Emisar is the last MCP server youโll 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.

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.
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.

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.
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. [
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.

Super cool roster!

Not a direct learning resource, but a few quick tips: 1) Know what language you're targeting beforehand, if possible (e.g. Javascript regex or Perl regex or POSIX regex, etc.). There are a lot of different regex "dialects" (kinda like SQL dialects) and the operators aren't always compatible, and not every implementation supports all the features (like "negative lookaheads"). 2) Railroad diagrams can be really... - Source: Hacker News / over 1 year ago
That's my go-to these days, but sometimes I like to see a diagram from this one: https://regexper.com I've just slowly learnt it by experimenting with it over the past few years. People have mostly mentioned matching, but I use it more for string manipulation. I'm still not as intermediate a programmer as I'd like to be, so it's great when I need to invert a design decision for example. A similar code structure in... - Source: Hacker News / almost 2 years ago
Regexper takes your regular expressions to the next level. It generates interactive, visually appealing diagrams that help you understand your regex patterns. With Regexper, you can see your regex patterns come to life, making complex expressions easier to grasp. - Source: dev.to / almost 3 years ago
If it's a one-off regex to scrape some data and you verify the output, great. If it's to be used in an application and you don't understand it, that could be an issue. There's some great online tools to convert regex to railroad diagrams like https://regexper.com/ which I recommend if you don't understand some regex AI produced. Source: over 3 years ago
