Query Spark SQL clusters via Thrift/HiveServer2. Works with Spark, EMR, Hive, Impala.
To add Spark SQL to Claude, run the install command below or copy the ready-made config for Claude Code, Claude Desktop, Cursor and VS Code further down. Restart your client after adding it and its tools show up in your next conversation. It needs 7 environment variables, listed below.

Run this in a terminal to add the server to Claude Code.
What this does
Spark SQL exposes a set of tools to Claude over the Model Context Protocol. After you add it to claude_desktop_config.json (snippet above) and restart Claude Desktop, those tools become callable inside any conversation.
Requirements
This server needs the following environment variables to be set before it can run:
SPARK_HOST SPARK_PORT SPARK_DATABASE SPARK_AUTH SPARK_USERNAME SPARK_PASSWORD SPARK_KERBEROS_SERVICE_NAME
Set these via the env object in your MCP config (see claude_desktop_config.json snippet above).
Frequently asked questions
How do I install Spark SQL?
Run the Claude Code command in the install section to add Spark SQL to Claude Code, or copy the ready-made config for your client from the install section on this page. Restart your client afterwards and the tools appear in your next conversation.
Which clients work with Spark SQL?
This page carries setup and config for Claude Code, Claude Desktop, Cursor and VS Code. Any other MCP client that accepts a standard server config can connect to Spark SQL as well.
Does Spark SQL need an API key?
Yes. Before it can run, set these environment variables: SPARK_HOST, SPARK_PORT, SPARK_DATABASE, SPARK_AUTH, SPARK_USERNAME, SPARK_PASSWORD, SPARK_KERBEROS_SERVICE_NAME. They go in the env block of your MCP config.
