Everything your data team needs to govern document databases – in one place

3T Lens lets you give the right people (and AI agents) access to the data they need with PII controls, access policies, and a full built-in audit trail.

One workspace your whole data team will actually use

AI tools have no idea what your access policies say, or which fields contain personal data. That’s a compliance problem hiding inside workflows you’re already running. 3T Lens puts a governance layer across every connection (human or AI), so you always know who accessed what, when, and why. 

Centralized connection control

Access is set up and managed automatically through Access Manager, so there’s no need to share login details or worry about hidden or unauthorised access.

Compliance at a 
glance

Check the health of each environment in one click, based on a set of configurable governance rules.

AI-ready governance

The same access rules apply to both AI tools and human users, so everyone only sees and uses the data they’re allowed to.

Governed, auditable database operations

AI can generate queries quickly, but it still needs guardrails. 3T Lens helps teams stay in control while keeping a clear record of every action for auditing and review.

Spot breaking changes early

Versioned field history across your collections catches breaking changes before they reach production.

Compare data changes clearly

With exact document-level diffs you can see exactly what’s been added, removed, or changed between two datasets, so you can understand differences and keep systems in sync.

Improve query performance more easily

Understand how queries are running and get clear suggestions to improve performance, including where indexes may be needed.

Built-in governance, PII risk, and access control

3T Lens helps you stay secure and compliant from the start. You set your rules once, and they apply to everyone and everything accessing your data, including engineers, analysts, and AI tools. It also tracks access activity so you have a clear audit trail when you need it.

Ready-made policy templates

Start quickly with pre-built governance rules for ACID, Schema, Index, Security, Naming, and Operational categories, configurable per environment.

Automated PII classification

Data is automatically scanned and grouped by sensitivity, helping you identify what needs protection. Every scan is recorded so you can show what was checked and when.

Alerts when something goes wrong

If there’s a policy issue, it’s flagged with a clear severity level, and you can be notified through Slack, email, or webhooks.

Bespoke scripts

Expensive to build, brittle, invisible to the organisation, impossible to audit.

3T Lens

Replace custom extraction and sync scripts with governed, scheduled, auditable workflows your whole team can access.

Works with your stack, not against it

Control access for people and AI working with your MongoDB data. Protect sensitive data as it moves through your system and enforces access rules based on who or what is making the request.

Works in your browser

3T Lens runs entirely in the browser, so there’s nothing to install, update, or manage through IT support. 

Centralised access control

Database connections are set up in one place and automatically shared with the right users. There are no shared passwords, hidden connections, or unmanaged access routes.

Works with your existing workflows

You can connect Studio 3T to your existing tools and pipelines using secure APIs, so it fits into your CI/CD and automation processes.

Built for AI tools

3T Lens connects AI agents to your database through MCP, with 59 tools across 10 categories. This allows LLMs to safely orchestrate database operations as part of larger governed workflows.

Works across desktop and web

Work done in the browser is also available in the desktop IDE, so teams can move between tools without losing context or redoing work.
