Questions

-

Why charge for AI queries?
LLMs and APIs cost money to run. The free tier covers casual utility use.

+

Why charge for services?
News, video search, chat, and email all rely on APIs and infrastructure that cost money to run. The free quota covers casual daily use.

Do credits expire?
No. Once you top up, your credits are yours until you use them.

Why no unlimited subscription?
Unlimited tiers incentivize us to maximize your engagement. Pay-as-you-go keeps incentives aligned: we want efficient tools, not sticky products.

-

Is watching videos free?
Yes. We only charge when we add value (search, summaries), not for things YouTube already provides.

`) +

Is watching videos free?

Can AI agents use Mu?
Yes. Mu supports the Model Context Protocol (MCP). See the MCP page for setup and available tools.

-Like SMTP, the XMPP server: -- Runs in separate goroutines -- Listens on dedicated ports (5222 for C2S, 5269 for S2S) -- Integrates with Mu's authentication system -- Provides complete autonomy and federation -- Stores messages persistently -- Handles both inbound and outbound connections - -## Status Monitoring - -The XMPP server status is visible on the `/status` page: - -```json -{ - "services": [ - { - "name": "XMPP Server", - "status": true, - "details": { - "domain": "chat.yourdomain.com", -

-### Production Recommendations - -1. **Enable TLS**: Always use TLS in production - ```bash - export XMPP_CERT_FILE=/path/to/cert.pem - export XMPP_KEY_FILE=/path/to/key.pem - ``` - -2. **Firewall Configuration**: - - Open port 5222 for clients - - Open port 5269 for S2S federation - - Use fail2ban for brute-force protection - -3. **DNS Security**: - - Use DNSSEC for SRV records - - Verify certificate matches domain - -4. **Rate Limiting**: - - Implement connection limits (planned) - - Message rate limits (planned) - -5. **Monitoring**: - - Track failed authentication attempts - - Monitor S2S connection failures - - Log suspicious activity - -## Testing - -### Test with Real XMPP Client - -1. **Configure your client:** - ``` - JID: youruser@yourdomain.com - Password: your_mu_password - Server: yourdomain.com - Port: 5222 - Require TLS: Yes - ``` - -2. **Test local messaging:** - - Create two accounts on your Mu instance - - Connect with two clients - - Send messages between them - -3. **Test federation:** - - Find a friend on another XMPP server - - Add them: `friend@other-server.com` - - Send a message - -4. **Test offline messages:** - - Send message to offline user - - Have them login later - - Message should be delivered - -### Example with Conversations (Android) - -``` -1. Install Conversations from F-Droid or Google Play -2. Create account with existing JID -3. Enter: username@yourdomain.com -4. Enter: your password -5. Connect -6. Start chatting! -``` - -## Example Use Cases - -### 1. Self-Hosted Team Chat -Replace Slack/Discord with your own XMPP server: -- Private, self-hosted -- Full control over data -- No vendor lock-in -- Standards-based - -### 2. Federated Communities -Connect multiple Mu instances: -- Each organization runs their own server -- Users chat across organizations -- No central authority -- Distributed architecture - -### 3. Mobile Messaging -Use native XMPP clients: -- Push notifications -- End-to-end encryption (OMEMO) -- Low battery impact -- Mature mobile apps - -### 4.

FAQ

+ +
+ +

Is Mu free to use?
+ Yes! Create an account and start using Mu immediately at no cost.

+ +
+ +

Can I self-host Mu?
+ Absolutely. Mu is open source and runs as a single Go binary. Check GitHub for install instructions.

+ +
+ +

What about pricing?
+ Mu is free with 10 credits/day. Need more? Top up and pay as you go from 1p per query. No subscriptions, no tricks. See our plans for details.

+ +
+ +

How is this different from big tech platforms?
+ No ads, no algorithmic feeds, no data mining. Just simple, useful tools that work for you.

+ +
+ +

Can AI agents use Mu?
+ Yes. Mu supports the Model Context Protocol (MCP). Agents can read news, search videos, send mail, query markets, and manage their own wallet credits. See the MCP page for setup.
