# Beeper

Channel integration for eve. Matrix rooms and bridged messaging networks through Beeper.

## Install

Add this Chat SDK channel from eve's registry. This writes `agent/channels/beeper.ts` and installs Chat SDK and its adapter dependencies:

```bash
eve add channel/chat-sdk-beeper
```

## Quick start

Create `agent/channels/matrix.ts`:

```ts
// agent/channels/matrix.ts
import { createMatrixAdapter } from "@beeper/chat-adapter-matrix";
import { createMemoryState } from "@chat-adapter/state-memory";
import type { Message, Thread } from "chat";
import { chatSdkChannel } from "eve/channels/chat-sdk";

export const { bot, channel, send } = chatSdkChannel({
  userName: "My Agent",
  adapters: {
    matrix: createMatrixAdapter(),
  },
  state: createMemoryState(),
});

bot.onNewMention(async (thread: Thread, message: Message) => {
  await thread.subscribe();
  await send(message.text, { thread });
});

bot.onSubscribedMessage(async (thread: Thread, message: Message) => {
  await send(message.text, { thread });
});

await bot.initialize();

export default channel;
```

See the [Beeper Matrix adapter documentation](https://chat-sdk.dev/adapters/vendor-official/matrix) for all supported events and credentials.

## Configure

Set the Matrix homeserver, access token, and bot identity environment variables documented by Beeper. This adapter consumes Matrix sync rather than webhooks, so call `bot.initialize()` and run eve in a long-lived Node.js process. It requires Node.js 22 or newer and a durable state adapter in production. See the [Chat SDK channel docs](/docs/channels/chat-sdk) for eve session dispatch, state, streaming, and human-in-the-loop behavior.
