add observability to the server

[aadeexyz]

yo,

i built mcpscout, a tiny sdk that tracks:

• which MCP tools were called
• how long they ran for
• why the LLM chose to call them
• and much more

zero code refactor needed. add two lines and it starts capturing events:

import { MCPScout } from "mcpscout";
new MCPScout("pk_xxx").track(mcpServer);

lmk if that sounds useful and i'll open a pr.
