Ollama Localhost Guardian

When to Use

• User says ollama security or task matches this capability
• User says is ollama exposed or task matches this capability
• User says secure local LLM or task matches this capability
• User says ollama localhost or task matches this capability

Workflow

1. Check listener on default Ollama port (11434) via ss or netstat.
2. Pass if bound to 127.0.0.1; warn if 0.0.0.0 or ::.
3. Optionally check OLLAMA_HOST env and systemd override files (read-only).
4. Recommend binding to 127.0.0.1; hitl-approver before config changes.
5. Note installed AI packages (mcp, openai, etc.) for inventory only.
