Overview

What is Avalara AvaTax MCP Server by CData?

This read-only MCP Server allows LLMs (like Claude Desktop) to query live data from Avalara AvaTax, powered by the CData JDBC Driver for Avalara AvaTax. It wraps the driver, exposing tax data as relational SQL models through a simple MCP interface so LLMs can retrieve live information via natural language — no SQL required.

How to use Avalara AvaTax MCP Server by CData?

Clone the repository, build with mvn clean install, download and license the CData JDBC Driver for Avalara AvaTax, configure a connection string using the driver’s utility, create a .prp file with JDBC connection properties, and add the server to your client’s MCP configuration (e.g., claude_desktop_config.json). The server runs over stdio and must be on the same machine as the client.

FAQ from Avalara AvaTax MCP Server by CData

Is this server read-only?

Yes. The project builds a read-only MCP server. For full read, write, update, delete, and action capabilities, CData offers a separate MCP Server (beta).

What runtime and dependencies are required?

Java (to run the JAR), the CData JDBC Driver for Avalara AvaTax (downloaded separately and licensed), and Maven (for building). The server is packaged as a JAR file.

Where does the data live when querying?

The server connects directly to Avalara AvaTax’s live data over the internet using the CData JDBC Driver. The driver does not store a local copy; queries return current data from the source.

What transport and authentication methods does it use?

The server uses stdio transport (local client only). Authentication is handled through the JDBC connection string, which uses OAuth (e.g., InitiateOAuth=GETANDREFRESH) for Avalara AvaTax.

Are there any known limitations?

The server is read-only. It only supports SQL SELECT queries for data retrieval; write, update, and delete operations are not available in this version.
