StarRocks Official MCP Server tools

6

** Execute a SELECT query or other commands that return a ResultSet (e.g., `SHOW`, `DESCRIBE`). Optionally write the full result to a local file instead of returning it inline — useful for results too large to fit in the model context.

** Execute a DDL (`CREATE`, `ALTER`, `DROP`), DML (`INSERT`, `UPDATE`, `DELETE`), or other StarRocks command that does not return a ResultSet.

** Analyze a query and get analyze result using query profile or explain analyze.

** Executes a SQL query, loads the results into a Pandas DataFrame, and generates a Plotly chart using a provided Python expression. Designed for visualization in supporting UIs.

** Get an overview of a specific table: columns (from `DESCRIBE`), total row count, and sample rows (`LIMIT 3`). Uses an in-memory cache unless `refresh` is true.

** Get an overview (columns, row count, sample rows) for _all_ tables within a specified database. Uses the table-level cache for each table unless `refresh` is true.

Overview

What is StarRocks Official MCP Server?

The StarRocks Official MCP Server acts as a bridge between AI assistants and StarRocks databases. It enables direct SQL execution, database exploration, data visualization via charts, and retrieval of detailed schema and data overviews without requiring complex client-side setup.

How to use StarRocks Official MCP Server?

Install uv (Python package manager) and configure an MCP host (e.g., Claude Desktop) to launch the server. Connection is set via environment variables (STARROCKS_URL or individual vars like STARROCKS_HOST, STARROCKS_PORT, etc.) or a Streamable HTTP endpoint. Run with uv run mcp-server-starrocks and optional flags like --mode stdio or --mode streamable-http --port 8000.

Key features of StarRocks Official MCP Server

  • Direct SQL execution: read_query (SELECT) and write_query (DDL/DML).
  • Database exploration via starrocks:// resources (list databases, tables, schemas).
  • System information access through proc:// resource path.
  • Detailed overviews: table_overview and db_overview with row counts, samples.
  • Data visualization: query_and_plotly_chart generates Plotly charts from query results.
  • Intelligent in‑memory caching of table and database overviews (bypassable).

Use cases of StarRocks Official MCP Server

  • AI assistant querying StarRocks to answer business questions in natural language.
  • Generating charts and visualizations directly from SQL results.
  • Exploring database schema and contents for context‑aware LLM interactions.
  • Monitoring StarRocks cluster internals via the proc:// resource.
  • Automating data analysis workflows without a custom SQL client.

Frequently asked questions

1

What are the prerequisites to run the server?

Python 3.11+, a reachable StarRocks cluster (FE service, default `localhost:9030` over MySQL protocol), and the `uv` package manager.

2

How do I configure the StarRocks connection?

Use either a single `STARROCKS_URL` (e.g., `root:password@localhost:9030/my_db`) or individual environment variables (`STARROCKS_HOST`, `STARROCKS_PORT`, `STARROCKS_USER`, `STARROCKS_PASSWORD`, `STARROCKS_DB`). The URL takes precedence.

3

What transport modes are supported?

`stdio` (default, for MCP hosts), `streamable-http` (recommended for RESTful APIs), and `sse` (deprecated, not recommended). Set via `--mode` flag or `MCP_TRANSPORT_MODE` env var.

4

Can the server connect using Arrow Flight SQL?

Yes. Set the `STARROCKS_FE_ARROW_FLIGHT_SQL_PORT` environment variable to enable high‑performance Arrow Flight SQL protocol via ADBC drivers.

5

Where do output files from `read_query` get saved?

By default to `~/.mcp-server-starrocks/output/` (controlled by `STARROCKS_MCP_OUTPUT_DIR`). Absolute paths bypass this setting. Files are written on the machine running the MCP server.
