What
MCP servers are add-ons that give Claude extra tools through the Model Context Protocol. Some of their tools run tasks in the background. When such a task finishes, Claude Code queues a notification so Claude sees the result. That notification now names the server and the tool that ran the task.
This happens in all three places these notifications are queued:
the normal path
a fallback ("degraded") path
replaying notifications when a session is resumed
Why
A finished background MCP task now counts as a use of that MCP tool, so Claude Code's tracking of which tools have been used includes it.
