Accounts and tokens
- No Vizbl account is needed for guides, cost estimates, conversion, file hosting, AR links, QR codes and widget snippets.
- Importing, uploading and deleting models needs a Vizbl account with Developer API access and a secret API key. Imports use your account's normal conversion quota.
- Shopper actions on your site, such as opening a model in AR, spend tokens from your Vizbl balance as usual.
- The connector does not create accounts, change billing, or generate images, video or audio.
How your data is handled
Your API key is encrypted into the OAuth tokens held by your client. The server keeps no copy and no database of connections.
Your model files are downloaded in memory, forwarded to the Vizbl Developer API under your account, and then discarded. Imported models live in your Vizbl library, as if you had uploaded them in the app.
Your conversation stays with your client. Only the arguments of a tool call reach the server; the connector never requests chat history, memory, or unrelated files.
The full privacy policy for the connector is published at mcp.vizbl.com.
