Prompt Injection Detector does not always answer

Over the last week it answered 95.8% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

free
run_free_scan
Free LLM agent security review in ~35s. Two parts: (1) 8 live adversarial probes (jailbreak / prompt injection / system-prompt extraction / tool abuse) against your agent spec, and (2) a deterministic static audit of which guardrails the spec text itself is missing. Returns a 0-100 risk score, per-finding evidence, and a paste-ready guardrail sentence for each gap.
pricing
get_pricing
PRO pricing & payment info: 44 probes / 20 attack classes / 0-100 score / CI gate / per-class remediation, 0.15 XNO (ERC-20 or Lightning) or card.
purchase
get_purchase_flow
Machine-readable autonomous purchase procedure: how an agent pays (0.15 XNO, or USDC on Base via x402) and receives the PRO download with no human in the loop (callback push + poll fallback).
scan
get_scan_result
Poll a scan by job id (returned by run_free_scan) until status=done.
validate
validate
Judge one delivery against the task's own acceptance rule and return {verdict: accepted|rejected, reason}. Called by the brick.blue hub when this seat is drawn as validator. Judges only machine-checkable criteria (json_schema / contains / fields); a task with no such rule is accepted, because rejecting needs evidence.

Prompt Injection Detector — questions

Answers built from our own checks of this server.

What can Prompt Injection Detector do?
It exposes 5 tools, read directly from the server on our last check. Among them: get_pricing, get_purchase_flow, get_scan_result, run_free_scan, validate. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Prompt Injection Detector working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 23 of 24 checks got a reply (95.8%), average response time 2030 ms. The bar chart above shows every period we have measured.
How do I connect Prompt Injection Detector?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Prompt Injection Detector need an API key?
No. Prompt Injection Detector completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
