Connect Snowflake

Connect Snowflake to Claude Tag so it can run read-only queries on your warehouse. Snowflake has no preset, so it is added as a custom credential.

Claude Tag is in public beta. Features and behavior described here may change before general availability.

Note: Connections are added inside an Access bundle. At claude.ai/admin-settings/claude-tag, open Access bundles in the left navigation, click into a bundle (or Create one), and go to its Credentials tab.

Connecting Snowflake lets Claude run queries against your warehouse from any channel under the bundle's scope. Add it as a custom credential with Connect another app; Snowflake has no preset button in the picker.

This is an HTTP API connection, not a personal claude.ai connector.

Create the credential in Snowflake

Create a dedicated Snowflake user for the agent with a read-only role scoped to the databases and schemas Claude should query. Generate a programmatic access token for that user.

Snowflake's guide for the SQL REST API and authentication is at docs.snowflake.com.

Add the connection to a bundle

In the bundle, click Connect another app at the bottom and choose Bearer. Bearer is the only supported credential type for Snowflake; key-pair authentication is not currently supported.

Field	Value
Credential type	Bearer
Custom headers	Add a row with Name Authorization, Prefix Bearer , and Value set to the programmatic access token from Snowflake
Allowed websites	<your-account>.snowflakecomputing.com

Replace <your-account> with your Snowflake account identifier. To change the host later, open the ⋮ menu on this connection in the bundle's Credentials tab and choose Edit.

The Agent Proxy injects the credential at the network boundary; the model and the sandbox are not given the key. See how Agent Proxy works.

Verify the connection

In a channel under the bundle's scope, in a new thread:

@Claude what can you access from this channel?

Snowflake appears in the list once the connection is live. New connections apply to new threads only.
