What

Claude Code now releases an MCP server's ownership lease (a claim on managing that server's registration) using a backoff pattern with an 8000ms gap and a 60000ms cap, rather than releasing it immediately when certain events occur.

Why

Pacing how quickly ownership of an MCP server registration can be released and reclaimed likely helps avoid rapid churn or conflicts when multiple processes are involved.
