Frequently asked questions
Can I calculate sales tax for a specific address via AI?
Yes! Use the calculate_sales_tax tool. Provide the destination country, zip code, and state along with the order amount. Your agent will return the precise tax to be collected.
How do I see in which states I have a tax nexus?
Run the list_nexus_regions query. The agent will retrieve a list of all regions (states or countries) where you have configured a tax nexus in your TaxJar account.
Is it possible to validate a shipping address via AI?
Absolutely. Use the validate_tax_address tool and provide the full address details. The agent will verify the address through TaxJar to ensure it is accurate for tax purposes.
How does AutoGen connect to MCP servers?
Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call TaxJar tools during their conversation turns.
Can different agents have different MCP tool access?
Yes. AutoGen's role-based architecture lets you assign specific MCP tools to specific agents, so a querying agent has different capabilities than a reviewing agent.
Does AutoGen support human approval for tool calls?
Yes. Configure human-in-the-loop mode so agents pause and request approval before executing sensitive MCP tool calls.
