Agent SDK

Bring StackOne actions into your code as typed TypeScript and Python tools. Fetch the tools for a linked account, filter them to what your agent needs, and hand them to your framework’s function-calling loop. The SDK is available in two languages:

How the StackOne Agent SDK works

Your agent connects to StackOne, which handles authentication and data normalization for hundreds of SaaS providers like Salesforce, Workday, Slack, and more.

Component	Description
Your Agent	Built with LangChain, CrewAI, OpenAI, Vercel AI, or any framework
StackOne	AI Integration Gateway: handles authentication, transforms data, manages connections
SaaS Providers	Salesforce, Workday, Greenhouse, Slack, Gmail, HubSpot, and hundreds more

Key concepts:

• Initialize a ToolSet: Create a StackOneToolSet instance to access tools for providers like Workday, Greenhouse, Slack, and more
• Filter Tools: Use provider glob patterns like workday_* and slack_*, or the fetch_tools() method for provider/action/account filters
• Execute Tools: Call provider APIs through StackOne tool interfaces: list employees, send messages, create tickets
• Tool Discovery: Discover relevant tools at runtime via natural language queries
• Multi-Tenant: Each tool execution requires an account_id to identify which customer’s account to access

Calling actions

Before starting you need to have followed the previous setup steps described in the Getting Started. Then pick your framework — each guide is a complete agent loop, from install to handing StackOne tools to your model:
