Overview

What is SingleStore MCP Server?

The SingleStore MCP Server is a Model Context Protocol server that provides tools for querying SingleStore databases, describing schemas, and generating ER diagrams. It supports SSL with automatic CA bundle fetching and is built with TypeScript. This server is designed for developers and data analysts who want to interact with SingleStore through MCP-compatible clients like Claude Desktop.

How to use SingleStore MCP Server?

Install via Smithery (npx -y @smithery/cli install @madhukarkumar/singlestore-mcp-server --client claude) or clone, install dependencies (npm install), build (npm run build).

Run with node build/index.js. Tools include list_tables, query_table, describe_table, generate_er_diagram, run_read_query, create_table, generate_synthetic_data, and optimize_sql.

FAQ from SingleStore MCP Server

What runtime environment does the SingleStore MCP Server require?

Node.js 16 or higher and npm or yarn.

How do I connect the server to my SingleStore database?

Set the environment variables SINGLESTORE_HOST, SINGLESTORE_PORT, SINGLESTORE_USER, SINGLESTORE_PASSWORD, and SINGLESTORE_DATABASE. The server automatically fetches the SingleStore CA bundle for SSL.

Can I use this server over HTTP instead of stdio?

Yes. Enable the SSE HTTP server by setting SSE_ENABLED=true and optionally SSE_PORT (default 3333). The server then provides endpoints like /sse, /tools, and /call-tool.

What is the difference between `query_table` and `run_read_query`?

query_table executes any custom SQL query, while run_read_query restricts execution to read-only SELECT queries only.

How can I generate synthetic data for a table?

Use the generate_synthetic_data tool with parameters for the table name, number of rows, optional column generators, and batch size. The tool supports sequence, values, and formula generator types.
