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.

    LibreCAD is completely free to use, and its open-source nature allows users to modify and improve the software according to their needs.
  • Cross-Platform
    The software is available for Windows, macOS, and Linux, ensuring that users on different operating systems can utilize it without compatibility issues.
  • Lightweight
    LibreCAD is not resource-heavy, making it suitable for older computers and systems with limited hardware capabilities.
  • 2D CAD Focus
    Specialized for 2D design, making it easier for users who specifically need 2D drafting tools as it avoids the complexities associated with 3D modeling.
  • Customizable Interface
    Users can tailor the interface to better suit their workflow, enhancing productivity and ease of use.
  • Active Community Support
    An active community provides support, documentation, and forums for troubleshooting and advice, making it easier for users to solve problems and learn new features.

Possible disadvantages of LibreCAD

  • Limited 3D Capabilities
    LibreCAD is primarily a 2D CAD software and does not support 3D modeling, which can be a limitation for users needing advanced spatial design tools.
  • Steeper Learning Curve for Beginners
    While powerful, the software can be challenging for new users unfamiliar with CAD software, requiring a significant amount of time to learn.
  • Fewer Advanced Features
    Compared to some professional CAD packages, LibreCAD lacks some of the more advanced features and tools, which can limit its use in complex projects.
  • Limited File Format Compatibility
    LibreCAD primarily supports DXF format, and while it can read/write other formats, the compatibility is not as comprehensive as some other CAD software.
  • Occasional Stability Issues
    Some users have reported crashes and bugs, which can be problematic for those working on time-sensitive projects.
  • Sparse Documentation
    While there is community support, the official documentation can be lacking in detail, making it difficult for users to find thorough guidance on complex tasks.

Questions & Answers

As answered by people managing LibreCAD 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.

  • If I don't use Windows or Mac and only use Linux, will I run into a lot of compatibility issues?
    CAD options on Linux are more limited than windows or mac but they do exist. The industry standard for 2d CAD files is the .dxf file format. I use LibreCAD. https://librecad.org/ The UI is a little clunky and eccentric in places but it is feature complete for 2d CAD drawings. Source: over 3 years ago
