Get started¶
Pick the path that matches what you are building. Each one ends with working code.
| You want to | Use | Start here |
|---|---|---|
| Call models from an app or a script | The OpenAI-compatible API, with any OpenAI client | Your first API call |
| Add an assistant to your own software, with tools that act on it | The .NET or TypeScript SDK | Your first agent |
| Let every chat and agent use a system you run | An MCP server, registered on the Fadenstack server | MCP servers |
| Share instructions and procedures across teams | Skills | Skills |
Which SDK¶
| .NET SDK | TypeScript SDK | |
|---|---|---|
| Runs in | Desktop applications and add-ins on Windows, any .NET host | Browsers, browser extensions, web pages, Node |
| Targets | netstandard2.0 (.NET Framework 4.6.2 and later) and net8.0 |
ES modules with type declarations |
| Chat panel | WPF | React |
| Start | .NET SDK | TypeScript SDK |
Both SDKs share the same model: the agent runs on the device, the server governs it. Concepts explains it once for both.
