LABSCO SUMMARY
Moderate the forum by asking.
Running a forum is mostly small repetitive actions spread across categories, topics, users and groups. Having all of them in one place turns a session in the admin panel into a conversation.
What it is
An MCP server for Website Toolbox forums, covering the forum's objects end to end: categories and their per-group permissions, topics and posts, users and the groups they belong to, private conversations and their messages, and moderators.
What you get
- Categories listed, created, updated and deleted, with user-group permissions read and changed
- Topics created with an initial post, updated, listed and deleted
- Posts created as replies, edited, listed and removed
- Forum users created, updated, read and deleted
- Users made to follow or unfollow specific topics
- User groups created with permissions, and members added or removed
- Private conversations started, and their messages listed, read and sent
- Moderators listed and read
Requirements
A forum API key from Integrate → API in the Website Toolbox admin area, set as WEBSITETOOLBOX_API_KEY. Node.js 18 or newer for the npm package, or install the .mcpb bundle into Claude Desktop and paste the key when prompted. A forum username and email address can optionally be supplied so the calls act as that specific member.
Setup effort
One command plus a key — npx websitetoolbox-mcp, then supply credentials
