# OpenDQV Cloud > Write-time data quality enforcement, delivered as a managed cloud service. > OpenDQV Cloud validates each record at the moment it is written — the bouncer > at the door — so bad data is caught before it enters your systems, not > discovered in a report weeks later. OpenDQV Cloud is the managed, enterprise service in the OpenDQV family. OpenDQV is an open data-contract standard; OpenDQV Cloud runs that standard as a write-time, multi-tenant validation engine you reach over HTTPS or through MCP-compatible AI assistants. ## What it does - **Write-time validation.** Records are checked against a data contract as they are written. A failing record can be blocked (enforcement) or logged without blocking (observation) — you choose per contract. - **Data contracts.** Human-readable YAML contracts define the rules. Unlimited contracts at every tier. - **Immutable audit trail.** Every validation is recorded in a hash-chained, point-in-time-reconstructable audit log — evidence for regulated data governance. - **Reachable by AI assistants.** The service exposes an MCP surface, so an MCP-compatible assistant can ask questions like "what failed validation last week?" or "which rule is failing most?" in natural language. ## What it is not OpenDQV Cloud is data quality — deliberately just that. It is not a data catalog, lineage tool, observability platform, or master-data-management suite. It does one job well: enforcing data quality at write time. ## Getting started - Start a free 14-day trial (200 ODU, no credit card): https://app.opendqv.com - Trials and paid plans include full product access; connection details appear in your dashboard once you sign up. ## Pricing (pay-as-you-go, per ODU-hour of engine uptime) - **Trial** — free, 14 days / 200 ODU. - **Standard** — £5 / ODU-hour.
