Arcjet JS SDK is an Apache-2.0 JavaScript monorepo that adds runtime security checks to AI apps, agents and HTTP endpoints. It ships framework SDKs (Next.js, Node.js, Bun, Deno, Fastify, NestJS) plus a Guard API for agent tool calls, MCP handlers, queue workers and background jobs that have no HTTP request object. Features include prompt injection detection, sensitive-information detection (PII, credit cards, custom patterns) and token-bucket, fixed-window and sliding-window rate limiting.
TL;DR Arcjet JS SDK: open-source guardrails for AI agents, MCP handlers and HTTP endpoints with prompt-injection and PII detection and rate limiting.
