For AI agents: a documentation index is available at the root level at /llms.txt. Append /llms.txt to any URL for a page-level index, or .md for the markdown version of any page.
This page is for MCPs, version MCP servers.
For other versions, use one of these documentation indexes:
- Overview (default): https://avalara.ferndocs.com/mcp/overview/llms.txt
- MCP servers: https://avalara.ferndocs.com/mcp/mcp-servers/llms.txt
To connect to Avalara MCP servers, you need:
Avalara subscription — an active Avalara account.
An AI client — programmatic clients built with FastMCP or any MCP client library that supports OAuth 2.1 authorization.
A modern web browser — required for the OAuth 2.1 authorization flow.
