schemas are easier for agents to work with — no migrations needed. PostgreSQL is better for relational data and complex joins. Choose based on data structure.

How do agents handle MongoDB queries?+

Through the findDocuments action with JSON filter objects. Agents can query by any field, use comparison operators, and sort results.
