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 Cline connect to MCP servers?
Cline reads MCP server configurations from its settings panel in VS Code. Add the server URL and Cline discovers all available tools on initialization.
Can Cline run MCP tools without approval?
By default, Cline asks for confirmation before executing tool calls. You can configure auto-approval rules for trusted servers in the settings.
Does Cline support multiple MCP servers at once?
