Overview

Loki MCP Server provides a bridge between AI models and your Grafana Loki log infrastructure.

Our verdict

With a security score of 30/100, this server is classified as high-risk. This rating stems from the fact that it is a community-maintained project rather than an official Grafana offering, and it currently lacks a defined license, leaving legal usage terms unclear. Users should exercise caution regarding credentials, as authentication methods have not yet been editorially reviewed.
