ADoor vs MongoDB Atlas
MongoDB Atlas is a managed document database for applications, from a free cluster to dedicated ones. ADoor, your data account, keeps the records a team or a company shares with apps and assistants like ChatGPT, with standard SQL underneath and access per field and entry.
Where ADoor stands out
Access per field and entry
Atlas admins can enforce read-only for AI clients and set roles per MCP configuration. ADoor sets access per list or field, or to the entries that match a value you choose, with adding, editing and deleting separate.
Approvals
In ADoor, agents ask for more access and you approve or deny, and new devices sign in only after you approve them.
Standard SQL
ADoor runs on Postgres, so lists can be queried in standard SQL through MCP and the API.
The products
MongoDB Atlas
MongoDB Atlas runs managed MongoDB clusters, with Free, Flex and Dedicated tiers.
- Assistants
- A managed MCP server in Atlas, or a local one you run yourself
- Access
- Org-level opt-in, read-only enforcement, per-configuration roles and IP access lists
- Plans
- Free with 512 MB. Flex from $0.011 an hour, up to $30 a month.
ADoor
ADoor is your data account. You keep lists and tables in a workspace you own, personal or team: a reading list, an incident log, a list of customers. Describe what you want to keep track of and it's set up for you, with real Postgres underneath. Every person, app, assistant, device and job gets its own access.
- Assistants
- ChatGPT, Claude, Grok and Cursor connect through MCP with a sign-in.
- Apps and scripts
- An HTTP API with keys, running the same actions assistants use
- Access
- Per space, list or field, or just the entries where a field equals a value you choose. Reading, adding, editing and deleting entries, and changing a list's fields, are separate permissions. An assistant never gets more than the person who connected it.
- Approvals
- Agents ask for more access and you approve or deny. A new device signs in only after you approve it and choose its access.
- CI jobs
- GitHub Actions signs in with short-lived access, 15 minutes by default and up to 30 days, with no stored secret.
- Revoking
- Takes effect on the next request. What was already saved stays.
- History
- A history of changes, with who made each one and the before and after
- Underneath
- Standard Postgres
- Plans
- Free for 3 tables and 100 rows. Pro is $10 a month per workspace, with 1 GB of storage.
