We have so many exciting projects we’re working on, we decided to do something a little different for this next release. June will be our official Launch Month! Every week we’ll announce major new features and changes to GrowthBook that you can try out early, before the final release at the end of the month.
Let’s kick things off with the Week 1 launches:
GrowthBook MCP Server
We launched the first ever MCP server for feature flagging and experimentation! MCP (Model Context Protocol) allows AI tools to communicate and do actions directly with services like GrowthBook. Now you can use AI to create feature flags, check experiment results, clean up stale code, and more, directly within your IDE. Read our announcement blog post for more info and a demo.
Even Safer Rollouts
We made three big changes to Safe Rollouts to make them even safer:
- Traffic now gradually ramps up from 10% to 100%
- Results are checked more frequently at the start of a Safe Rollout (and less frequently the longer it’s running)
- There’s a new setting to automatically roll back if any guardrails are failing or the data looks unhealthy
When combined, these changes help make your rollouts even safer by minimizing the user impact when things go wrong. As always, you can learn more about this in our docs.
Custom Decision Criteria
You can now customize the logic that powers our Experiment Decision Framework on a per-experiment basis.
- Clear Signals (the default) - Ship only with clear goal metric successes and no guardrail failures.
- Do No Harm - Ship so long as no guardrails and no goal metrics are failing. Useful if the costs of shipping are very low.
- Custom - Define your own fully custom decision criteria logic using our intuitive UI.
Check out our docs for more information.
Search Filters
We’ve revamped the search experience within GrowthBook to make it easier to find feature flags and metrics. Easily filter by project, owner, tag, type, and more. The best part is that all of your filters are encoded in the URL, so once you find a view you like you can easily get back to it or share it with your team. We’ll be rolling this out to other parts of the app soon.
