## Avalara MCP servers

Avalara Model Context Protocol (MCP) 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. More services will be added over time.

### How to connect:

Step 1: Set up the MCP client

Follow the steps provided on the individual MCP server pages.

Step 2: Authorize access

-   When prompted, your MCP client redirects you to Avalara's secure sign in page
-   Sign in with your Avalara credentials
-   Review the permissions requested by the client for access to specific MCP server capabilities
-   Grant consent to complete the OAuth flow.

### Troubleshooting common issues:

-   Connection failed: Verify your Avalara account status and internet connection.
-   Permission denied: Make ensure your account has access to the requested services.
-   HTTP 429 (Too Many Requests): You've exceeded the server's rate limit.
    -   \- Wait a few minutes before retrying.
    -   \- Check the server's rate limit details on its individual page.
