Researched, not yet run live. Built from the provider’s official pages (linked below). A person hasn’t walked this flow end to end yet, so check each step against the source.
Who owns what
An Atlas user belongs to organizations; projects inside an organization hold clusters, database users and the IP access list.
- Atlas user personal owned by the person
- Organization organisation · under Atlas user
- Project project · under Organization
Steps
Steps marked “human step” are ones only you can do: verapli never signs in, submits, pays or accepts terms for you.
Create or sign in to an Atlas account
The person registers at MongoDB Atlas (or signs in). verapli never creates the account.
Where: https://www.mongodb.com/cloud/atlas/register
Create a free cluster
Create a Free cluster in the Atlas UI, choosing cloud provider and region, or run atlas setup --clusterName <name> --provider AWS --region <region> --username <user> --password <password>. Only one Free cluster per project.
Create a database user
Create a database user and password for the app (atlas setup does this with --username and --password).
Add an IP access list entry
Add the app's IP address or CIDR range to the project IP access list; Atlas refuses connections from anywhere else. Temporary entries can expire within 7 days.
If something goes wrong (1)
- Connection suddenly times out from a home or office network.: The public IP has probably changed; check it still matches an access list entry. [3]
Copy the connection string
On the Clusters page click Connect, Drivers, pick the driver and version, copy the connection string and replace <db_password> with the user's password. verapli stores it as MONGODB_URI.

Terms and gotchas
Plain-English summary, not legal advice. Each card links its source.
Free clusters are limited to 0.5 GB, 100 operations per second (excess is throttled) and 500 connections. [2]
What you end up with
| Env var | Secret | Format | What it is |
|---|---|---|---|
MONGODB_URI | secret | Driver connection string including the database user's credentials. The Atlas docs do not fix an env var name; MONGODB_URI is chosen by verapli. |
Pricing
- Free tier: One Free cluster per project, 0.5 GB storage, 100 ops/s, 500 connections.
