A little help with
the next query.

Ask the query assistant for MQL, then review and edit its response. Or connect an MCP-compatible agent to the databases you explicitly allow.

AI is optional. External providers receive the context needed for your request; check your provider and connection settings before using sensitive data.

Is MQLens free?

Yes. MQLens is free and open source under the Apache-2.0 license. You can download it without an account. Optional external AI providers may charge for API usage.

Can I connect to MongoDB Atlas or a local database?

MQLens accepts MongoDB connection strings for local and remote deployments. Your network access and database permissions still apply. SSH tunnels, TLS, and several authentication methods are available.

Does MQLens collect telemetry?

The desktop app does not collect telemetry. Connection credentials are encrypted locally. Requests to your MongoDB deployment and optional AI providers are part of the workflows you choose to use.

What safeguards are available for production?

You can mark connections read-only or require confirmation for destructive operations. These controls help reduce accidental changes; use appropriate MongoDB permissions and backups as well.

Do I need mongosh or an AI key?

Neither is needed to browse or query through the GUI. The embedded shell requires a mongosh installation. The optional query assistant needs a configured provider or supported local agent CLI.
