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.

Cubic features and specs

  • User-Friendly Interface
    Cubic provides a straightforward and intuitive interface, making it accessible even for users with limited experience in creating or customizing Linux ISOs.
  • Customizability
    Cubic allows users to easily customize Ubuntu-based distributions by installing software, tweaking settings, and adding files directly into the ISO image.
  • Real-time Preview
    The application provides a real-time preview of the ISO being customized, helping users to visualize the final product and make adjustments as necessary.
  • Enhanced Control Over Packages
    Cubic facilitates easy manipulation of package lists, including the ability to add, remove, or enable specific repositories for package installation.

Possible disadvantages of Cubic

  • Limited to Ubuntu-based Distributions
    Cubic is specifically designed for customizing Ubuntu and its derivatives, meaning it is not suitable for other Linux distributions.
  • Requires Linux Knowledge
    Despite its user-friendly interface, Cubic still requires a basic understanding of Linux commands and environment to make effective customizations.
  • Dependency on Ubuntu Packages
    Customizations are reliant on packages available within Ubuntuโ€™s repositories, which may limit the scope of modifications for users who require non-Ubuntu packages.
  • Performance and Resource Limitations
    Running Cubic can be resource-intensive, requiring significant CPU and memory usage, especially during intensive operations like large package installs or complex customization scripts.

Questions & Answers

As answered by people managing Cubic 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.
