What it does

StackOne is a tool gateway for AI agents. It offers 590+ pre-built connectors and 36,000+ actions covering systems such as Zendesk, Gmail, and Salesforce, and handles managed authentication so agents can act in those tools.

Agents can reach connectors through MCP, A2A, an AI Action SDK, or a REST API. Teams set up a connector profile in the dashboard, choose which actions and events an agent may use, link an account, and test actions in the Playground. Security features include prompt-injection defense, tool policies, and an AI Connector Builder for custom connectors.

The platform fits developers and enterprise teams building internal agents, and SaaS product teams embedding integrations for their own customers. Gateway and OEM plans each have a free starter tier; Team costs $600 per month and Enterprise is sold through sales.
