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 Kosmi 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.

Kosmi Reviews

  1. Makaiya Williams

    There is this admin Foxiul, at first, he seemed like a pretty decent human being. But then all that changed. He got power-hungry. He started deleting messages, banning people from the lobby, destroying rooms, etc, etc. He banned my friend because she was sticking up for her younger sister, then banned me because he was in a bad mood when I simply said "Lol". He is turning Kosmi into a not-so-well-liked platform. many people are planning to leave Kosmi. I will be doing the same.

  • [NO SPOILERS] Invitation for Arcane online WATCH PARTY this weekend
    So if enough people comment here and are down to watch, I'm gonna be hosting the watch party on Kosmi. As I explained in the last post, Kosmi is a website to screenshare, so I'm gonna create the stream from there and we can all watch together. Source: almost 3 years ago
  • USA ... EU... Is there a TV / or method for watching together?
    Go on sl and buy a Kosmi TV. Or just use the webpage url on any prims media. https://kosmi.io/ It basically streams any browser wondow with w/e show on it. And it's real time. We have a Kosmi TV n watch any streaming service or movies together on it. Source: over 3 years ago
  • How do you watch movies long distance?
    Kosmi.io worked for us so far. But I'm planning to set-up our own instance of neko (https://github.com/m1k1o/neko) to give that a shot. Both are essentially browsers hosted in the cloud. So that has the advantage, that only one streaming account is required. Source: over 3 years ago
  • How can I stream PC games to a local TV for my wife to watch me play?
    True. I guess I was thinking that if maybe they were in the same room. And you could use the audio from the TV. People mentioned discord, but I feel like you could use the TV browser and just use https://kosmi.io/. Source: over 3 years ago
  • SURL/LM for a public location using the Kosmi TV?
    It's totally different from the other inworld TV's in that it's designed around kosmi.io for sharing streams and other things from one's local computer. You can use it, for example, to play a Netflix or HBO movie on the Kosmi TV so people inworld can also see it. Source: over 3 years ago
