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.

Blitz.js features and specs

  • Fullstack Framework
    Blitz.js provides a cohesive experience by integrating both frontend and backend, enabling developers to focus more on building features than managing infrastructure.
  • Built on Next.js
    Being built on Next.js, Blitz.js benefits from the mature, well-maintained foundation of Next.js including its advanced routing, rendering optimizations, and powerful features.
  • Zero-API Data Layer
    Blitz.js eliminates the need for REST or GraphQL for client-server communication by allowing direct database access across the app, simplifying data management.
  • Community and Plugins
    A vibrant community and a growing ecosystem of plugins make it easier to extend and customize Blitz.js applications.
  • Authentication
    Blitz.js comes with built-in authentication and authorization, reducing the time and effort needed to implement security features in applications.

Possible disadvantages of Blitz.js

  • Learning Curve
    For developers coming from traditional REST or GraphQL backgrounds, adjusting to Blitz.js's paradigm, especially the data layer, may take some time.
  • Early Stage
    As Blitz.js is relatively new, it may lack the stability, full-fledged documentation, and extensive community support found in more established frameworks.
  • Opinionated
    Blitz.js follows specific conventions and patterns, which might limit flexibility for developers wanting to deviate significantly from its architecture.
  • Compatibility
    Some existing libraries or tools might not yet fully support or integrate seamlessly with Blitz.js, potentially requiring additional effort or workarounds.
  • Performance Overhead
    The zero-API approach, while simplifying development, might introduce unanticipated performance overheads in certain scenarios, especially with large-scale data operations.

Questions & Answers

As answered by people managing Blitz.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.
