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.

GNU Screen features and specs

  • Session Management
    GNU Screen allows you to detach and reattach sessions, making it possible to keep applications running in the background even if you disconnect from a terminal session.
  • Multiple Windows
    It provides the ability to open multiple windows within a single terminal session, allowing you to manage different tasks concurrently without opening additional shell instances.
  • Terminal Sharing
    Screen supports terminal sharing, enabling multiple users to view and interact with the same terminal session, which is useful for collaborative work and troubleshooting.
  • Scrollback History
    You have access to scrollback history, allowing you to review command output and logs even after they've disappeared from view in the normal terminal.
  • Customizability
    GNU Screen provides extensive options for customization through its configuration file, enabling users to tailor keybindings, appearances, and functionalities to their preferences.
  • Resource Efficiency
    Being a text-based application, GNU Screen is extremely light on system resources, making it suitable for use on systems with limited computational power or memory.

Possible disadvantages of GNU Screen

  • Steep Learning Curve
    New users may find GNU Screen's interface and command syntax difficult to learn and use efficiently, especially without dedicated tutorials or documentation.
  • Outdated User Interface
    Compared to more modern terminal multiplexers like tmux, GNU Screen may feel outdated in terms of user interfaces and ease of use.
  • Limited Functionality
    While robust for basic session management, GNU Screen lacks some of the advanced functionalities and features found in newer tools, such as better scripting integrations and extended multi-pane support.
  • Configuration Complexity
    The process of configuring the .screenrc file to achieve certain custom setups can be cumbersome and unintuitive for some users.
  • Competition from Alternatives
    Alternatives like tmux offer similar functionalities with more modern features, resulting in a decline in the usage of GNU Screen among new users.

Questions & Answers

As answered by people managing GNU Screen 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.
