How do I remediate mcp-teamviewer if I installed it?

Remove mcp-teamviewer from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

I already installed mcp-teamviewer — how do I know if it already compromised me?
