Create and use API keys

Most AI tools should connect with a sign-in instead; they don’t need a key. Use an API key for your own scripts, automations, or an MCP client that can only send a header.

Create a key

1. 1Open the account menu and choose MCP and API keys.
2. 2Under API keys, choose Create key.
3. 3Name it after where you’ll use it (up to 100 characters), and if you have several workspaces, pick the one new studies made with this key should go into.
4. 4Choose Create key, then copy the key. It starts with ak_.

Use a key

Send it as a Bearer token in the Authorization header, to the MCP connector or to the API:

Authorization: Bearer ak_your_key_here

For example, to add PopsicleAI to Claude Code with a key instead of signing in:

claude mcp add --transport http popsicleai https://popsicleai.app/mcp --header "Authorization: Bearer ak_your_key_here"

Manage keys

• You can have up to 5 keys. The list shows each key’s name, workspace, the start of the key, when it was created and when it was last used.
• Delete a key with the trash icon. Anything using it stops working straight away.
• Keys can do what you can do in your studies, but can’t manage teams or billing.
