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.

Cube.js features and specs

  • Open Source
    Cube.js is open-source, meaning it's free to use and has a community of developers contributing to its improvement. This fosters collaboration, transparency, and faster iteration of features and bug fixes.
  • API-First Approach
    Cube.js provides an API-first approach, allowing you to easily integrate it into existing applications and workflows. This flexibility makes it suitable for a variety of use cases.
  • Pre-Aggregations
    Cube.js includes built-in support for pre-aggregations, significantly speeding up query performance by pre-calculating data and reducing the load on your database.
  • Database Compatibility
    It supports multiple databases like PostgreSQL, MySQL, MongoDB, and more, making it versatile and adaptable to different environments and technology stacks.
  • Scalability
    Cube.js can handle large datasets and high query loads, making it a scalable solution for growing applications or enterprises with extensive data needs.
  • Community and Documentation
    Cube.js has a strong community and comprehensive documentation, which can aid in troubleshooting, implementation, and learning best practices.

Possible disadvantages of Cube.js

  • Learning Curve
    Despite the comprehensive documentation, Cube.js can have a steep learning curve due to its wide range of features and the complexity of setting up pre-aggregations and schema design.
  • Performance Overhead
    For smaller applications, the performance overhead introduced by Cube.js might not justify its use, as the pre-aggregation and processing layers could add complexity without substantial performance gains.
  • Dependency on JavaScript/Node.js
    Cube.js is built on JavaScript and Node.js, which can be a limitation if your development stack relies primarily on other technologies, leading to potential integration challenges.
  • Community Support Limits
    While Cube.js has a decent community, it's not as extensive as some older, more established data processing or BI tools. This could result in fewer third-party integrations and plugins.
  • Initial Setup Time
    Setting up Cube.js initially can be time-consuming, particularly when configuring data schemas, security, and managing pre-aggregations for optimized performance.
  • Evolving Software
    As a relatively new and evolving tool, Cube.js might experience more frequent updates or changes, which could lead to stability issues or require continuous adaptation of your application.

Questions & Answers

As answered by people managing Cube.js 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.
