StackOne provides a tool gateway that sits between AI agents and business applications, enabling assistants to read and act in HR, finance, IT, and CRM while enforcing per-person permissions. It combines an MCP gateway with 580+ connectors and 36,000+ actions, and supports MCP, A2A, SDKs, and APIs, plus an AI connector builder; it discovers and loads only the tools needed for a task and enforces security policies and audit logs. The platform differs by offering a large ecosystem of connectors and pre-built actions, strong governance and security features, and an OEM embedding option, while legacy HRIS, ATS, and CRM APIs remain available. Its goal is to help organizations deploy AI assistants across teams quickly and safely by providing a scalable, governed tool layer for AI agents.
