Control
What Runlayer can see and stop in Claude Cowork
Some controls apply to every client at the gateway. Others depend on what Claude Cowork exposes to Runlayer.
Gateway policy (available)
Every Looker call from Claude Cowork passes through Runlayer, where your policies can allow, alert, mask, or block it.
Audit trail (available)
Each call is recorded with the user, Claude Cowork as the client, the tool, and the policy and scanner decisions.
Anthropic inference hooks (available)
Anthropic Inference hooks let Runlayer check Claude Cowork prompts before inference.
OTLP telemetry (available)
Claude Cowork can send supported OpenTelemetry events to Runlayer for observe-only session visibility.
Stop a call before it runs (available)
Runlayer can reject a Claude Cowork prompt before Anthropic runs it, which stops the whole request rather than one tool call.
Block output after it runs (available)
Because Runlayer checks the full prompt, tool results in it can be blocked before the model sees them.
Redact output in place (not available)
Runlayer cannot mask content in Claude Cowork. The gateway still applies policy to the call.
