Let AI assistants work on your phpBB board, as a real member

phpBB MCP Server is a phpBB 3.3 extension that turns your board into a remote Model Context Protocol server. Claude, ChatGPT, Gemini and other AI clients sign in as a forum member and can only do what that member may already do.

Acts as a real member

Every request runs as one forum account and is checked against its live phpBB permissions. The AI cannot read a forum, post or moderate where that member cannot.

Built for moderation and anti-spam

Moderators can review the queue, read reports, look at an account’s history and act on spam: soft delete, ban or purge a spammer, always after a preview they confirm.

Checked and logged

Everything is off by default. Tools need their own permissions and token scopes, calls are rate limited, and tool calls are recorded in an audit log.

What members and moderators can ask

Members

“Summarise the new topics in the support forum since Monday.” “Find the thread where someone explained the cron setup.” “Reply to my topic with the corrected config.” “Do I have unread private messages?”

Moderators

“What is waiting in the moderation queue?” “Does this new account look like a spammer?” “Soft delete these five posts and close the reports.” “Purge this spam account.”

Works with the apps people use

The Claude, ChatGPT and Gemini apps connect with a built-in OAuth sign-in: the member adds the board’s address as a custom connector, logs in on the board and picks what the app may do. Claude Code, Gemini CLI, Cursor and other tools can use the same sign-in or a personal access token from the User Control Panel.
