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.

Yay features and specs

  • AUR Support
    Yay provides seamless support for Arch User Repository (AUR) packages, allowing users to easily search for, install, and update AUR packages along with official repository packages.
  • Combined Package Management
    It combines both AUR and official repository package management in one tool, streamlining the process and reducing the need to use multiple package managers.
  • User-Friendly Interface
    Yay offers a user-friendly command-line interface with clear prompts and options, making it easier to navigate and use than some other AUR helpers.
  • Speed and Efficiency
    Thanks to its optimized codebase and use of go programming language, Yay is typically faster than some alternatives, enhancing the overall system update process.
  • Interactive Search
    It provides an interactive search feature, allowing users to conveniently search for packages without leaving the terminal interface, enhancing user experience.

Possible disadvantages of Yay

  • Dependency Management Complexity
    Managing dependencies for AUR packages can become complex and may require manual intervention, particularly with packages that have many dependencies or conflicts.
  • Potential for Inexperienced User Errors
    As with any AUR helper, misuse by inexperienced users could potentially lead to system instability if non-vetted or conflicting packages are installed.
  • Security Risks
    Since AUR packages are user-submitted, there is an inherent security risk involved with installing them, as they may not receive the same scrutiny as official repository packages.
  • Limited Official Support
    While Yay is popular and widely used, it is not officially supported by Arch Linux, and users must turn to community forums for support and troubleshooting.
  • Dependency on the Go Language
    As Yay is written in Go, it requires Go runtime for compilation from source, which might be an inconvenience for some users who prefer not to have additional language runtimes.

Questions & Answers

As answered by people managing Yay 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.
