Generate MongoDB Aggregations With Your Own AI Key
Describe what you want in natural language (any language) and get a MongoDB aggregation pipeline back - using your own AI key, with no token markup, and nothing runs until you say so.
Short answer: a bring-your-own-AI (BYO AI) MongoDB tool lets you type a request in natural language (any language) - like "average order value per month for 2025" - and returns a ready-to-review aggregation pipeline. You plug in your own OpenAI, Claude, or Google AI Studio key, pay the provider directly (no markup), and the generated pipeline is validated and shown as a draft - it never runs on its own. Byson is a mobile MongoDB client with built-in SSH tunneling; the AI aggregation generator is an optional bonus you can use with your own key. It works exactly this way on Android and iOS.
Disclosure: we make Byson. This explains how its BYO-AI aggregation feature works; the principles apply to any privacy-respecting AI query tool.
What "bring your own AI key" actually means
Most AI features bundle the model cost into a subscription and route your prompts through the vendor's servers. BYO AI flips that:
- You bring the key. Add your own key from Anthropic (Claude), an OpenAI-compatible endpoint, or Google AI Studio once in Settings.
- You pay the provider. Tokens are billed by your AI provider at their rate. Byson never resells or marks up AI credits.
- Your key stays yours. It's encrypted on-device, never logged, and never shown again after you save it.
Byson charges for the MongoDB workflow around the AI - schema analysis, prompt construction, validation, and history - not for the use of your key.
How a prompt becomes a pipeline
When you open the AI Copilot on a collection and type a request, here's what happens:
- Schema sampling. Byson samples the collection and builds a compact schema summary (field names and types).
- Safe prompt. The prompt sent to the provider contains that schema plus redacted or synthetic example values - never your raw documents.
- Generation. Your AI provider returns a pipeline, an explanation, and a list of assumptions.
- Strict parsing + validation. Byson parses the response as strict JSON and runs it through a safety validator that blocks dangerous stages like
$out,$merge, and$where, and warns on missing$limit. - Review, then run. The draft loads into the aggregation editor in AGGREGATE mode. It does not auto-run. You read it, edit if needed, and press Run yourself.
Why this is safe by design
| Risk with naive AI tools | How Byson handles it |
|---|---|
| AI sees sensitive data | Only a schema summary with redacted/synthetic examples leaves the device |
| AI writes a destructive stage | Pipeline validator blocks $out / $merge / $where before you can apply it |
| Query auto-runs and pulls huge data | Nothing runs until you press Run; previews are capped for mobile |
| Your API key leaks | Encrypted on-device, never logged, never displayed after save |
Cost and free quota
You pay your AI provider for tokens directly. Byson's own tiers:
- Free: 10 AI generations per day. The counter only increments on a successful, validated result - failed or unsafe responses don't count against you.
- Pro: unlimited AI generations, plus refine / explain / optimize and the full Schema Analyzer - $4.99/month, $39.99/year, or $79.99 lifetime.
The takeaway
BYO-AI aggregation gives you the speed of natural-language query generation without handing a vendor your data or your wallet. You keep the key, you keep the data on-device, and you keep the final say - the AI drafts, you review and run.

FAQ
What does bring-your-own-AI-key mean?
You supply your own API key from an AI provider (OpenAI, Claude, or Google AI Studio). You pay that provider directly for the tokens you use, and the app doesn't resell or mark up AI credits. In Byson the key is encrypted on-device and never logged.
Does the AI see my MongoDB data?
No. Byson sends a schema summary with redacted or synthetic example values - not your raw documents - to the AI provider. The model gets enough structure to write a pipeline without ever seeing real records.
Will an AI-generated aggregation run automatically?
No. Generated pipelines are validated for unsafe stages and shown as a draft with an explanation and assumptions. Byson loads it into the aggregation editor but never runs it - you review, edit, and press Run yourself.
