Integrate Arcjet security into a Vercel AI SDK (v7) application using @arcjet/guard — wrap agent tools with guard checks, enforce rules on risky app actions, and emit audit events joined by one correlation ID. Use when asked to add Arcjet to an AI SDK app, protect or rate limit agent tool calls, guard AI agent actions, or audit what an agent did.
Integrate Arcjet security into a Claude Agent SDK agent using @arcjet/guard — wrap tool() handlers, screen inbound prompts with UserPromptSubmit, and deny unwrapped built-in/MCP tools with PreToolUse. Use when asked to add Arcjet to a Claude Agent SDK or Claude Code agent, rate limit its tools, screen inbound messages, or block prompt injection / PII.
Integrate Arcjet security into a Vercel Eve agent using @arcjet/guard — add guard gates to tools and connections, screen inbound messages, and record agent lifecycle events correlated to the session. Use when asked to add Arcjet to an Eve agent, rate limit its tools, guard connection access, or screen inbound messages.
Integrate Arcjet security into a Genkit JS agent using @arcjet/guard — wrap ai.defineTool, put guardMiddleware on generate({ use }) for unwrapped / MCP / filesystem tools, and read a caller-owned id from generate({ context }). Use when asked to add Arcjet to genkit, rate limit its tools, screen inbound messages, or block prompt injection / PII.
Integrate Arcjet security into a LangChain JS createAgent using @arcjet/guard — wrap tool() / StructuredTool, put guardMiddleware on createAgent({ middleware }) for MCP / unwrapped tools, and read configurable.thread_id for correlation. Use when asked to add Arcjet to langchain createAgent, rate limit its tools, screen inbound messages, or block prompt injection / PII. This is LangChain JS, not the Python page.
Integrate Arcjet security into a LangGraph Graph API agent using @arcjet/guard — wrap tool() / StructuredTool, wrap ToolNode for unwrapped MCP tools, and read thread_id for correlation. Use when asked to add Arcjet to a LangGraph StateGraph / ToolNode agent, rate limit its tools, screen inbound messages, or block prompt injection / PII.
Integrate Arcjet security into a Mastra agent using @arcjet/guard — wrap createTool execute, screen input/output with a Processor tripwire, and gate unwrapped MCP/workspace tools with hooks. Use when asked to add Arcjet to a Mastra agent, rate limit its tools, screen inbound messages, or block prompt injection / PII.
Integrate Arcjet security into an OpenAI Agents text Agent using @arcjet/guard — wrap tool({ execute }), screen inbound before run(), and read a caller-owned id from runContext.context. Use when asked to add Arcjet to @openai/agents, rate limit its tools, screen inbound messages, or block prompt injection / PII.
Integrate Arcjet security into a Strands Agents JS app using @arcjet/guard — wrap tool({ callback }), put guardHooks on Agent({ plugins }) for unwrapped / MCP / vended tools, and read a caller-owned id from invocationState. Use when asked to add Arcjet to strands-agents, rate limit its tools, screen inbound messages, or block prompt injection / PII.
