This analysis dismisses MCP by focusing too narrowly on local file system interactions. The real value isn't just running scripts; it's interoperability.
MCP allows any client (Claude, Cursor, IDEs) to dynamically discover and interact with any resource (Postgres, Slack) without custom glue code. Comparing it to local scripts is like calling USB a fad because parallel ports worked for printers. The power is standardization: write once, support every AI client.
Edit:
To address the security concerns below: MCP is just the wire protocol like TCP or HTTP. We don't expect TCP to natively handle RBAC or prevent data exfil. That is the job of the application/server implementation.
