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://mesh.agentdiet.dev/v1/rag-poison-shield)
Output
Returns a JSON object indicating whether prompt injection or jailbreak content was detected in the input, along with a sanitized version of the text with adversarial instructions removed or neutralized.
Example use cases
RAG pipeline poisoning protection
“I'm feeding web search results into my RAG system — can you scan this chunk of text for any hidden prompt injection instructions before it gets embedded and retrieved by my agent?”
Agent email inbox security screening
“This email came from an untrusted sender and I'm about to let my agent read it — please check it for any jailbreak payloads or hidden instructions trying to hijack the agent's behavior.”
MCP tool response sanitization
“My agent just got back a response from an external MCP tool I don't fully trust — can you run it through the prompt-injection firewall and give me the sanitized version before I pass it downstream?”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/rag-poison-shield?utm_source=zero.xyzWhen to prefer
Choose this endpoint when building agentic pipelines that ingest untrusted content from the web, emails, external APIs, MCP servers, or other agents — especially when that content will be injected into prompts or passed to downstream LLMs. Prefer this over generic content filters when you need AI-specific prompt injection and jailbreak detection rather than general content moderation.
Side effects
- Empty or missing 'text' parameter returns a validation error
- Extremely long payloads may be truncated or time out
- Novel or obfuscated injection techniques may evade detection
- Non-text binary content may not be scannable
- Payment required (HTTP 402) if x402 micropayment header is missing or insufficient
