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.

Briar features and specs

  • Privacy-focused
    Briar prioritizes user privacy by encrypting all messages end-to-end, ensuring that only the intended recipients can read the content.
  • Decentralized
    The app operates in a decentralized manner, meaning it doesn't rely on a central server, which reduces the risk of censorship and server-based attacks.
  • Peer-to-peer Communication
    Briar uses peer-to-peer communication methods, including Bluetooth, Wi-Fi, and the internet, enabling connectivity even without a central network or in environments with internet censorship.
  • Open-source
    Briar is open-source software, allowing anyone to inspect, modify, and contribute to its codebase, which helps with transparency and trust in the platform.
  • Offline Messaging
    Briar supports offline messaging via Bluetooth and Wi-Fi direct, which is particularly useful in regions with limited internet access.

Possible disadvantages of Briar

  • Limited User Base
    Due to its niche focus on privacy and security, Briar may have a smaller user base compared to more mainstream messaging apps, potentially limiting its network effects.
  • Resource Intensive
    The app can be resource-intensive, consuming more battery and data than traditional messaging apps due to its encryption and peer-to-peer communication methods.
  • Lack of Features
    Briar may lack some of the features found in popular messaging apps, such as media-rich messages, stickers, or integrated services, which might not appeal to all users.
  • Learning Curve
    New users may find the app less intuitive and harder to use compared to mainstream messaging apps, potentially creating a barrier to entry.
  • Android-only
    As of now, Briar is limited to Android devices, which excludes users on other platforms like iOS and may restrict its overall user adoption.

Questions & Answers

As answered by people managing Briar 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.

    Your criticism is fair, however, not everyone keeps their Android phones configured thus.
