# Nextcloud Talk Bot Integration
|
||||
|
||||
Inara is registered as a bot in Nextcloud Talk, receiving messages via webhook and replying through the bot API.
|
||||
Cortex connects to Nextcloud Talk as a bot — each Cortex user gets their own webhook endpoint routed to their chosen persona.
|
||||
|
||||
**Status:** Live and confirmed working (2026-03-20)

**Status:** Live and confirmed working (2026-03-20); per-user routing added 2026-03-27

|
||||
## Installation
|
||||
## Prerequisites
|
||||
|
||||
- Access to the Nextcloud server (Docker exec or SSH)
|
||||
- The Cortex server reachable at a public HTTPS URL
|
||||
- The user pre-registered in Cortex (`manage_passwords.py invite`)
|
||||
|
||||
---
|
||||
|
||||
## Per-User Setup
|
||||
|
||||
### 1. Create the user's `channels.json`
|
||||
|
||||
Create `home/{username}/channels.json` on the Cortex server:
|
||||
|
||||
```json
|
||||
{
|
||||
"nextcloud": {
|
||||
"persona": "inara",
|
||||
"url": "https://cloud.dgrzone.com",
|
||||
"bot_secret": "<a secret you choose — must match the occ install command>",
|
||||
"timeout": 55
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
- **`persona`** — which persona responds (must exist under `home/{username}/persona/`)
|
||||
- **`url`** — base URL of the Nextcloud instance
|
||||
- **`bot_secret`** — a shared HMAC secret; you choose this value and use it in both `channels.json` and the `occ` install command
|
||||
- **`timeout`** — seconds to wait for the LLM before sending a timeout message (NC Talk is async, so 55s is safe)
|
||||
|
||||
### 2. Register the bot in Nextcloud
|
||||
|
||||
Run on the Nextcloud server (inside the Docker container):
|
||||
|
||||
```bash
|
||||
docker exec -it --user www-data <nc-app-container> php /var/www/html/occ talk:bot:install \
|
||||

## Configuration
|
||||
|
||||
**`cortex/.env`:**
|
||||
```
|
||||
NEXTCLOUD_URL=https://cloud.dgrzone.com
|
||||
NEXTCLOUD_TALK_BOT_SECRET=<shared secret — must match occ install command>
|
||||
```
|
||||
|
||||
`NEXTCLOUD_URL` defaults to `https://cloud.dgrzone.com` in `config.py`.
|
||||
|
||||
**Nginx:** The `/inara-nextcloud-talk-webhook` endpoint must be reachable by Nextcloud without basic auth. Add a location block before the default `auth_basic` block:
|
||||
|
||||
```nginx
|
||||
location = /inara-nextcloud-talk-webhook {
|
||||
proxy_pass http://127.0.0.1:8000;
|
||||
proxy_set_header Host $host;
|
||||
proxy_set_header X-Real-IP $remote_addr;
|
||||
}
|
||||
```
|
||||
|
||||
(The `/channels/` prefix is already bypassed for Google Chat — consider moving the webhook path to `/channels/nextcloud` in a future cleanup to unify the nginx config.)

||||

|
||||
## How It Works
|
||||
|
||||
1. User sends a message in Talk → Nextcloud POSTs a signed webhook to `/inara-nextcloud-talk-webhook`
|
||||
2. Cortex verifies the incoming HMAC signature, extracts the message text, runs it through the LLM
|
||||
3. Cortex POSTs the reply to `/ocs/v2.php/apps/spreed/api/v1/bot/{token}/message` with its own HMAC signature
|
||||
4. The webhook handler returns HTTP 200 immediately; the LLM call happens in a `BackgroundTask` (prevents Nextcloud from disabling the bot due to slow response)

||||

## Multi-User Note
|
||||
## Nginx
|
||||
|
||||
NC Talk currently uses the **default user and persona** (`settings.default_tier`, `load_context()`). All Talk conversations go to Inara regardless of who is messaging. Per-conversation persona routing (e.g., Holly gets Tina) is a future enhancement — would require mapping Nextcloud user IDs or conversation tokens to Cortex users.
|
||||
The `/webhook/` prefix is already public in `auth_middleware.py`. If Nginx applies basic auth or IP restrictions, add a `location` block before the default auth block:
|
||||
|
||||
---
|
||||
|
||||
## Claude CLI Auth in systemd
|
||||
|
||||
The `CLAUDE_CODE_OAUTH_TOKEN` in `.env` goes stale after each `claude auth login` (tokens rotate). Cortex reads the token live from `~/.claude/.credentials.json` on every Claude call (`llm_client._fresh_claude_token()`), so no manual `.env` update is needed after re-authentication.
|
||||
|
||||
Also: never set `ANTHROPIC_API_KEY` to an OAuth token value (`sk-ant-oat01-...`) — the Claude CLI treats it as a direct API key and fails. Only real API keys (`sk-ant-api03-...`) belong in `ANTHROPIC_API_KEY`.
|
||||
```nginx
|
||||
location ^~ /webhook/ {
|
||||
proxy_pass http://127.0.0.1:8000;
|
||||
proxy_set_header Host $host;

## Triggering the Bot
|
||||
|
||||
- **@mention** — prefix the message with `@inara` (or whatever `AGENT_NAME` is set to); the prefix is stripped before sending to the LLM
|
||||
- **@mention** — prefix the message with `@{persona_name}`; the prefix is stripped before sending to the LLM
|
||||
- **Any message** in a conversation where the bot is enabled — all messages are forwarded, not just @mentions
