# TypeScript SDK

> Add AgentMuxer tools to the agent framework you already use.

Let your agent find and use tools for web research, page extraction, company enrichment, and more—all through your AgentMuxer account.

## Choose your framework

Choose a guide to build your first research agent.

## What you need

* **Node.js 22.18 or later and ESM.** See [tested runtimes and framework versions](/reference/compatibility).
* **An application key.** Create one in [Applications](https://app.agentmuxer.com/dashboard/applications). Keep it on your server as `AGENTMUXER_API_KEY`; no OAuth sign-in is needed.
* **A model-provider key.** Your existing provider runs the model and bills you separately.
* **Credits for paid tools.** The tutorials request one purchase up to \$0.10. Read [billing and approvals](/guides/billing) to choose spending limits and payment-confirmation settings.

## Other frameworks

If your framework supports remote MCP servers, [connect with MCP](/sdk/native-mcp). You don't need the AgentMuxer SDK.
