Arcjet is the runtime security platform that ships with your AI code. Enforce budgets, stop prompt injection, detect bots, and protect personal information - configured by developers or coding agents via MCP and enforced inline in your application code with real identity and session context.
Arcjet runs server-side. Bot protection advanced client signals are an optional extra layer of defense.
This extension will optionally set the ARCJET_KEY environment variable on your selected Vercel project(s) so it's ready to deploy immediately.
Once installed, point your coding agent at the Arcjet agent get started guide which uses Arcjet's MCP server to automatically configure security protections in code (or implement them manually using our get started guide).
Once deployed, your coding agent can monitor Arcjet for attacks and proactively configure rules to mitigate them.
