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://company-enrich.agentdiet.dev/v1/rag-poison-shield)
Output
Returns a sanitized version of the submitted text with prompt injection and jailbreak payloads identified and removed or flagged, along with detection metadata indicating whether any malicious instructions were found.
Example use cases
RAG pipeline injection guard
“I'm pulling documents from external websites into my RAG pipeline — can you scan this HTML page content for any hidden prompt injections or jailbreak instructions before I feed it to the LLM?”
Email body jailbreak check
“I just received an email from an unknown sender and I want to pass its body to my AI assistant — can you first check this email text for any embedded prompt injection or jailbreak attempts?”
MCP tool response sanitization
“My agent just got back a response from an external MCP tool and I'm not sure I trust it — can you scan this tool output for hidden instructions or prompt manipulation before I let my agent act on it?”
Technical details
Endpoint
GEThttps://company-enrich.agentdiet.dev/v1/rag-poison-shield?utm_source=zero.xyzWhen to prefer
Use this endpoint whenever an AI agent or pipeline is about to process text from an untrusted external source — scraped web pages, third-party emails, MCP tool responses, A2A agent payloads, or RAG document chunks — especially when those inputs will be passed directly to an LLM. Prefer this over manual inspection when operating autonomous agent swarms that consume external data at scale.
Side effects
- Empty or missing 'text' parameter returns a validation error
- Extremely long payloads may be truncated or rejected
- Sophisticated obfuscated injections may evade detection
- Service may return 402 Payment Required if payment credentials are not provided
- Non-text binary content may not be parseable
