A local MCP server that connects an AI coding agent to Grafana Loki, a system for collecting and searching application logs. It runs as a Docker container.

Use it to connect the agent to a Loki installation using its URL and authentication settings.

It provides an agent connection to a log service, although the available description does not list the specific operations it supports.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods

npx agentmods add mcp/lexfrei/ccc/mcp-loki-loki

Clone the repo

git clone --depth 1 https://github.com/lexfrei/ccc

Made for: Claude Code.

Or install mcp-loki, the plugin that ships this one along with the rest of its 1 MCP server.

Security

Grade A, and why

loki scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
