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://agentdiet.dev/v1/injection-guard)
Output
Returns sanitized text with hidden prompt injections and jailbreak attempts removed or flagged, along with detection metadata indicating whether threats were found.
Example use cases
Protecting agent from malicious web content
“I'm about to feed this web page's text into my AI pipeline — can you scan it for any hidden prompt injection attacks or jailbreak instructions first and return the safe, cleaned version?”
Sanitizing email before LLM processing
“Check this email body for any embedded prompt injection attempts or sneaky instructions trying to hijack my AI agent before I let it summarize or act on the content.”
Validating MCP tool response safety
“My agent just got back a response from an MCP tool I don't fully trust — can you run it through the injection guard to make sure there's nothing in there trying to manipulate my agent's next actions?”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/injection-guard?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs to process content from untrusted external sources (web scraping, emails, third-party APIs, MCP responses, or A2A messages) before passing that content to an LLM. It is especially valuable in agentic pipelines where indirect prompt injection is a real attack vector and you need a lightweight, cheap ($0.005/call) pre-processing firewall step.
Side effects
- Empty or missing 'text' query parameter returns an error
- Extremely long payloads may be truncated or rejected
- Novel or obfuscated injection patterns may evade detection
- Non-text binary content is not supported
- Rate limiting may occur under high request volume
