GrowthBook + Memtro

How is the pricing experiment doing, and is new-checkout on in production?

GrowthBook holds your feature flags and the experiments that test them. Memtro reads flags with their environments, rules and change history, experiments with status, phases and results, and projects, metrics and segments, never metric or segment SQL. When asked and once an administrator has granted the action by name, it can turn flags on or off, create, edit, revert, archive or delete flags, create, start and stop experiments, comment on them, and refresh results, which runs queries on your data warehouse. Flag changes and started experiments reach live users at once. Deleting a flag is permanent.

In Memtro

What you can do with GrowthBook in Memtro

Ask in plain English from chat, your editor, a scheduled job or your own agent. The model picks the right GrowthBook tool, reads what it needs, and answers with the source cited.

What it does

  1. 01Lists feature flags with value type, default value, owner, tags, the environments each is enabled in and how many rules it has, and reads one flag's rules.
  2. 02Reads the change history of flags, with who created and published each revision and when.
  3. 03Lists experiments with status, hypothesis, variations, the current phase and the recorded winner, and reads the latest results with percent change, confidence interval and the sample-ratio check.
  4. 04When asked and granted, turns a flag on or off in named environments, creates, edits, reverts or archives flags, and publishes draft revisions. End users get the change at their next SDK refresh. Deleting a flag is permanent.
  5. 05When asked and granted, creates or edits draft experiments, starts one so live users get its variations, stops it and records the result, and archives it.
  6. 06When asked and granted, comments on an experiment's discussion, where watchers may be notified, and runs a fresh results analysis, which queries your data warehouse at its compute cost.

Acts when asked

When you ask it to

These tools change something in GrowthBook. The model is told to use them only when you ask for exactly that, and an administrator grants each one by name to the teams that may use it; a personal connection acts only after its owner allows it.

  1. 01Add a comment to an experiment's discussion
  2. 02Turn a feature flag on or off in named environments, publishing at once
  3. 03Create a feature flag, off in every environment
  4. 04Edit a flag's description, owner, default value, tags or project
  5. 05Archive or unarchive a feature flag
  6. 06Revert a flag to an earlier revision, or publish a draft revision
  7. 07Delete a feature flag and all its revisions permanently
  8. 08Create a draft experiment, or edit its name, hypothesis, description, owner, tags or metrics
  9. 09Start an experiment, or stop it and record the result
  10. 10Archive or unarchive an experiment
  11. 11Run a fresh results analysis for an experiment (queries the data warehouse)

Events

When it happens

Turn events on in the connection's Events tab on the Connections page, then add the address it shows as a webhook in GrowthBook, choosing the same kinds; the tab shows GrowthBook's own steps. Each event can start a job, with the event as its input. GrowthBook signs every delivery, and one whose signature does not check out is refused before it is read.

In practice

Ask it like you would a colleague

Once GrowthBook is connected, these are the kinds of things people ask. Plain questions, no syntax. If the answer lives partly in another system you have connected, Memtro looks there too.

GrowthBook logoGrowthBook + Memtro
  • Is new-checkout on in production?

  • How is the pricing experiment doing?

  • Who changed the checkout flag last week?

  • Which experiments are running in the web project?

  • Stop the pricing experiment and record variation B as the winner.

01

Reading an experiment

Maya Okafor, growth product manager at Acme Ltd, asked how the pricing experiment was doing. Memtro read the latest analysed results. It reported users per variation, each variation's percent change against control with its confidence interval, and the sample-ratio check.

02

Calling the result

After two more weeks of data, Maya asked Memtro to stop the pricing experiment and record it as won. Memtro stopped the experiment with that result, so live users stopped getting the variations, and posted her approved summary to its discussion, where watchers may be notified.

Teams

Where it fits

The teams that lean on GrowthBook most, a question each of them asks, and what they connect beside it.

Better together

Works with

A record in GrowthBook is rarely the whole story. Connect the systems that hold the rest and Memtro checks them together, then remembers what it learned so the next question starts further along.

Also in Engineering and operations

Using something else for the same job, or both? Each connector has its own tools; connect as many as you like.

Setup

How to connect

Connect withSecret Key or personal access token
  1. 1

    In GrowthBook, open Settings → API Keys and create a Secret Key with the narrowest role that covers what you will ask Memtro to do, read-only if you only want answers. It starts secret_.

  2. 2

    A personal access token from the user menu → Personal Access Tokens also works, and acts as you, with your access.

  3. 3

    In Memtro, open Connections → GrowthBook and paste it into Secret Key or personal access token. Fill API host and Port only if you self-host, and Requested by only for a Secret Key in User mode.

  4. 4

    Ask: how is the pricing experiment doing?

Also works from

Chat in the dashboard, the OpenAI-compatible API, scheduled jobs, and any MCP client: Claude Code, OpenCode, Cursor, Claude Desktop. The GrowthBook tools are the same everywhere.

FAQ

Questions

Can Memtro change anything in GrowthBook?+

Only when you ask, and only what it has been granted: add a comment to an experiment's discussion; turn a feature flag on or off in named environments, publishing at once; create a feature flag, off in every environment; edit a flag's description, owner, default value, tags or project; archive or unarchive a feature flag; revert a flag to an earlier revision, or publish a draft revision; delete a feature flag and all its revisions permanently; create a draft experiment, or edit its name, hypothesis, description, owner, tags or metrics; start an experiment, or stop it and record the result; archive or unarchive an experiment; run a fresh results analysis for an experiment (queries the data warehouse). Every other tool reads, searches or lists. The Connections page labels the tools that act, an administrator grants each one by name to the teams that may use it, and a personal connection acts only after its owner allows it.

Who can use a GrowthBook connection?+

A personal connection serves only your own requests. A shared connection serves the organisation: everyone, or only the teams an admin chooses. Admins can always add shared connections; other members need the permission.

Does Memtro store my GrowthBook data?+

Credentials are encrypted at rest. Tool results are cached briefly so agent loops do not repeat identical calls, and the facts the model extracts are saved to your organisation's memory with provenance (system, record and link) so they can be checked and superseded.

How do I connect GrowthBook?+

Secret Key or personal access token. In GrowthBook, open Settings → API Keys and create a Secret Key with the narrowest role that covers what you will ask Memtro to do, read-only if you only want answers. It starts secret_.

Can GrowthBook start a job?+

Yes. Turn events on in the connection's Events tab on the Connections page, then add the address it shows as a webhook in GrowthBook, choosing the same kinds; the tab shows GrowthBook's own steps. A job set to start "When an event arrives" then runs once for each matching event, with the event as its input. The run treats the event as outside data, never as instructions, and anything the run remembers is kept as unverified.
