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://whale-momentum.agentdiet.dev/v1/injection-firewall)
Output
Returns a sanitized version of the input text with any detected prompt injection or jailbreak payloads removed or flagged, along with detection metadata indicating whether malicious content was found.
Example use cases
Secure web scraping for agent pipelines
“I'm about to feed this scraped webpage into my AI summarizer — can you scan it for hidden prompt injections or jailbreak instructions first before the model sees it? Here's the raw HTML.”
Email safety check before AI processing
“My agent is reading incoming emails automatically. Can you screen this email body for any embedded prompt injection attacks or instructions trying to hijack my AI before it acts on the message?”
MCP tool response validation
“My agent just got a response back from an external MCP tool and I don't fully trust it. Can you check that payload for hidden jailbreak or prompt injection content before I let my agent continue?”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/injection-firewall?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent is consuming text from untrusted external sources — scraped web pages, incoming emails, third-party MCP tool responses, or A2A agent payloads — and you need a dedicated security layer to detect and strip hidden prompt injection or jailbreak instructions before they reach your model. Prefer this over general-purpose content filters when the specific threat model is adversarial LLM prompt manipulation.
Side effects
- Empty or missing 'text' parameter returns a validation error
- Extremely long payloads may be truncated or timeout
- False negatives are possible for novel or obfuscated injection techniques
- Ambiguous borderline content may not be flagged
- Payment failure via x402 will block the request
