## Avalara MCP Servers


[MCP (Model Context Protocol)](https://modelcontextprotocol.io/docs/getting-started/intro)   servers connect AI applications with Avalara's tax compliance systems in a standardized way. MCP servers allow partners and developers to integrate AI-driven tax workflows, automate cross-border compliance, and access Avalara's regularly updated tax content.

Avalara-supported MCP servers include AvaTax, Returns, E-Invoicing and Live Reporting, Tax Registrations and Business Licenses and Exemption Certificate Management, Cross Border Trade, and Tax Content. More services will be added over time.



### What you can do:

1. Query real-time tax rates and calculations
2. Access compliance monitoring and regulatory updates
3. Manage exemption certificates, business licenses, and returns
4. Retrieve documentation and guidance
