I'm confused about the new MCP

I’m currently testing activepieces and on their pricing page, they say unlimited MCP servers. But when I get inside my dashboard, I can only have one project, hence one MCP server that is connected to flows only and not pieces. I don’t understand how I can have “unlimited mcp servers”.

Do I need to have at least 1 paid flow ($5 per month) running or what? Also, what happened to linking tools?

I was aware that there was the ability to connect pieces, but now it isn’t there.

Any clarifications?
