How to use Snowflake with VS Code

You want Snowflake inside VS Code so it can answer questions from warehouse data, audit accessible data assets, validate a table before building a query, and compare records across reporting periods — without you copy-pasting between tabs. Here is the whole setup, once.

Create your Snowflake gateway

The gateway is the thing VS Code connects to, and it is where you decide which Snowflake tools an agent may use. You create it once and every client reuses it.

  1. Create an Arcade account

    Sign up and open the dashboard. The free tier is enough to follow this through.

  2. Create an MCP Gateway and select your Snowflake tools

    In the dashboard, create a gateway and pick the Snowflake tools you want to expose. The gateway is what your client connects to, and it is where tool access is decided.

  3. Copy your gateway URL

    Every client below needs it.

Connect the gateway to VS Code

  1. Add the server

    VS Code 1.107.0 or higher. Command Palette → MCP: Add Server… → choose HTTP, paste your gateway URL, and name it something like mcp-arcade.

  2. Start it and authenticate

    Click Start next to the server in mcp.json or under Extensions → MCP Servers - Installed, then approve the Arcade sign-in and consent screens.

  3. Try it out

    Open the chat pane, switch to Agent mode, and ask it to use one of your Snowflake tools.

Get started with Snowflake prompts

VS Code can now act on your Snowflake account. Click a prompt to copy it.

Keep access tied to each user's Snowflake role, and restrict agents to discovery and read-only SELECT queries. Pair it with Contextual Access policies so an agent can inspect data without gaining write or administrative access.
