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/workflows/rag-context-sanitizer)
Output
Returns a sanitized version of the input text with any detected prompt injection payloads or jailbreak instructions neutralized or flagged, making it safe to pass into an AI agent's context window or RAG pipeline.
Example use cases
RAG pipeline content sanitization
“I'm about to feed these 10 web page excerpts into my RAG pipeline — can you scan each one for hidden prompt injections and only pass me the sanitized text so my agent doesn't get hijacked?”
Email-based agent attack prevention
“This email came in from an unknown sender and my agent is about to read it — please scan the full email body for any embedded jailbreak or prompt injection attempts before my agent processes it.”
MCP tool response safety check
“My agent just got back a response from an external MCP tool and I want to make sure it's safe — can you run it through the prompt-injection firewall and tell me if anything suspicious was found or removed?”
Technical details
Endpoint
POSThttps://shopify-intel.agentdiet.dev/v1/workflows/rag-context-sanitizer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent must consume content from untrusted external sources — scraped web pages, third-party emails, external MCP tool responses, or A2A agent payloads — before using them as RAG context or passing them downstream. It is specifically designed for agent-to-agent and human-to-agent pipeline security, not generic content moderation.
Side effects
- Empty or missing 'text' field returns a 400 validation error
- Extremely large payloads may time out or be rejected
- Highly obfuscated injections using novel encoding may evade detection
- Service unavailability returns 5xx errors; use the Idempotency-Key header to safely retry
- Non-text binary content or non-UTF-8 encoded input may cause parsing failures
