Try the demo
The demo board at demo.phpbb-mcp.com runs the extension with sample discussions, a few spam topics and spam accounts. Connect your own AI app to it and see what a member can do through MCP, without installing anything.
1. Pick a demo account
There are six shared accounts, demo1 to demo6. The password is in the welcome announcement, which is also at the top of every forum. If one account is busy or its token quota is full, take another.
The accounts are shared: everyone who uses the same account sees its private messages, tokens and connected apps, and can revoke them. Post nothing private.
2. Connect an app
The server address of the demo is:
https://demo.phpbb-mcp.com/app.php/mcp
Claude, ChatGPT and Gemini apps
Add a custom connector (remote MCP server) with that address. The app sends you to the demo board: log in with a demo account, choose what the app may do and confirm with the same password.
Only reading is ticked by default. Tick forum:write or pm:write as well if you want the app to post or send private messages.
Claude Code, Gemini CLI, Cursor and other tools
These can use the same sign-in, or a personal access token. To make a token, log in on the demo board and open User Control Panel → MCP server. The page shows ready-made snippets with the token filled in. For Claude Code it looks like this:
claude mcp add --transport http phpbb-demo https://demo.phpbb-mcp.com/app.php/mcp --header "Authorization: Bearer YOUR_TOKEN"
3. Things to ask
- “What are the newest topics on the demo board?”
- “Summarise the discussion in the support forum.”
- “Which posts look like spam, and why?”
- “Start a topic in General discussion to say hello.”
- “Send demo2 a private message, then check that it was sent.”
What the demo does not show
- Member tools only. The demo accounts can use the 15 tools for reading, writing and private messages. The moderation and anti-spam tools are off on the demo, because the accounts are shared. See Tools for everything a real board can offer.
- Weekly reset. Every Sunday at 03:00 UTC the board is wiped and set up again. Everything posted, every token and every connected app is removed.
- Shared limits. Limits count per account, so one visitor can use up an account’s writes or tokens for a while. Tokens and app connections on the demo last 7 days at most.
- No security testing. Please test only on your own board. See how to report a security problem.
