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 SENDER 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.

SENDER Reviews

  1. Jerry Hamilton
    ยท Marketing Manager ยท
    Three years in, still impressed with the value

    I jumped ship from Mailchimp to Sender back in 2022, and it's been one of my better business decisions. My monthly email costs immediately dropped from $20 to zero, while I got more features to work with. The interface makes sense right away โ€“ no need to watch hours of tutorials. Recently they threw in a landing page builder too, which saved me another subscription.

    ๐Ÿ‘ Pros:    The free tier covers what most small businesses need. you can get campaigns running in under an hour without any prior experience. automation is simple but covers the basics โ€“ cart abandonment, welcome series, follow-ups, etc.
    ๐Ÿ‘Ž Cons:    Some of the fancier segmentation options aren't immediately obvious, and the template selection could use more variety for different industries.

  • Inserting Newsletter Sign-up Button in Articles Question
    I use sender.net for my newsletter and write a sports blog in wordpress. In article, I'd like to put the small form to sign up for the newsletter (see link) into the articles. I know how to float it so it wraps text around it in a desktop-tablet setting but when you view it on mobile, it still wraps the text around and is a rough UX. Source: over 3 years ago
  • Best free site for blogs?
    For example, you can get web hosting for a wordpress site for as little as $2 per month (that's what I'm paying here in Sweden with Inleed, and we're an expensive country). You'll also need a domain name, which will cost you some $15 per year. A total of $40 per year, and everything else, (including the all-important email list) you can get for free (I use sender.net).

  • Freedom-Of-Speech
    I need to find a solution for this individual. I'd prefer to use a generic email-campaign service, but with the research that I've done, I cannot find one that supports free speech. The closest one was Sender.net, however in their Terms of Use, it talks about hate speech as being disallowed. That term is thrown around WAY too much in today's society and there isn't one set definition that follows it. Therefore, it... Source: over 5 years ago
