Set up

Add Google BigQuery 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 Google BigQuery in Runlayer

    Add Google BigQuery 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, Google BigQuery’s 9 tools show up in Claude Code’s own tool list (supported Claude Code versions).

  3. 3

    Sign in to Google BigQuery

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

  4. 4

    Use Google BigQuery from Claude Code

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

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 Google BigQuery 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.
