Standardize Tax Logic Across Your Team

Add this MCP server to your project's `.vscode/mcp.json` file. Now, every developer on the team gets access to the same Avalara tools through Copilot's agent mode. When someone asks Copilot to handle tax, it will use `create_transaction` for consistent calculations. No more one-off scripts or devs hitting different endpoints. Everyone's on the same page.

Build with Verified Address Data

The `resolve_address` tool is now available to your whole team. Copilot can use it to validate addresses before they're saved to a database or used for a tax lookup. This stops bad data at the source. Developers can also use `get_tax_rates_by_address` to quickly check rates for different regions while building features, all without leaving VS Code.

Check Your Avalara Setup from VS Code Copilot

This MCP Server lets your team query your company's Avalara configuration. New developers can ask Copilot to `list_companies` to understand the corporate structure they're working with. It's also a great way to debug. If tax calculations seem off, any dev can ask Copilot to `list_nexus` to confirm the tax registration for a specific company, right in their editor.

Common questions about Avalara (AvaTax) MCP in VS Code Copilot

Add the server configuration to a `.vscode/mcp.json` file in your repository's root. Once you commit that file, every developer who pulls the repo will have the Avalara tools available in Copilot.

Yes. Instruct Copilot's agent to void a specific transaction code. It will use the `void_transaction` tool and can even help you write the surrounding application logic for it.

Definitely. Just ask the Copilot agent to get tax rates for a specific address. It will use the `get_tax_rates_by_address` tool to fetch the correct data from Avalara for you.

Ask the Copilot agent to run a system check on the Avalara connection. The agent uses the `get_account_check` tool to ping your account and confirm everything is working.

Your team's transaction data and addresses are passed through to Avalara via an encrypted connection. The Vinkius MCP host uses a dedicated, isolated sandbox for each request and doesn't persist any of your financial or customer data.
