A tool connection is the start of the workflow
A shared tool interface can help applications connect. The useful work still depends on the right records, clear permissions and reliable handling of the next action.
What MCP improves
A common interface can make tools easier for an application to discover and call. Verify the operations and permissions each connection actually exposes.
What it does not replace
It does not remove the need for role-aware access, workflow-specific policies, or custom business logic around side effects.
What operators still need
Operators still need a clear action history, a way to handle a failed request and a test before changes reach users.
