Generate Code with Real Tax Data

This tool lets Cursor's agent build code that calls the AvaTax API. Instead of getting a placeholder, the agent can use `create_transaction` to get a real tax calculation and inject the response directly into your editor. This changes how you work. You're not just getting code snippets; you're getting working code that's already tested against live Avalara data. You can also `commit_transaction` or `void_transaction` right from the agent chat.

Resolve Addresses in Your Editor

Stop guessing at address formats. Highlight an address in your code, and have the agent use `resolve_address` to validate it. The corrected, standardized address can be inserted right back into your file. This is perfect for building shipping forms or customer profiles. You can also have the agent use `get_tax_rates_by_address` to quickly look up rates for a location and use that data to build out your UI logic.

Query Your Avalara Account with this MCP Server

You don't have to leave your IDE to check your Avalara configuration. Have the agent run `list_companies` to see all the entities set up in your account. Need to confirm your tax nexus? Just ask the agent to `list_nexus` for a specific company ID. It's faster than searching through a web dashboard when you're in the middle of writing code. This is what an MCP Server is for.

Common questions about Avalara (AvaTax) MCP in Cursor

Activate Cursor's agent and ask it to write the code. It can use `create_transaction` to get real-time tax and then inject the API response structure directly into your project.

Absolutely. Highlight an address in your editor and ask the agent to validate it. It will use the `resolve_address` tool and give you back the clean, standardized version from Avalara.

Just ask the agent, "List all companies in my Avalara account." It will call the `list_companies` tool and show you the results right in the chat panel.

Yes. If you have the transaction code, tell the agent to fetch it. The `get_transaction` tool will pull the full record from Avalara.

The server only proxies requests for transaction details, addresses, and company info to Avalara. Your API keys are encrypted, and the Vinkius platform processes the requests in a zero-trust, ephemeral environment. Nothing is logged or stored.
