Preview access · not provider authentication
The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Convex, so you can see the experience inside your AI.
It does not authenticate your account with Convex. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ
Questions Convex owners ask.
- 01
What is the difference between run_query and run_mutation?
Use run_query for read-only operations that fetch data. Use run_mutation when you need to write, update, or delete data transactionally in your database.
- 02
Can I call external APIs using this server?
Yes, by using the run_action capability. Actions in Convex are designed for side effects like calling third-party APIs or performing long-running tasks.
- 03
How do I reference functions in subdirectories?
You can use run_query with colon notation (e.g., 'folder/file:function') or use run_function which accepts URL-style identifiers with slashes.
