StarRocks/mcp-server-starrocks
The StarRocks MCP Server is the official Model Context Protocol bridge between AI assistants and StarRocks clusters. It connects to a StarRocks frontend service over the MySQL protocol, by default at localhost:9030, and exposes database work as MCP tools so a client needs no additional driver setup. Tools include read_query for SELECT statements and write_query for DDL and DML commands. Database exploration is offered through starrocks:// resources that list databases and tables and return table schemas, while internal metrics and cluster state are reachable under a proc:// resource path. Two aggregate tools give condensed context: table_overview returns column definitions, row counts and sample rows for one table, and db_overview does the same across an entire database. Both overviews are cached in memory to make repeated requests cheaper, and the cache can be bypassed on demand. A query_and_plotly_chart tool executes a query and generates a Plotly chart from the result set. The server targets Python 3.11 or newer and is managed with uv, which resolves dependencies and creates the environment on first run, so the MCP host can launch it with uv run and no manual install step. Transport modes are selected with a mode flag covering stdio, http and streamable-http, with host and port options for the HTTP modes; streamable HTTP is the recommended mode and SSE is documented as deprecated. A test flag verifies connectivity before wiring the server into a client. Connection settings come from environment variables, either individually via STARROCKS_HOST, STARROCKS_PORT, STARROCKS_USER, STARROCKS_PASSWORD and STARROCKS_DB, or as a single STARROCKS_URL connection string; on macOS the password can instead be read from the Keychain. It is aimed at analysts and engineers who want conversational access to StarRocks data.
