Let AI act on production —
without the risk.
PlanVault is the governed layer between your AI and your APIs. It runs in your own cloud, keeps secrets out of the model, and records every action — so you can say yes to AI without betting the business.
plan "refund_and_notify" order = get_order(id) issue_refund(order, amount) notify_customer(order)
The moment AI can touch production,
three things keep you up at night.
AI acts with no guardrails
An agent issues a refund — or a payment — it never should have.
Secrets leak into prompts
Your API keys end up inside an LLM prompt, logged and exposed.
No trail when it breaks
Something fails at 2am and nobody can prove what the AI did.
The controls AI doesn't ship with.
Not another model or framework — the governed layer that decides what your AI is actually allowed to do.
Risky actions wait for a human
You decide which calls need sign-off. PlanVault pauses them before money moves — the model cannot skip the gate.
Secrets never reach the model
Credentials are injected at runtime and referenced by name. The LLM sees variables — never plaintext keys.
Every action recorded & replayable
A full, event-sourced audit trail of every decision and call — ready for compliance review or post-incident replay.
You set the rules, per tool
Allow or deny each operation, flag which actions need sign-off, and cap amounts and rates — fine-grained policy the model can't override.
Scale to thousands of tools
PlanVault shortlists the relevant tools before each call — less context, lower cost, fewer wrong-tool mistakes.
Built to survive the messy middle.
AI runs fail in ways ordinary code never did — loops, crashes, lost state. PlanVault makes execution durable, observable and recoverable, so a flaky agent doesn't become a flaky product.
Crash-safe replay
Event-sourced runs resume deterministically from the last good step — a crash never loses progress or repeats a side effect.
Loop & recursion guards
Runaway loops, infinite recursion and budget blow-ups are detected and halted before they spiral.
Durable state
Every run's state lives outside the model, so nothing is lost between steps, retries or restarts.
Transparent execution
Watch each step live and inspect exactly what ran, in what order, with which inputs and outputs.
Nothing leaves your perimeter.
Watch a risky action stop for a human.
A live mock of a governed run. The agent wants to issue a $12,450 refund — PlanVault holds it until you decide.
Migrate in weeks, not quarters.
Govern what you already run. PlanVault wraps your existing REST/OpenAPI endpoints, MCP servers, webhooks and knowledge bases — no rip-and-replace, no rewrite.
Say yes to AI — and keep your name off the incident report.
