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.

Builder.io features and specs

  • Visual Headless CMS
    Visual CMS is a headless content management system (CMS) that helps digital teams build, ship, and iterate content significantly more efficiently by giving marketers a drag-and-drop interface for building and editing digital experiences without depending on developer support. It integrates with existing components and any modern tech stack so developers can work more efficiently to ship high-performance web and mobile experiences for any scale.
  • Visual Copilot
    Visual Copilot is an AI-enabled design-to-code tool that helps digital teams automatically turn Figma designs into code that's as clean, semantic, and accessible as the code a developer would have written themselves. Unlike other design-to-code tools, it automatically makes designs responsive, lets you chat to iterate the code with AI, and generates code that leverages your existing components when you have them.

Questions & Answers

As answered by people managing Builder.io and Emisar.dev.

What makes your product unique?

Builder.io's answer

Builder is driving the next generation of front-end programming, with the only Visual Development Platform that offers an AI-powered design-to-code tool, a visual editor, and an enterprise CMS.

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. [

What's the story behind your product?

Builder.io's answer

Our founders, Steve Sewell and Brent Locks, met on the campus of UC Berkeley in 2011, and have been friends and colleagues ever since. In those early days, they bonded over wanting to be entrepreneurs, and having lots of ideas, but not knowing how to code to bring them to life.

Fast forward more than a decade, and Steve is now a visionary technologist (Brent's words) and Brent still doesn't know how to code (beyond some basic HTML and CSS), but they continue to share a passion around building technology that can enable anyone to bring their ideas to life, which is at the core of Builder.io.

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.

How would you describe the primary audience of your product?

Builder.io's answer

Frontend engineering leads who manage a headless site or store. Frontend and full-stack web developers whose team uses Figma to design web and app experiences

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.

Why should a person choose your product over its competitors?

Builder.io's answer

Shipping, iterating, and optimizing high-performing digital experiences eats up a ton of time. As a result, teams donโ€™t get nearly as many experiences, pages, content, or experiments to market as they planned. Builder helps teams ship twice as much, without doubling their effort or team size. Builder does this by offering tools that optimize every step of the journey from design through optimization. No other tool comes close because they donโ€™t consider the entire journey and havenโ€™t embedded AI at the same level as Builder. As a result of shipping twice as much with the same team size, companies can significantly increase top-line revenue or decrease costs.

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.

Who are some of the biggest customers of your product?

Builder.io's answer

  • Zapier
  • Anheuser-Busch
  • Everlane
  • JCREW
  • PetLab.co
  • Fabletics
  • Harry's

Emisar.dev's answer:

  • Blitz.gg - game analytics for billions of matches and a pretty large infrastructure.

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.
