What is flux-operator-mcp?

A read-only connection to Flux Operator for managing Kubernetes resources. Kubernetes is software for running and coordinating containers, and read-only access means the connection can inspect resources but not change them.

Use it to inspect Flux Operator and related Kubernetes resources when diagnosing or reviewing deployments.

It lets the agent examine the current Kubernetes state while lowering the risk of accidental changes during investigation.

flux-operator-mcp — MCP server by devantler-tech/agent-plugins

Install

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.

Clone the repo

git clone --depth 1 https://github.com/devantler-tech/agent-plugins

Installing this writes the configuration, not the program: `sh` has to be on your PATH already, or the server will not start.

Made for: Claude Code.

Or install agentic-engineering, the plugin that ships this one along with the rest of its 87 skills, 4 agents, 11 MCP servers.

Security

Grade C, and why

flux-operator-mcp scanned grade C with 1 finding 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 yesterday.

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.

Reaches for credential fileshighPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

This page is one entry in a file that holds 11. Installing the file brings all of them; each is measured and scanned on its own page.

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.

flux-operator-mcp is an MCP server published in the GitHub repository devantler-tech/agent-plugins (3 stars, last pushed yesterday), licensed Apache-2.0. Its token cost is not measured: an MCP server costs its tool schemas, not its config file. A static security scan graded it C with 1 finding (reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-11-05.
