Frequently asked questions
Can the AI automatically validate a shipping address before I calculate the tax?
Yes! Use the resolve_address tool with the full address string. Your agent will return the validated and formatted address, ensuring that the subsequent tax calculation uses the correct jurisdiction data.
How do I void a transaction that was recorded incorrectly?
Simply ask the agent to run the void_transaction tool with the specific transaction code and company code. It will instantly update the status in your AvaTax account.
Is it possible to check my company's tax nexus settings through the AI?
Yes. The list_nexus_by_company tool allows you to audit all active tax jurisdictions where your company is registered, ensuring you are collecting taxes where required.

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.
