SingleStore MCP Server

Model Context Protocol (MCP) is a standardized protocol designed to manage context between large language models (LLMs) and external systems. This repository provides an installer and an MCP Server for Singlestore, enabling seamless integration.

With MCP, you can use Claude Desktop, Claude Code, Cursor, or any compatible MCP client to interact with SingleStore using natural language, making it easier to perform complex operations effortlessly.

💡 Pro Tip: Not sure what the MCP server can do? Just call the /help prompt in your chat!

Requirements

• Python >= v3.10.0
• uvx installed on your python environment
• VS Code, Cursor, Windsurf, Claude Desktop, Claude Code, Goose or any other MCP client

Getting started

Getting started

First, install the SingleStore MCP server with your client.

Standard config works in most of the tools:

{
  "mcpServers": {
    "singlestore-mcp-server": {
      "command": "uvx",
      "args": [
        "singlestore-mcp-server",
        "start"
      ]
    }
  }
}

No API keys, tokens, or environment variables required! The server automatically handles authentication via browser OAuth when started.

Using Docker

NOTE: An API key is required when using Docker because the OAuth flow isn’t supported for servers running in Docker containers.

{
  "mcpServers": {
    "singlestore-mcp-server": {
      "command": "docker",
      "args": [
        "run", "-i", "--rm", "--init", "--pull=always",
        "-e", "MCP_API_KEY=your_api_key_here",
        "singlestore/mcp-server-singlestore"
      ]
    }
  }
}

You can build the Docker image yourself:

docker build -t singlestore/mcp-server-singlestore .

For better security, we recommend using Docker Desktop to configure the SingleStore MCP server—see this blog post for details on Docker’s new MCP Catalog.

Development

Prerequisites

• Python >= 3.11
• uv for dependency management

Setup

1. Clone the repository:

git clone https://github.com/singlestore-labs/mcp-server-singlestore.git
cd mcp-server-singlestore

1. Install dependencies:

uv sync --dev

1. Set up pre-commit hooks (optional but recommended):

uv run pre-commit install

Development Workflow

# Quick quality checks (fast feedback)
./scripts/check.sh

# Run tests independently
./scripts/test.sh

# Comprehensive validation (before PRs)
./scripts/check-all.sh

# Create and publish releases
./scripts/release.sh

Running Tests

# Run test suite with coverage
./scripts/test.sh

# Or use pytest directly
uv run pytest
uv run pytest --cov=src --cov-report=html

Code Quality

We use Ruff for both linting and formatting:

# Format code
uv run ruff format src/ tests/

# Lint code
uv run ruff check src/ tests/

# Lint and fix issues automatically
uv run ruff check --fix src/ tests/

Release Process

Releases are managed through git tags and automated PyPI publication:

1. Create release: ./scripts/release.sh (interactive tool)
2. Automatic publication: Triggered by pushing version tags
3. No manual PyPI uploads - fully automated pipeline

See scripts/dev-workflow.md for detailed workflow documentation.
