WHAT IT DOES

What override_storage_quota does on Chrome Devtools

AI agents invoke override_storage_quota to trigger actions in Chrome Devtools. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why override_storage_quota is rated High

This tool modifies browser/system configuration by overriding storage quota limits for a given origin. It's not a simple data write (it changes operational parameters), nor is it destructive (it can be reversed by removing the override). It triggers an external browser operation via the Chrome DevTools Protocol, fitting the Execute category.

From the tool's definition Override storage quota for a specific origin... New quota size in MB (optional, removes override if not provided)

RECOMMENDED RULE

The rule that runs override_storage_quota safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Chrome Devtools, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For override_storage_quota, this is the rule to start with:

override_storage_quota Rate-limited

override_storage_quota stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Chrome Devtools, apply this rule, and every override_storage_quota call is checked against it from then on.

How do I enforce a policy on override_storage_quota? +

Register the Chrome Devtools MCP server in PolicyLayer and add a rule for override_storage_quota: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Chrome Devtools. Nothing to install.

What risk level is override_storage_quota? +

Can I rate-limit override_storage_quota? +

Yes. Add a rate_limit block to the override_storage_quota rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block override_storage_quota completely? +
