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://token-intel.agentdiet.dev/v1/rag-poison-shield)
Output
Returns a structured JSON object containing the scan result for the submitted text, indicating whether prompt injection or jailbreak payloads were detected and providing a sanitized version of the input text safe for downstream LLM consumption.
Example use cases
RAG pipeline safety check
“Before indexing this web page I just scraped, scan the full text for any hidden prompt injections that could poison my RAG knowledge base — here's the HTML content.”
Email agent inbox protection
“My agent is about to read and act on this incoming email — can you first check the email body for any embedded jailbreak instructions or indirect prompt injection attempts?”
MCP tool response sanitization
“I got this response back from an external MCP tool and I want to make sure it's safe before my agent acts on it — scan it for hidden prompt injections or jailbreak payloads.”
Technical details
Endpoint
GEThttps://token-intel.agentdiet.dev/v1/rag-poison-shield?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent pipeline ingests content from untrusted external sources — such as scraped web pages, third-party API responses, MCP tool outputs, or user-submitted emails — and you need to sanitize that content before passing it to an LLM. It is particularly valuable in RAG architectures, A2A agent networks, and any workflow where indirect prompt injection is a security concern.
Side effects
- Empty or missing 'text' parameter returns a validation error
- Extremely long payloads may be truncated or rejected
- Service unavailable if payment (x402) is not resolved
- False negatives possible for novel or obfuscated injection techniques
- Non-UTF-8 or malformed HTML may cause parsing errors
