Common questions

Is Snowflake MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: SNOWFLAKE_PASSWORD, SNOWFLAKE_PRIVATE_KEY_FILE_PWD, SNOWFLAKE_OAUTH_CLIENT_SECRET, SNOWFLAKE_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.14.4) reached the registry 44 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv), Docker on your computer.

What can I use instead?

Snowflake MCP Server NSP

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

Highlights:

Multiple authentication methods: password, key-pair, external browser, OAuth 2.0 (client credentials & bearer token), TOML connection files
TOML multi-connection config — manage production, staging, and development environments in one file
Write-safety guard — write operations are disabled by default and must be explicitly enabled
Exclusion patterns — filter out databases, schemas, or tables from discovery
--exclude-json-results flag — reduces LLM context window usage
Selective tool exclusion via --exclude_tools
Prefetch mode — pre-load table schema as MCP resources
Docker support with hardened image (DHI, nonroot user, no shell in runtime)

Quick Start

The fastest way to try it — using uvx with a TOML connection file:

# 1. Create a connections file

cat > ~/snowflake_connections.toml << 'EOF' [myconn] account = "your_account" user = "your_user" password = "your_password" warehouse = "COMPUTE_WH" database = "MY_DB" schema = "PUBLIC" role = "MYROLE" EOF

2. Run the server

uvx --python=3.13 --from mcp-snowflake-server-nsp mcp_snowflake_server \ --connections-file ~/snowflake_connections.toml \ --connection-name myconn

Claude Code

Add to your MCP client config (e.g. claude_desktop_config.json) using snowflake_connections.toml:

"mcpServers": {

"snowflake": { "command": "uvx", "args": [ "--python=3.13", "--from", "mcp-snowflake-server-nsp", "mcp_snowflake_server", "--connections-file", "/absolute/path/to/snowflake_connections.toml", "--connection-name", "myconn" ] } }
