Arcjet is the runtime security platform that ships with your code. Enforce budgets, stop prompt injection, detect bots, and protect personal information with Arcjet's AI security building blocks - configured by developers or coding agents via MCP, CLI, SDK and enforced inline in your application code with real identity and session context.
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 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.
