How this service works
Scans untrusted web pages, emails, MCP responses, or A2A payloads for hidden prompt injections and returns sanitized text. (Live x402 v2, IETF MPP & MCP endpoint at https://shopify-intel.agentdiet.dev/v1/jailbreak-scan)
Output
Returns a JSON object indicating whether a prompt injection or jailbreak payload was detected in the submitted text, along with sanitized or flagged content safe for downstream agent consumption.
Example use cases
Sanitize scraped web content before agent use
“I scraped this article HTML to feed into my research agent, but I'm worried it might have hidden prompt injections — can you scan it and give me the clean, safe version?”
Check inbound email for adversarial instructions
“This email came from an unknown sender and my agent is about to summarize it — first scan it for any embedded jailbreak or prompt injection attempts hidden in the body text.”
Validate MCP tool response before acting
“My agent just got back a response from an external MCP tool — before it acts on that output, can you run it through the prompt injection firewall to make sure it's not trying to hijack my agent?”
Technical details
Endpoint
GEThttps://shopify-intel.agentdiet.dev/v1/jailbreak-scan?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent is about to consume text from untrusted external sources — scraped web pages, inbound emails, third-party MCP/A2A tool responses, or user-supplied content — and you need a dedicated security layer to catch indirect prompt injection attacks before they can hijack agent behavior. Prefer it over general-purpose content filters when the threat model is specifically adversarial agent manipulation rather than generic content moderation.
Side effects
- Missing required 'text' parameter returns a 400 error
- Empty string input rejected due to minLength:1 constraint
- Payment not completed (HTTP 402) if x402 micropayment not satisfied
- Very long payloads may be truncated or rejected
- False negatives possible for novel or obfuscated injection techniques
- Network timeout on large HTML documents
