Set up

Add Snowflake to Claude Code in four steps

Admins approve the server once. Everyone in Claude Code then gets it through the same governed connection.

  1. 1

    Approve Snowflake in Runlayer

    Add Snowflake from the catalog and choose who can use it and which of its tools are allowed.

  2. 2

    Connect Claude Code to Runlayer

    Runlayer’s CLI installs the Runlayer Plugin natively in Claude Code, and an Anthropic org install also reaches Claude Code. With direct tool listing turned on for your deployment, Snowflake’s 8 tools show up in Claude Code’s own tool list (supported Claude Code versions).

  3. 3

    Sign in to Snowflake

    Each user signs in to Snowflake with OAuth. Runlayer keeps the tokens out of the client’s configuration.

  4. 4

    Use Snowflake from Claude Code

    Snowflake’s approved tools appear in Claude Code. Every call is checked against policy and recorded.

Tools

8 Snowflake tools in Claude Code

Runlayer policy decides which of these Claude Code users can call.

  • Describe semantic view

    Describe a semantic view.

  • Get semantic view ddl

    Get the DDL for a semantic view.

  • List semantic views

    List all semantic views in the account, database, or schema.

  • Query semantic view

    Writes and runs a statement to query a semantic view using DIMENSIONS, METRICS, and/or FACTS.

  • Run Snowflake query

    Run a SQL query in Snowflake.

  • Show semantic dimensions

    Show all semantic dimensions in the account, database, or schema.

  • Show semantic metrics

    Show all semantic metrics in the account, database, or schema.

  • Write semantic view query tool

    Writes a query statement to query a semantic view using DIMENSIONS, METRICS, and/or FACTS.

Control

What Runlayer can see and stop in Claude Code

Some controls apply to every client at the gateway. Others depend on what Claude Code exposes to Runlayer.

  • Gateway policy (available)

    Every Snowflake call from Claude Code passes through Runlayer, where your policies can allow, alert, mask, or block it.

  • Audit trail (available)

    Each call is recorded with the user, Claude Code as the client, the tool, and the policy and scanner decisions.

  • Client hooks (available)

    Capture supported prompts, reasoning, local and MCP tool calls, responses, and scanner decisions in real time.

  • Anthropic inference hooks (available)

    With Claude Enterprise, Anthropic sends each governed Claude Code prompt to Runlayer before inference, with nothing installed on devices (Anthropic beta).

  • OTLP telemetry (available)

    Claude Code can export OpenTelemetry logs to Runlayer for observe-only session reconstruction.

  • Stop a call before it runs (available)

    Runlayer can deny a tool call before Claude Code runs it.

  • Block output after it runs (available)

    Runlayer can block a tool’s output before Claude Code’s model sees it.

  • Redact output in place (available)

    Runlayer can mask sensitive parts of a tool’s output in Claude Code and pass the rest through.

In Claude Code

  • When a tool fails, Runlayer records the error but cannot hide it.
