Hey, thanks for the report. This is a known issue with the CLI agent, and the team is aware of it and tracking it.

A couple things to try:

  1. Temporarily disable MCP servers

The CLI agent loads the MCP config from the same files as the IDE, and a stuck MCP server can block startup completely. Try renaming the config to rule this out:

mv ~/.cursor/mcp.json ~/.cursor/mcp.json.bak

If you also have a project .cursor/mcp.json, rename that too. Then run agent again.

  1. Share your cursor-agent version
agent --version

If it works without MCP, that helps narrow it down. If it still hangs, we can dig in further.

Also, there’s a known interaction between iTerm2 and the CLI on macOS Apple Silicon. If disabling MCP doesn’t help, try running agent from the standard Terminal.app and see if anything changes.

Let me know how it goes.
