Line CLI takes a long time to start

TroubleshootingUpdated November 2, 2026

Line itself starts quickly. Delays usually come from:

MCP servers that are slow to start (for example ones installed with npx on first run). Check with line mcp.
Plugins with slow session_start hooks.
A very large project folder: start Line in the project root, not your whole home folder.

Disable what you don't need and try again.
