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 OnlyFlights and Emisar.dev.

Why should a person choose your product over its competitors?

OnlyFlights's answer

You should choose OnlyFlights over other apps because itโ€™s fast, private, and stress-free. Unlike some flight apps, it doesnโ€™t ask you to create an account or show you annoying ads. It gives you just what you need - like real-time flight updates, delay alerts, and a clean travel log - without any extra clutter. Plus, itโ€™s really affordable if you want to track more than two flights. Perfect for travelers who want a simple tool that just works.

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.

What makes your product unique?

OnlyFlights's answer

OnlyFlights is unique because itโ€™s super simple and easy to use. You donโ€™t need to sign up or deal with ads, and it doesnโ€™t track your data. It focuses only on flight tracking, with clean design and useful features like live flight alerts, a countdown to your next flight, and a travel history log. Itโ€™s made for people who just want to track flights without any extra noise.

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. [

How would you describe the primary audience of your product?

OnlyFlights's answer

The primary audience for OnlyFlights is travelers who want a simple and reliable way to track their flights. This includes frequent flyers, casual travelers, flight crews, and even people picking someone up from the airport. These travelers care about staying updated but donโ€™t want to deal with ads, sign-ups, or complicated apps.

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's the story behind your product?

OnlyFlights's answer

The story behind OnlyFlights started with Kate and Alex, the creators of the Time2Pack app. At first, they added a flight tracking feature inside Time2Pack, just to help travelers stay more organized. But soon, users began asking for a separate app that focused only on flight tracking. So, after getting lots of feedback, they decided to build OnlyFlights as a standalone app - simple, focused, and designed just for tracking flights without distractions.

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.

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.
