No dedicated test fixture simulates a mid-session server crash/disconnect #2437

Description

@CloneOfAlex

Which client?

All / shared core

The problem

core/mcp/inspectorClient.ts has substantial crash-reconciliation logic (roughly lines 1207-1260 and 1965-2160) for handling a server process dying or disconnecting mid-session, but there's no dedicated test fixture/mock server that deliberately crashes at a chosen point in a session. Coverage of this logic currently relies on incidental paths rather than a targeted simulation, so a regression here could slip through.

Solution you have in mind (optional)

Add a test-servers fixture (or a mode flag on an existing one) that can be told to crash/hang at a specific point in a session, and add core tests that drive the client through the reconciliation paths using it.

  • I searched existing issues and this is not a duplicate.
  • This is a request for the Inspector itself, not for the MCP specification or an SDK.
