  Avalara tax-compliance systems. The overview documents a set of product-scoped servers reached through
  an MCP client, with authorization handled by Avalara''s OAuth sign-in (identity.avalara.com). Per-server
  connection URLs and the full tool inventory live on the individual product MCP pages (e.g. https://developer.avalara.com/products/avatax/mcp.md)
  and are not enumerated on the overview; captured here as the published server catalog. Connect flow:
  set up an MCP client, then authorize via Avalara OAuth.'
