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://github-audit.agentdiet.dev/v1/jailbreak-scan)
Output
Returns a structured object indicating whether prompt injection or jailbreak content was detected in the submitted text, along with sanitized/cleaned version of the input safe for downstream agent consumption.
Example use cases
Screening scraped web content before LLM processing
“I'm about to feed this article I scraped from the web into my agent pipeline — can you first scan the full text for any hidden prompt injections or jailbreak payloads before I pass it along?”
Protecting agent from malicious email content
“I received this email that my agent is going to summarize — please run it through the prompt-injection firewall first to make sure there are no adversarial instructions hidden inside it.”
Validating MCP tool responses in an agent swarm
“This MCP server just returned a response to my agent — can you check it for indirect prompt injection attacks or jailbreak attempts before my agent acts on it?”
Technical details
Endpoint
GEThttps://github-audit.agentdiet.dev/v1/jailbreak-scan?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent pipeline ingests untrusted external content — scraped web pages, emails, third-party API responses, MCP tool outputs, or A2A payloads — before passing that content to an LLM for reasoning. It is especially valuable in multi-agent architectures where one agent's output becomes another's input, creating indirect injection risk. Prefer this over generic content filters when you specifically need prompt-injection and jailbreak detection tailored to LLM/agent attack surfaces.
Side effects
- Empty or missing 'text' parameter returns a 400 validation error
- Extremely long payloads may hit size limits or time out
- False negatives: novel or obfuscated injection techniques may not be detected
- False positives: legitimate instructional text may be flagged as injections
- Service unavailability or payment failure (HTTP 402) if USDC balance is insufficient
