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.

2FAS features and specs

  • Enhanced Security
    2FA Authenticator adds an extra layer of security by requiring a second form of verification, making it harder for unauthorized users to access your accounts.
  • User-Friendly Interface
    The application features a straightforward and intuitive interface, making it easy for users to add and manage their accounts and authentication tokens.
  • Offline Access
    2FA Authenticator works offline, allowing users to generate authentication codes without an Internet connection, which is particularly useful in low-connectivity situations.
  • Cross-Platform Compatibility
    The app is available on multiple platforms, enabling users to sync their accounts and access their authentication codes from various devices.

Possible disadvantages of 2FAS

  • Device Dependency
    Losing access to the device with the 2FA Authenticator can lock users out of accounts, necessitating backup strategies like printing codes.
  • Potential for Misconfiguration
    If not set up correctly, there is a risk of misconfiguration that can lead to being locked out of accounts or decreased security.
  • Initial Setup Complexity
    For some users, the initial setup and configuration of two-factor authentication might be confusing or time-consuming.
  • Limited Recovery Options
    In cases where users lose their authentication device, recovery options might be limited, causing potential inconvenience or the need for support.

Questions & Answers

As answered by people managing 2FAS 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.

  • Playing with more user-friendly methods for multi-factor authentication
    FWIW 2FAS starts to show you the next code near the end of the window, this is very handy https://2fas.com/. - Source: Hacker News / about 1 year ago
  • Bitwarden Authenticator
    I personally switched to using 2FAS[0]. My favorite feature is that it comes with a browser extension that can automatically fill in the OTP on web forms, after approving the request on the phone app. [0] https://2fas.com/. - Source: Hacker News / over 1 year ago
  • Ask HN: AWS registering MFA will be required in 29 days
    I'd go with number 2 unless you want to buy everyone a hardware token (option number 3). There are open source solutions (I've used https://2fas.com/ ) and very common solutions (Google Authenticator). You can even print out the QR code and put it in a secure location (safe, safe deposit box) as a break-glass in case everyone's phones cease functioning. - Source: Hacker News / almost 2 years ago
  • Flaw has Microsoft Authenticator overwriting MFA accounts, locking users out
    Try 2FAS - it works without an cloud account, can import from few other apps (sadly not from Microsoft one) and can export from and import to a file. Works on Android and iOS https://2fas.com/. - Source: Hacker News / almost 2 years ago
  • Ente Auth: open-source Authy alternative for 2FA
