The AI Playground lets you test any action from your linked accounts using natural language.
Playground Main Interface
Testing tool, not a production agent. The Playground is designed for quickly testing actions and exploring capabilities. For production use cases, build your own agent using our MCP Server, AI Toolset, or A2A Protocol. See Agent Protocols Comparison for guidance.
Access Required: Contact StackOne support if you don’t see the Playground in your dashboard.

Example Queries

The queries you can run depend on which accounts you’ve connected and what actions are available. Tailor your prompts to your agent’s use case:
