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://json-repair.agentdiet.dev/v1/jailbreak-scan)
Output
Returns a structured object containing the scan result for the submitted text, including detection of any hidden prompt injection attempts, jailbreak payloads, or adversarial instructions, along with sanitized output safe for downstream LLM consumption.
Example use cases
Protect agent from malicious web scrape
“I just scraped this product page to summarize for a customer, but before you pass it to the summarizer, scan the raw HTML for any hidden prompt injections that might hijack your behavior.”
Sanitize email before LLM processing
“Before you extract the action items from this incoming email, run the body through the jailbreak firewall — I want to make sure there are no embedded adversarial instructions trying to manipulate you.”
Validate MCP tool response safety
“That MCP tool just returned a big JSON blob — can you scan the text content inside it for any hidden jailbreak payloads before we feed it into the next agent step?”
Technical details
Endpoint
GEThttps://json-repair.agentdiet.dev/v1/jailbreak-scan?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent is about to process content from untrusted external sources — scraped web pages, user-submitted text, emails, third-party API responses, or MCP/A2A tool outputs — and you need a dedicated security layer to detect and strip adversarial prompt injections before they reach your LLM. Prefer this over generic content filters when the threat model is specifically indirect prompt injection and jailbreak attempts targeting agent behavior.
Side effects
- Empty or missing 'text' parameter returns a validation error
- Extremely large payloads may be truncated or rejected
- Sophisticated steganographic injections may evade detection
- Non-text binary content may produce unreliable results
- Payment failure (HTTP 402) if x402 micropayment is not completed
