Overview

What is Mcp Snowflake Server Nsp?

A Model Context Protocol (MCP) server that connects AI assistants to Snowflake, enabling SQL queries, schema exploration, and data insights directly from an LLM client.

How to use Mcp Snowflake Server Nsp?

Configure the server using a TOML connection file to manage multiple environments (e.g., production, staging), choose an authentication method (password, key-pair, external browser, or TOML file), and invoke it with optional flags such as --exclude-json-results, --exclude_tools, or --prefetch to pre-load schemas.
