What it does
This is a collection of MCP servers maintained by Avalara that provide access to tax compliance APIs. It covers tax calculation, transaction management, returns filing, business licensing, e-invoicing, exemption certificates, cross-border trade, and tax content. Developers building AI applications that need tax compliance functionality use these servers.
- Calculate real-time tax rates and amounts for transactions across different jurisdictions
- Manage tax returns, registrations, and exemption certificates through AI workflows
- Access cross-border trade duties and tariff information for international transactions
Before you enable it
An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
