Add Snowflake-Labs mcp server

[jasonsum]

Description

Add MCP server for Snowflake from Snowflake-Labs

Server built by members of Snowflake's Solution Innovation Team:
Jason Summer
Tyler White
Tony Gordon, Jr

Server Details

This Snowflake MCP server provides tooling for Snowflake Cortex AI, object management, and SQL orchestration, bringing these capabilities to the MCP ecosystem. When connected to an MCP Client users can leverage these features.

The MCP server currently supports the below capabilities:

Cortex Search: Query unstructured data in Snowflake as commonly used in Retrieval Augmented Generation (RAG) applications.
Cortex Analyst: Query structured data in Snowflake via rich semantic modeling.
Cortex Agent: Agentic orchestrator across structured and unstructured data retrieval
Object Management: Perform basic operations against Snowflake's most common objects such as creation, dropping, updating, and more.
SQL Execution: Run LLM-generated SQL managed by user-configured permissions.
Semantic View Querying: Discover and query Snowflake Semantic Views

Motivation and Context

Currently listed MCP servers for Snowflake lack capabilities supported by Snowflake. This MCP server introduces a richer feature set with additional fine-grained controls and full support for all Snowflake authentication methods.

How Has This Been Tested?

Yes. All tools have been tested and several hundred Snowflake customers are using the MCP server in Cursor, Claude for Desktop, goose from Block, VSCode with GitHub Copilot, etc.
