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://shopify-intel.agentdiet.dev/v1/tool-poisoning-shield)
Output
Returns a sanitized version of the input text with prompt injection and jailbreak payloads identified and removed, along with detection metadata indicating whether malicious content was found.
Example use cases
Screening web-scraped content for agent pipeline
“I'm about to feed this scraped article into my AI agent — can you scan it for hidden prompt injection instructions first and return the cleaned text?”
Validating MCP tool response before execution
“Before my agent acts on this MCP tool response, check it for any embedded adversarial instructions or jailbreak payloads that could hijack its behavior.”
Filtering untrusted email before AI summarization
“I want my AI to summarize this customer email, but first scan it for any hidden prompt injection attacks that could manipulate the agent.”

Endpoint
GEThttps://shopify-intel.agentdiet.dev/v1/tool-poisoning-shield?utm_source=zero.xyzWhen to prefer
Use this endpoint when your AI agent is about to consume content from untrusted external sources — web pages, emails, third-party API responses, MCP tool outputs, or A2A payloads — and you need to screen for hidden prompt injection or jailbreak instructions before processing. Prefer this over manual content filtering when operating in multi-agent or agentic pipeline contexts where indirect prompt injection is a real attack vector.
Side effects
- Empty or missing 'text' parameter returns validation error
- Text too long may exceed processing limits
- Novel or highly obfuscated injection patterns may evade detection
- Payment failure via x402 returns 402 with payment details
- Service unavailability returns 5xx error
