Control what your AI agent can do.
A checkpoint on every action your agent takes.

Your agent doesn’t reach the outside world directly — it goes through VENZX first. Before every tool call, VENZX decides: allow it, block it, pause it for a human, or stop because the run hit its spend cap — and keeps a tamper-evident record of every decision, so you can prove exactly what your AI did. Works with any agent, framework, or MCP server. Pay only for what you check.

Job 1

Controls actions.

Your agent goes through VENZX before it touches the outside world. You decide which tools run freely, which pause for a human, and a hard spend cap — and VENZX enforces it on every call, before anything happens.

Allow or block any tool

Your agent can send email, call APIs, run code, move money. You decide which tools it’s allowed to use — VENZX checks every call before it runs and refuses anything that isn’t on the list.

  • Per-tool allow / deny, enforced on every single call
  • Dangerous destinations (internal IPs, cloud metadata) blocked automatically
  • Decided in milliseconds, before the action ever happens

Pause for a human

High-risk actions — send, pay, delete — shouldn’t run on their own. Mark them and VENZX returns “needs review”, pauses the agent, and pings you so a person approves before anything happens.

  • Mark any tool as approval-required
  • The agent halts until a human says yes — no silent sends
  • Approve from your own flow: a Slack prompt, a dashboard, an email link

Cap the spend

Agents loop. A runaway loop can burn your budget in minutes. VENZX enforces a hard ceiling on calls and cost per run, so the agent stops itself before that happens.

  • Per-run limits on tool calls, tokens, and cost
  • Enforced across every server, not just one process
  • The circuit breaker your agent doesn’t have on its own
Job 2

Keeps proof.

Every decision is written to a record where each line is linked to the one before it. If anyone alters a single line, the record shows it — so you can prove, any time, exactly what your AI did.

A record that can’t be faked

Every check VENZX makes is written to a log where each line is linked to the one before it. Change, remove, or reorder a single line and the link breaks — so the record can’t be quietly edited later.

  • Each line cryptographically chained to the previous one
  • A built-in check points straight to any altered line
  • Written safely to disk so nothing is lost

Proof you can show

When someone asks “can you prove your AI is safe?”, the answer is already waiting. Download the record any time and hand it to your boss, a customer, or an auditor.

  • Download as a simple file whenever you need it
  • Every entry says what happened, when, and why
  • Useful as supporting evidence in security reviews

Clear reasons, every time

Nothing is a mystery. Every decision says exactly why — “tool blocked”, “needs approval”, “over budget” — so you always know what happened and why.

  • A plain reason on every allow / block / approval
  • The exact tool and arguments, on the record
  • No black-box scores or guessing
