OSS Snowflake MCP Server

This community MCP server previously provided tooling for Snowflake Cortex AI, object management, and SQL orchestration. It is no longer supported. For all new and existing use cases, please use the official Snowflake MCP Server instead. It runs locally over stdio via the published package.

People connecting database tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install OSS Snowflake MCP Server

before you install - you'll need

Set SNOWFLAKE_MCP_ENDPOINT, SNOWFLAKE_ACCOUNT, SNOWFLAKE_USER, SNOWFLAKE_PASSWORD, SNOWFLAKE_PRIVATE_KEY, SNOWFLAKE_PRIVATE_KEY_FILE_PWD before connecting.

Claude Code

claude mcp add snowflake-labs-mcp -- uvx snowflake-labs-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "snowflake-labs-mcp": {
      "command": "uvx",
      "args": [
        "snowflake-labs-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
