Frequently asked questions
Can I automate the sending of a specific document template?
Yes! You can use the agent to map the document template and instantly send the signing request.
How can I track the signing status of a document?
Simply query the Task ID through the agent to retrieve its real-time signature status, whether pending or completed.
Do I need a paid plan to use the DottedSign API?
Access to the API generally requires an active DottedSign API subscription plan. Check the official docs for current restrictions.
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.
