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 ActivityWatch 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.

  • RewindOS โ€“ Searchable screen history for Linux local
    Hi HN. RewindOS captures your screen every few seconds, OCRs it, and makes everything you've ever seen instantly searchable โ€” all 100% local. No cloud, no account, no telemetry. MIT-licensed, and built specifically for Linux/Wayland. I started out using [ActivityWatch](https://activitywatch.net/), which is great at what it does โ€” but it tracks how much time you spend in each app, not what you actually... - Source: Hacker News / about 1 month ago
  • EFF Launches Age Verification Hub as Resource Against Misguided Laws
    Ah okay. I think this would probably be pretty tricky, security-wise, no? One of my first thoughts that might help would be writing a simple tool that parses history from your browsers to categorize it. Other than that, there are things like https://activitywatch.net/ (which seems to have a desktop and Android version). - Source: Hacker News / 8 months ago
  • Recall for Linux
    It's an actual useful feature, it's just the tracking by microsoft that makes it meh. I also track my activities with ActivityWatch (Open Source, https://activitywatch.net/) to remember missing time entries for billing clients. It's all local, so perfectly fine. - Source: Hacker News / 9 months ago

  • Everyone knows all the apps on your phone
    > How hard would it be for an app to monitor all of your web traffic based on the title alone? Although not terribly accurate (because of the high variability of page titles), tools like ManicTime and ActivityWatch use windows titles to track your browser history if you don't install the browser plugin. https://www.manictime.com/ https://activitywatch.net/. - Source: Hacker News / over 1 year ago
