Emisar is the last MCP server youโ€™ll need to install: a Zero-Trust gateway connecting Claude, Cursor, ChatGPT, and any AI agent to your infrastructure. One server handles production access, debugging, alerts, and internal operations, with new capabilities added as packs. Agents can inspect real production state, debug what they shipped, and help resolve incidents. Safe reads run automatically; policy allows, blocks, or routes risky actions for approval. No SSH keys, VPNs, remote shells, or standing shell access โ€” and every call is recorded.

CoreOS features and specs

  • Lightweight and Minimalistic
    CoreOS is designed to be a minimalistic operating system, which reduces overhead and optimizes performance by focusing on running containers efficiently.
  • Automatic Updates
    It provides automatic updates for the entire OS, ensuring up-to-date security patches and system enhancements without disrupting the running applications.
  • Container-Optimized
    CoreOS is built for containerized environments, making it highly suitable for organizations adopting Docker or Kubernetes for scalable and consistent application deployment.
  • Distributed Key-Value Store
    Includes etcd, a distributed key-value store for shared configuration and service discovery, enabling easy coordination among applications and services.
  • Security
    CoreOS enforces strong security practices by deploying applications in containers, leveraging automatic updates, and using SELinux policies to provide robust security mechanisms.

Possible disadvantages of CoreOS

  • Learning Curve
    Users familiar with traditional Linux distributions might face a learning curve due to CoreOSโ€™s unique approach and reliance on container orchestration.
  • Limited Use Cases
    As CoreOS is optimized for containerized applications, it may not be suitable for traditional workloads or environments that do not leverage containers.
  • Dependency on Cloud Infrastructure
    CoreOS often relies on cloud infrastructure features for orchestration and deployment, which may not fully align with the needs of on-premise environments.
  • Reduced Customization
    The minimalistic design might limit system-level customizations, making it less flexible for users who need specific custom configurations at the OS level.
  • Fragmented Ecosystem
    Following its acquisition by Red Hat, there might be uncertainties or fragmentation related to its integration into Red Hatโ€™s ecosystem and ongoing support.

Questions & Answers

As answered by people managing CoreOS and Emisar.dev.

How would you describe the primary audience of your product?

Emisar.dev's answer:

emisar is for SRE, DevOps, platform engineering, infrastructure, and security teams that want AI agents to inspect and operate production systems. It is especially relevant to teams managing multiple Linux hosts, clusters, databases, cloud services, or regulated environments where unrestricted shell access and incomplete audit records are unacceptable.

Which are the primary technologies used for building your product?

Emisar.dev's answer:

The hosted control plane and operator interface use Elixir, Phoenix, LiveView, PostgreSQL, and Tailwind CSS. The host runner and MCP bridge are written in Go. Action packs use YAML and JSON Schema, while production infrastructure is managed with Terraform on Google Cloud. The system communicates through MCP, OAuth 2.1, TLS, and WebSockets.

Who are some of the biggest customers of your product?

Emisar.dev's answer:

  • Blitz.gg - game analytics for billions of matches and a pretty large infrastructure.

What's the story behind your product?

Emisar.dev's answer:

Founder Andrii Dryga spent a decade working as a CTO, full-stack engineer, SRE, and DevOps engineer. He experienced the cost of running the wrong command on the wrong cluster, while also seeing AI solve operational problems in seconds. emisar grew from the need to preserve both truths: AI agents are useful, and production access must remain bounded. Its answer is to give agents a reviewed catalog of operations instead of a blank terminal.

What makes your product unique?

Emisar.dev's answer:

emisar lets AI agents work on real infrastructure without giving them a shell. Agents choose from a finite catalog of typed, versioned actions. Policy decides what runs, what requires approval, and what is denied, while an outbound-only runner verifies the action again on the host. New capabilities arrive as packs behind the same MCP integration, and every request is recorded in both a searchable audit trail and a tamper-evident host journal. [

Why should a person choose your product over its competitors?

Emisar.dev's answer:

Choose emisar when you want an agent to keep investigating and handling routine operations without handing it SSH credentials or supervising every call. Compared with raw shell access, copy-paste workflows, or one-off MCP servers, emisar provides reviewed action contracts, host-level enforcement, risk-based policy, scoped access, approvals, pack integrity checks, and a durable audit trail. It is built specifically for governed infrastructure access rather than generic automation.
