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 iO-808 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.

  • Show HN: I built a little online drum machine using 808 style samples
    I would highly recommend enabling click and drag to "paint" notes. As it is right now, if I want 16 closed hats, I have to move, click, 16 times. I'd rather drag to paint based on whatever state of the note I start on. The mutes on the left would be better if they mute the notes, not the sounds. Muting and then enabling can end up playing the tail of some of the longer sounds. This isn't typically how you want... - Source: Hacker News / over 3 years ago

  • Best music production program for making beats?
    If thatโ€™s just about making beats, a Roland TR8 is awesome for that. Or even a Teenage Engineering PO Rythm, a jumbee or make https://io808.com his homepage. Source: over 4 years ago
  • Trying to figure out this 808 drumbeat sound from " Marvin Gaye" by Charlie Puth
    In fact, try it right now. Go to https://io808.com/ . Set the tempo dial to 3. For the bass drum (BD), enable steps 1, 7 and 8. For the snare drum (SD), enable steps 9, 15 and 16. Source: about 5 years ago
  • Zoom Escaper: self-sabotage audio, making your presence unbearable to others
    Also of note that Firefox's Web Audio API implementation just isn't very good in general. It's my daily driver, but I won't run Airsonic in it, because after half an hour or so the music reliably starts glitching. Fine in every other client, so it's definitely a Firefox thing, and iO-808 [1] also calls it out in an alert if you go there in Firefox. Granted, a glitchy audio implementation might be just the thing... - Source: Hacker News / over 5 years ago
