## How to connect an Atlas Cloud API key to Phersa

1. ### Step 1: Get an Atlas Cloud API key

    Sign in at atlascloud.ai, open API keys in the console and create a key. It starts with apikey-. Atlas Cloud takes generation costs from your Atlas Cloud balance, so add funds to your account too.

    [atlascloud.ai/console/api-keys →](https://www.atlascloud.ai/console/api-keys)
2. ### Step 2: Add the key in Phersa

    In Phersa, open Settings, go to API keys and choose Atlas Cloud. Paste the key and click Save & verify.

3. ### Step 3: Let Phersa check it

    Phersa first checks that the key starts with apikey-, then tests it with Atlas Cloud. A key Atlas Cloud rejects is not stored. Saved keys are encrypted, and once connected the Atlas Cloud panel in Settings shows your balance in dollars.

4. ### Step 4: Generate

    In the app, pick a model that runs on Atlas Cloud. You see the cost in dollars before you generate, such as $0.08 for a 1K Nano Banana 2 image.

### MCP server details

- Provider keys are added in Phersa Settings only. The Phersa MCP server cannot read, add or change them.
- settings-keys-status shows which providers, including Atlas Cloud, are connected.
- jobs-create defaults to dry\_run=true and returns a plan without spending. dry\_run=false starts a real generation that spends the user's Atlas Cloud balance.
