Feishu's official MCP causes a memory leak: tracking down orphan processes from lark-mcp
Mac memory mysteriously eaten up, and it turns out dozens of orphan node processes were left behind by Feishu's official lark-mcp. The root cause is that its stdio lifecycle only handles data inflow, not pipe closure, so the process doesn't kill itself after the host exits. Upstream issues and PRs were filed but have just sat there unmerged, and the repo hasn't been updated for over a year.
