Why an AI Agent Interface?
Achieve Precision in Every API Call.
Our AI interfaces empower your AI agents to execute actions in SaaS tools with greater accuracy than leading models to more than 200 enterprise connectors.
Less time tooling & debugging.
Eliminate the complexities of fragmented APIs and unreliable community MCP servers. Leverage over 3,000 pre-configured AI actions via StackOne's Toolset - no setup or maintenance needed.
Improve your product.
Using StackOne pre-mapped authentication & tools frees your engineering team to elevate your AI agents with best-in-class domain knowledge instead of focusing on tool declarations.
“”
We’ve been impressed by how quickly and deeply StackOne integrates with complex enterprise systems - and now, with their focus on agent-to-agent interoperability, they’re unlocking even more powerful use cases for customers.

04

Pre-Built Authentication UI.

StackOne auto-detects and handles all authentication types via our embeddable Hub, clearing the path for your agents so they can focus on taking action without interruption while  simplifying each tool call.

Pre‑written instructions for all integrations mean faster onboarding and fewer “How do I connect?” emails - plus the freedom to swap in your own guides anytime.

StackOne simplifies multi-tenant tool call authentication using account identifiers, improving accuracy and reducing credential errors. The dashboard lets you control AI actions per project or tenant for fine-grained access with minimal effort.

This component will only work on the published/exported site. Full documentation in Finsweet's Attributes docs.
07

Open Source

StackOne is built with open-source at its core, from our use of Instructor or Langchain to Zod, Vllm, SSTand more. That's why we're also commited to support and develop open-source projects to empower AI agent builders everywhere.

Crossroad
Crossroad enables AI agents to perform agentic tasks using Cloudflare Durable Objects. This lightweight framework allows for scalable execution of tool calls, leveraging Cloudflare Workers for efficient processing. Explore Crossroad on GitHub.
Open API Tool Generation
StackOne's stackone-ai-node SDK includes toolsets like OpenAPIToolSet for creating tools out of OpenAPI specifications
