Frequently asked questions
What can I do with the Readwise connector?
You can list, search, create, update, and delete highlights, browse books by source or category, manage tags, access your daily spaced repetition review, and export all data incrementally for analysis or backup.
How does the daily review feature work?
The daily review tool retrieves highlights selected by Readwise's spaced repetition algorithm, helping your AI agent surface the most important passages at the optimal retention interval.
Can I filter books by where they came from?
Yes, you can filter by source (Kindle, Instapaper, Pocket, web, Apple Books) or by category (books, articles, tweets, podcasts) to quickly find the content you need.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
