Which MCP servers do people really use every day?
There are thousands of MCP servers listed now. Which ones do people actually keep running after the first week?
The ones that stay are boring: file access, git, web fetch, and something for memory. They map to work you do every day, so they keep getting called.
Servers tied to one service (a specific database, a specific SaaS) stay only if you use that service daily. Install them per project rather than globally.
A useful habit: after a week, check which tools the model actually called. Anything unused is just noise in the tool list.
On AgentAlley each listing shows the full source, so you can see exactly what a server exposes before you add it.
