Verify that local LLM services, including Ollama, are bound and configured safely before they are exposed or connected. Use for: Ollama security, check exposed Ollama, secure local LLM, Ollama localhost.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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. ## Integrations - `defensive-mcp-audit` - `exposed-service-triage` - `hitl-approver` ## Error Handling | Failure | Response | |---------|----------| | Ollama not running | Report not listening; no install assumed. | ## Gotchas - Check-only; config edits require user approval. ## Safety & Ethics (Publication-Ready) This skill is designed for public distribution. Constraints: - Read-only checks; no model pulling or inference API abuse. - No exposure of API keys or model weights. ### Prohibited actions …

How to install
mdr add stijnman/grok-custom-skills/ollama-localhost-guardian@sha256:13cfee16c11aaf93The line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
