The three to remember
The most installed MCP, and for good reason: it eliminates hallucinated APIs.
- · Utility 9/10, best of the selection

What to know
An MCP server runs on your machine or at a vendor and exposes “tools” the agent can call. Every install adds attack surface: read the security dot and requested permissions before wiring a community server, and run mcp-scan after each addition.
