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/prompt-firewall)
Output
Returns a structured object containing the sanitized version of the input text with prompt injection and jailbreak content removed or flagged, along with detection metadata indicating whether malicious content was found.
Example use cases
Web scraping safety filter for agent
“I'm having my agent scrape product pages to summarize competitor pricing, but I'm worried the pages might contain hidden prompt injection attacks. Can you scan this HTML from their site and return a clean version my agent can safely process?”
MCP tool response verification
“My agent just got back a response from an external MCP tool and I want to make sure it doesn't contain any hidden instructions trying to hijack the agent's behavior. Can you check this payload for prompt injection before I let the agent act on it?”
Email content sanitization before LLM summarization
“I need to summarize this batch of customer emails with my AI assistant, but some might contain jailbreak attempts. Can you scan this email body for hidden prompt injections and return the sanitized text I can safely hand off?”
Technical details
Endpoint
GEThttps://company-enrich.agentdiet.dev/v1/prompt-firewall?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent is processing content from untrusted external sources — web pages, emails, MCP tool responses, or A2A payloads — and you need a dedicated security filter to detect and remove hidden prompt injection or jailbreak attempts before that content influences agent behavior. Prefer this over generic content filters when operating in agentic pipelines where indirect prompt injection is a specific threat vector.
Side effects
- Empty or missing 'text' parameter returns a 400 validation error
- Very large payloads may time out or be truncated
- Highly obfuscated or novel injection techniques may not be detected
- Payment failure via x402 returns HTTP 402 with payment required details
- False positives may sanitize legitimate content that resembles injection patterns
