Avalara MCP servers

To connect to Avalara MCP servers, you need to have:
  • Avalara subscription: You must have an active Avalara account with production credentials, sandbox credentials, or both depending on which MCP environment you use
  • An AI client: Programmatic clients built using FastMCP or any other equivalent MCP client libraries that support OAuth 2.1 authorization
  • A modern web browser: Required for the OAuth 2.1 authorization flow.

Each MCP server supports both production and sandbox environments. Use sandbox endpoints to test and validate your AI agent workflows without affecting production data.
