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 Charmstone 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.

  • macOS Needs Its Grid Back
    I use Charmstone for spatial app switching - https://charmstone.app/ Not the same as full spaces, but it gives the same vibe of always having a particular app on a particular hotkey. I try to limit my multi-tasking though, so I can imagine where full spaces would be useful. - Source: Hacker News / about 2 months ago
  • Past and Present Futures of User Interface Design
    If OSes were optimized like RTS games, maybe the mouse could be plenty fast. Something like https://charmstone.app/ but for many actions. - Source: Hacker News / over 1 year ago
  • App LIST!!!
    Charmstone (Paid) The quicker switcher launcher for macOS, same as Rcmd. Just another choice I guess. Source: over 3 years ago
  • Help Identifying a Floating App Launcher
    Not exactly what you are describing: Charmstone. Source: over 3 years ago
  • You're using function keys wrong
    Charmstone [1] is a different take from everything mentioned here (I'm the developer). The idea is to use your spatial memory to switch/launch apps faster than anything else that I've found, with a smaller learning curve and less memorization. You can use keyboard shortcuts with the arrow keys, modifier keys + cursor movement, or a trackpad gesture. [1] https://charmstone.app. - Source: Hacker News / over 3 years ago
