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.

PDFJet features and specs

  • Cross-Platform Compatibility
    PDFJet is written in Java, making it compatible with any platform that supports the Java Virtual Machine (JVM), allowing for easy integration across various systems.
  • Comprehensive Feature Set
    Offers a broad range of features for creating and manipulating PDF files, such as drawing graphics, embedding fonts, and adding annotations, suitable for complex document workflows.
  • No External Dependencies
    PDFJet is a standalone library with no external dependencies, simplifying deployment and reducing potential compatibility issues with other software.
  • High Performance
    Designed to handle large documents efficiently, PDFJet can be used for performance-sensitive applications requiring fast PDF generation.
  • Licensing Flexibility
    Available under both commercial and open-source licenses (AGPL), allowing developers to choose a licensing model that suits their needs.

Possible disadvantages of PDFJet

  • Limited Documentation
    Users may find the documentation lacking in detail, making it challenging for new users to understand or utilize all the library's features without extensive experimentation.
  • Complexity for Simple Tasks
    For users looking to perform basic PDF manipulations, PDFJet may be overkill due to its extensive feature set and potential learning curve.
  • AGPL Licensing Restrictions
    While AGPL offers an open-source option, it requires users to provide the source code of their applications if they distribute binaries, which might not be suitable for all projects.
  • No Official Support for Other Languages
    As a Java library, integration with non-JVM languages may require additional tools or wrappers, which could complicate its use in some development environments.
  • Cost for Commercial Use
    Commercial licenses incur a cost, which may be a deterrent for small businesses or individual developers when compared to fully open-source alternatives.

Questions & Answers

As answered by people managing PDFJet 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.
