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 Resend 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.

  • Getting Your Writing Seen Beyond Your Own Site
    Two practical pieces. First, you need a transactional sender that can do broadcasts. I use Resend because the API is good, the React Email integration is good, and the dashboard is sane. Postmark and AWS SES work fine too. Second, on every publish, send a broadcast to your audience. This is the closest thing you have to a guaranteed reader. - Source: dev.to / about 1 month ago
  • How to Send Transactional Emails with Vue and Resend
    Resend has quickly become the default way to send email from modern applications. The API is clean, the deliverability is good, and the developer experience is impressive. But Resend only handles sending emails. It provides a html field and you produce the HTML that you've ensured is compatible with Gmail, Outlook, and the many other email clients. - Source: dev.to / about 2 months ago
  • Adding comments to a static Astro blog with Netlify Forms
    Netlify/functions/comment-handler.js is triggered by a Netlify outgoing webhook Whenever a new submission hits the blog-comments queue. It sends an HTML email Via Resend (the same delivery layer used for new post notifications) containing the comment text and two HMAC-SHA256-signed action links:. - Source: dev.to / 2 months ago
  • How I migrated magic-link login from Resend to AWS SES + Lambda five days before launch
    I run toui.io, a URL shortener I shipped to the public on April 7, 2026. Eleven days before launch I had passwordless email login working on Resend. Five days before launch I tore it out and rebuilt the same flow on AWS โ€” Lambda + DynamoDB + SES + API Gateway, packaged as a SAM stack. - Source: dev.to / 2 months ago
  • Build personalized email campaigns per customer
    Whatever you already use for transactional email (Resend, AutoSend, etc.). A CSV or database of customers is enough for the last step. - Source: dev.to / 2 months ago
