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/rag-poison-shield)
Output
Returns a JSON object indicating whether prompt injection or jailbreak content was detected in the submitted text, along with sanitized output safe for downstream LLM or agent consumption.
Example use cases
RAG pipeline poisoning defense
“Before my agent processes these retrieved documents from the web, scan them for any hidden prompt injection payloads — I don't want adversarial instructions sneaking into my RAG pipeline.”
Email-triggered agent safety check
“I have an email my agent is about to act on — can you check its body for embedded jailbreak instructions or hidden prompt injections before it executes any actions?”
MCP tool response sanitization
“My agent just got a response back from an external MCP tool server. Scan that response text for any indirect prompt injection or jailbreak attempts before I let my agent continue.”

Endpoint
POSThttps://shopify-intel.agentdiet.dev/v1/rag-poison-shield?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent ingests untrusted external content — scraped web pages, emails, MCP tool responses, or A2A payloads — and you need to detect and neutralize hidden prompt injection or jailbreak instructions before they reach your LLM. Prefer it over generic content filters when your threat model specifically involves adversarial AI prompt manipulation rather than spam or NSFW content.
Side effects
- Empty or missing 'text' field returns a 400 validation error
- Payment not provided or invalid results in HTTP 402 payment required
- Extremely large payloads may be rejected or truncated
- Ambiguous obfuscated injections may produce false negatives
- Network timeout for slow upstream processing
