Kubently - Troubleshooting Kubernetes Agentically
Overview
Kubently (Kubernetes + Agentically) is a free, self-hosted, vendor-neutral multi-cluster Kubernetes troubleshooter. Ask one question, get AI-diagnosed answers from every cluster in your fleet in parallel — including clusters you can't reach directly: executors dial outbound to the central API, so there's no inbound ingress, no shared kubeconfig, and no per-cluster credentials to distribute.
Agents collaborate over the A2A (Agent-to-Agent) protocol, and any MCP client (Claude Code, Cursor, Claude Desktop) can use Kubently as a tool out of the box.
Key Features
- Multi-Cluster Fleet Troubleshooting: One question fans out across all registered clusters in parallel
- Outbound-Dial Executors: Reach clusters behind firewalls/NAT — no inbound ingress, no shared kubeconfig
- Natural Language Interface: Conversational Kubernetes troubleshooting and debugging
- Comprehensive Analysis: Automated issue detection, root cause analysis, and solution recommendations
- Multi-LLM Support: Compatible with Google Gemini, OpenAI, Anthropic, and other providers
- A2A Protocol: Industry-standard agent-to-agent communication for complex workflows
- MCP Server: Optional Model Context Protocol endpoint so MCP clients (Claude Desktop, Cursor, custom agents) get direct tool access
- Security-First: API key authentication, OAuth/OIDC support, and TLS with cert-manager
- Persistent Sessions: Redis-backed conversation history and context management
- Extensive Tool Suite: kubectl integration, log analysis, resource inspection, and more
Quick Start
For Users: Get Started in 5 Minutes
Point kubectl at any cluster (kind, minikube, or real) and run:
npm install -g @kubently/cli
kubently installThat's it. The CLI installs Kubently via Helm, wires up secrets and the executor, port-forwards the API, and drops you into a debug chat:
kubently> why is my nginx pod crashlooping?You'll need an LLM API key (Anthropic, OpenAI, or Google) — the installer prompts for it, or reads ANTHROPICAPIKEY / OPENAIAPIKEY / GOOGLEAPIKEY from your environment. Use --provider to pick the LLM, --chart ./deployment/helm/kubently to install from a local checkout, and kubently install --help for everything else.
Use from Claude Code / Cursor (MCP)
Already ran kubently install? Add Kubently to Claude Code:
claude mcp add kubently -- kubently mcpOr connect directly over HTTP (no bridge process):
claude mcp add --transport http kubently http://localhost:8080/mcp/ \
--header "X-API-Key: <your-api-key>"Then ask Claude things like "use kubently to figure out why payments pods are crashlooping". Any MCP client works — see docs/MCP.md for Cursor and generic configuration.
Proactive diagnosis (Alertmanager → Slack)
Set api.env.SLACKWEBHOOKURL to a Slack incoming-webhook URL and point Alertmanager at Kubently:
Shortened. The full README is on GitHub.
Nothing above is checked by us. What we check is on the safety report.
Install directly
Runs npx -y @kubently/cli on your machine. Read the scan report first; the gateway never runs local packages.
claude mcp add kubently -- npx -y @kubently/cli
Kubently: common questions
- Is Kubently MCP server safe?
- Mostly: it is graded B (75/100). Read the Kubently safety report
- How do I install Kubently?
- It runs on your machine. Copy the Claude Code, Claude Desktop or Cursor config from the install section.
- Does Kubently need an API key?
- Not as far as the registry entry and our scan can tell: no credentials are declared or required.
- Is Kubently maintained?
- The last commit was 5 days ago (2026-09-21). The latest release is v2.3.1.
- What can I use instead of Kubently?
