What data can the AI access?
The AI agent authenticates as you via OAuth. It sees only the data you have permission to access in Marvin, and nothing more. It cannot access other users' data.
Is my research data sent to the AI model?
Yes, when you ask the AI to analyze a transcript or search your data, the content is sent to the AI model as part of the conversation. It is treated as a part of the chat. Review your AI provider's data policies (e.g., Anthropic, OpenAI) for how they handle conversation data.
Can the AI delete my data?
The AI cannot delete any data in Marvin. All existing tools can only read and search research data in Marvin.
Why did the AI only return 20 search results?
Search defaults to 20 results per page to keep responses fast and focused. You can ask for more (up to 100) or say "show me the next page" to paginate the results.
Why does the AI keep showing me an error when I try to use Marvin tools?
Try removing the MCP server from your AI client and reconnecting it. This refreshes the connection and re-authenticates your session, which resolves most issues.
