15 tools. 8 can modify or destroy data without limits.
1 destructive tool with no built-in limits. Policy required.
Last updated:
Destructive tools (wipeLogs) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.
Execute tools (runAccessibilityAudit, runAuditMode, runBestPracticesAudit) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.
Intercept sits between your agent and BrowserTools. Every tool call checked against your policy before it executes — so your agent can do its job without breaking things.

Yes. The BrowserTools server exposes 1 destructive tools including wipeLogs. These permanently remove resources with no undo. Intercept blocks destructive tools by default so they never reach the upstream server.
15 tools across 3 categories: Destructive, Execute, Read. 7 are read-only. 8 can modify, create, or delete data.
One line change. Instead of running the BrowserTools server directly, prefix it with Intercept: intercept -c browsertools.yaml -- npx -y @@AgentDeskAI/browser-tools-mcp. Download a pre-built policy from policylayer.com/policies/browsertools and adjust the limits to match your use case.
Starter policies available for each. Same risk classification, same one-command setup.
Set budgets, approvals, and hard limits across MCP servers.
