Why four scores instead of one

Nearly nine in ten tools here ship an official MCP server, so “has MCP” no longer tells you anything. What separates them is how deep the write access goes, what you have to pay before an agent can act, whether it can authenticate without a human, and who is maintaining it. Every listing scores those four out of five, and shows the working.
