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.

HEY features and specs

  • Privacy-focused
    HEY places a strong emphasis on user privacy. It blocks spy pixels and prevents senders from knowing when, where, and if emails are opened.
  • Clean Interface
    The user interface of HEY is minimalist and designed to reduce clutter, helping users focus on important emails.
  • Innovative Features
    HEY offers unique features like the Screener, which allows users to vet new senders, and The Feed, which collects all newsletters for easy reading.
  • Unified Platform
    Everything in HEY happens within a single, unified platform, eliminating the need for multiple email clients or add-ons.

Possible disadvantages of HEY

  • Cost
    HEY is a paid service with a yearly subscription fee, which could be a deterrent for users accustomed to free email services.
  • Limited Integration
    Compared to other email services, HEY has limited third-party integrations which might be a downside for users who rely on external apps.
  • Learning Curve
    The unique approach and innovative features may require some time to get used to, especially for users who are accustomed to traditional email systems.
  • Lack of Local Email Client Support
    HEY does not support traditional email protocols like IMAP or SMTP, meaning users cannot use it with their favorite local email clients.

Questions & Answers

As answered by people managing HEY 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.

HEY Reviews

ProtonMail Compares Apple to Mafia, Says App Was Forced Into In-App Purchases in 2018
Apple apparently told ProtonMail "out of the blue" that it was required to add an in-app purchase option to stay in the โ€ŒApp Storeโ€Œ. Similar to the situations with HEY and Wordpress earlier this year, ProtonMail had a mention of paid plans in the app, which prompted Apple to ask for the same subscription options to be offered via in-app purchase.

  • How Solid Queue Became the Rails 8 default, and More on Open Source Maintainership
    Seven gems to manage background jobs. The team looked at what they were running and said "this can't be right." That became the brief for Solid Queue. Rosa got picked for the project, built it in production at Hey first, iterated on it for months, and shipped it into Rails 8. She keeps calling it luck. I don't think it's luck. - Source: dev.to / about 1 month ago
  • The death of cloud centralization: Last decadeโ€™s internet had a gravity problem
    Basecamp: After using clouds from both Amazon and Google extensively over the past 15 years, we finally had enough of the outrageous bills and the ever-increasing complexity. So in 2023, we pulled Basecamp, HEY, and five other heritage apps out of AWS and onto our own hardware โ€” without adding any new staff. - Source: dev.to / 11 months ago
  • From React to Hotwire - Part II - [EN]
    Attending the latest edition of Rails World and watching the talk by DHH made me realize that generating views on the backend with Rails was no longer synonymous with slow, ugly interfaces that do not care about UX. With Hotwire, through Turbo and Stimulus, it was possible to create applications as complex as Gmail, Hey, or Slack, Campfire. And this became even more surreal with Turbo 8. - Source: dev.to / about 2 years ago
  • HEY.com Review: A Game-Changer or A Gimmick?
    In June 2020, Basecamp decided to take on the giants of email service providers with the launch of HEY.com, aiming to revolutionize the way we interact with our inboxes. Touted as the email service for those who love email but hate its clutter, HEY.com has certainly generated buzz. But does it live up to the hype? Let's delve into its features, usability, and overall value proposition. - Source: dev.to / over 2 years ago
  • Don't upload your PWA to the app stores
    HEY is a big company, with financial resources and a large social media following. If even they feel bullied by Apple, just imagine what it's like for smaller app developers. And HEY is not even a PWA โ€“ it's a native app. - Source: dev.to / over 2 years ago
