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.

EJS features and specs

  • Simplicity
    EJS is easy to learn and use, especially for developers who are already familiar with JavaScript. The syntax is straightforward, making it a good choice for quick application development.
  • JavaScript Integration
    Since EJS templates are JavaScript files, you can seamlessly integrate JavaScript code, making it easy to manipulate data and use familiar JavaScript functions.
  • Lightweight
    EJS is a lightweight template engine, which makes it an optimal choice for applications where performance and simplicity are critical.
  • Flexibility
    Allows for the embedding of plain JavaScript within the templates, giving developers the flexibility to add logic directly in their HTML.
  • Partial Templates
    Supports partials, which help to reuse code snippets across different views, promoting DRY (Don't Repeat Yourself) principles.
  • Server-Side Rendering
    Supports server-side rendering, which can improve performance by reducing the amount of client-side processing needed.

Possible disadvantages of EJS

  • Limited Functionality
    Compared to more feature-rich template engines like Handlebars or Pug, EJS offers limited functionalities which might be a drawback for large, complex projects.
  • Debugging
    Debugging EJS templates can sometimes be challenging. Errors within templates can often be vague, making it difficult to trace the root cause.
  • Maintenance
    Embedding a lot of JavaScript within templates can make the code harder to read and maintain, especially as the complexity of the application grows.
  • Performance Overhead
    For very large and complex templates, EJS can introduce a performance overhead compared to more optimized template engines designed for high performance.
  • Community and Support
    While EJS has a reasonable user base, the community and support may not be as extensive as more popular alternatives like React or Vue.js.

Why this product is good

  • EJS (Embedded JavaScript Templating) is popular because it provides a simple way to generate HTML markup with plain JavaScript. It allows for the embedding of JavaScript logic within your HTML templates, making it straightforward to use for those familiar with JavaScript. It's known for its efficiency in rendering templates and ease of integration with Node.js applications.

Recommended for

    EJS is recommended for developers building server-side web applications using Node.js and those looking for a simple, yet effective, templating solution. It is particularly suitable for small to medium-sized projects where dynamic content generation is needed and for teams that prioritize simplicity and performance.

Questions & Answers

As answered by people managing EJS 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.

  • Next.js vs Express: What to Choose in 2025?
    Express does not provide SEO benefits by default and would require additional configuration with tools like EJS (Embedded JavaScript) or Handlebars for server-side rendering. - Source: dev.to / over 1 year ago
  • Chapter 7: HTML part two
    For a more robust approach, we'd probably need to install a templating language of some kind, such as Twig, EJS, Handlebars, Pug or Mustache (this is not a complete list!). Reading the documentation for posthtml-modules, you'll notice it doesn't mention package.json or any of the approaches we've used in this guide. Instead, the examples are in JavaScript and we've advised to add this to our Node application. - Source: dev.to / over 1 year ago
  • Web Components and SSR - 2024 Edition
    Server-side Framework SSR is when you use a framework that runs the HTML templating logic entirely on the server to compose the HTML that will be rendered in the browser. These are frameworks like Ruby on Rails, ASP.Net, PHP, or even Node.js frameworks that use templating languages like Pug or EJS. - Source: dev.to / over 1 year ago
  • How to Build an Application With Node.js
    We need a templating engine to render HTML code in the browser using Node.js. We'll use ejs (Embedded JavaScript) for this tutorial but there are others such as Pug (formerly known as Jade) and Express Handlebar, which also render HTML on the server. - Source: dev.to / almost 2 years ago
  • Getting to the meat and potatoes of serverless recipe parsing with Amazon Bedrock
    The tags is where you put the HTML you want Claude to read. The <%- document %> contained within is an ejs placeholder. More on this shortly. - Source: dev.to / about 2 years ago
