Arcjet MCP Server

other

Arcjet is a security layer developers drop into an application to handle bot detection, rate limiting, prompt injection detection, and sensitive data protection, and Neotask's agent connects to it so a developer can check or adjust those controls from a conversation instead of digging through a dashboard. Ask what rate limiting rules are currently active on a given app, or whether bot detection flagged anything unusual in the last day, and the agent queries Arcjet directly for the answer. It can also help adjust configuration, for example tightening a rate limit rule or reviewing what counts as sensitive data under the current policy. This is built for developers and the people maintaining an app's runtime security posture who want a faster way to check what's actually configured, not a replacement for setting up Arcjet in the first place.

• Check which bot detection, rate limiting, and prompt injection rules are active on an app
• Review recent security events without opening a separate dashboard
• Adjust rule configuration, like tightening a rate limit, through a conversation

What you can automate

Rule inspection	Reads the current bot detection, rate limiting, and sensitive data protection configuration for a connected app
Event review	Surfaces recent flags from bot detection or prompt injection detection
Rule adjustment	Updates rate limiting and related security rule settings

Real workflows

Checking a rate limit after a traffic spike

A developer notices unusual traffic on an app and asks the agent what rate limiting rules Arcjet currently has active for it. The agent pulls the configuration, shows the existing thresholds, and the developer decides whether to tighten them right there in the conversation.

Reviewing prompt injection flags before a release

Before shipping a new AI feature, a developer asks the agent to check whether Arcjet's prompt injection detection has flagged anything recently on the related endpoint. The agent reports back what it finds, giving the team a quick read on exposure before the release goes out.

Frequently asked questions

Do I need Arcjet already set up on my app for this to work?

Yes, the agent reads and adjusts an existing Arcjet configuration, it doesn't set Arcjet up on an app from scratch.

Can the agent turn off a security rule entirely?

It can adjust rule configuration within what Arcjet exposes, so treat any change through the agent with the same caution as a change made directly in the Arcjet dashboard.

What kind of sensitive data protection can it check?

Whatever sensitive data rules are configured for the app, such as patterns Arcjet is set to detect and block.

Is this useful for someone who isn't a developer?

It's built around application security configuration, so it's most useful for developers or whoever owns an app's runtime protection settings.
