# Built-in integrations

> What ships with Luno OS today and what's coming.

> [!NOTE]
>
> Managed integrations (Luno-hosted OAuth for apps like Google Workspace, GitHub, or Notion) are being rebuilt on [Nango](https://nango.dev) and are coming soon. Until then, connect any API with [custom integrations](https://docs.os.meetluno.ai/learn/credentials/custom-integrations.md).

## What works today

| Integration | What it does |
| - | - |
| **Slack** | Talk to agents from Slack channels and DMs. Install the Luno OS Slack App or your own Slack app. See [external channels](https://docs.os.meetluno.ai/learn/agents/external-channels.md). |
| **Web search** | Agents get the built-in `web_search` and `web_fetch` tools. No setup needed on Luno OS cloud; self-hosted runtimes set `EXA_API_KEY`. |
| **Custom credentials** | Store API keys and OAuth apps in the credential vault and call any API from a `defineAction`. See [custom integrations](https://docs.os.meetluno.ai/learn/credentials/custom-integrations.md). |
| **MCP servers** | Attach tools from any MCP server to an agent. |

## Next steps

> **[Custom apps and MCP](https://docs.os.meetluno.ai/learn/credentials/custom-integrations.md)**
>
> Register connectable apps and author them with `defineIntegration`.

> **[Using credentials in code](https://docs.os.meetluno.ai/learn/credentials/use-credentials.md)**
>
> Resolve credentials inside your actions at runtime.
