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.

Questions & Answers

As answered by people managing NightOwl 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.

NightOwl mentions (8)

  • New To Mac
    I use dark mode, but there are some apps which are (IMO) just plain ugly in dark, like the calendar and mail. You could use an app like NightOwl. But there is a command for that. It's got two steps, firstly find the app's bundle id, using osascript -e 'id of app "App_Name"'. Then pass this result into: defaults write NSRequiresAquaSystemAppearance -bool Yes.

  • Mac won't switch to dark mode
    I had this issue a lot - instead of relying on the auto mode I went ahead and installed NightOwl. Now the theme changes correctly at the appropriate time. Source: about 4 years ago
  • Automatic Dark/Light Mode based on sunset/sunrise?
    Sadly, this functionality isn't built-in to Windows and (unlike macOS) there doesn't appear to be any decent third-party utilities to sort this out for you. To date, I've been using an Open-Source offering named Luna. Source: over 4 years ago
  • No "Night Shift" in preferences for my Mac Mini M1?
    For changes at exact times, use a third party util like NightOwl. Source: almost 5 years ago
  • [macOS 11.4, MBP M1] Been dark for a while outside, but the auto appearance still goes to light mode, but it works correctly on iOS.
    I just gave up with the default Mac settings downloaded NightOwl. Night Shift works as normal but NightOwl ensures that dark mode turns on at sundown. Source: about 5 years ago
