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.

Questions & Answers

As answered by people managing PDFBolt and Emisar.dev.

Which are the primary technologies used for building your product?

PDFBolt's answer

  • Kotlin
  • Spring
  • PostgreSQL
  • Redis
  • React
  • Firebase
  • Playwright

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.

How would you describe the primary audience of your product?

PDFBolt's answer

Our primary audience includes:
โœ… Developers looking for a fast and reliable API to automate document workflows.
โœ… SaaS companies needing dynamic report generation or invoice automation.
โœ… Businesses in finance, legal, or eCommerce seeking GDPR-compliant solutions for generating PDFs like contracts, invoices, and receipts.
โœ… Anyone who needs a simple, secure, and scalable solution for generating high-quality PDFs.

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.

What makes your product unique?

PDFBolt's answer

๐Ÿš€ PDFBolt combines speed, security, and ease of use in one platform. It offers a developer-friendly API with sync and async options, pixel-perfect PDF generation powered by Chrome, and GDPR-compliant privacy features like direct upload to your own S3 bucket.

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?

PDFBolt's answer

โœจ PDFBolt was created to solve the frustration developers face with slow and complicated HTML to PDF solutions. Our mission is to provide a simple, fast, and secure API that helps businesses automate their workflows, enhance productivity, and scale efficiently. We built PDFBolt to make pixel-perfect PDF generation as straightforward as possible, without compromising on quality or privacy.

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.

Why should a person choose your product over its competitors?

PDFBolt's answer

โšก PDFBolt stands out with 500 free conversions per month to get started. Unlike many competitors, it offers both synchronous and asynchronous API calls, customizable document formatting, and seamless webhook integration for automation, all while prioritizing security and scalability.

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?

Emisar.dev's answer:

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

    Iโ€™m working on PDFBolt, a PDF generation API for developers. https://pdfbolt.com Itโ€™s for the boring pdf jobs every SaaS eventually gets: invoices, reports, certificates, contracts, labels, that kind of thing. You send html, a url, or a template with JSON data, and get a PDF back. Last week we shipped the Node SDK. Right now Iโ€™m working on the Python SDK and tightening up the docs. - Source: Hacker News / about 2 months ago

    Working on PDFBolt (https://pdfbolt.com) - a PDF generation API. You send HTML, a URL, or a Handlebars template with JSON data, get a PDF back. Uses Playwright underneath so modern CSS just works. Lately been deep in PDF/X print production - PDF/X-1a and PDF/X-4 with ICC color profiles and CMYK conversion.

  • Ask HN: What Are You Working On? (February 2026)
    Https://pdfbolt.com A PDF generation API, Chrome-based. Most of my time lately goes into print production - browsers render everything in RGB but print needs CMYK with ICC color profiles, and getting that conversion right inside the PDF turned out to be a much deeper problem than expected. Got PDF/X-1a and PDF/X-4 working now. - Source: Hacker News / 6 months ago
