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.

Onionshare features and specs

  • Anonymity
    Onionshare allows users to share files without revealing their identity, thanks to the Tor network.
  • End-to-End Encryption
    All files transferred using Onionshare are encrypted end-to-end, ensuring secure data transmission.
  • No File Size Limits
    Unlike many file-sharing services, Onionshare does not impose file size limits, making it suitable for sharing large files.
  • Open Source
    The software is open-source, allowing transparency and community-driven development. Users can review the code for security and trustworthiness.
  • No Third-Party Servers
    Files are shared directly between users without passing through third-party servers, eliminating risks associated with centralized server breaches.

Possible disadvantages of Onionshare

  • Dependency on Tor
    Requires the Tor network to function, meaning users need to install and configure Tor, which could be challenging for non-technical users.
  • Speed Limitations
    Data transfer speeds are limited by the Tor network's performance, which can be slower compared to traditional file-sharing services.
  • Temporary Links
    Sharing links are temporary and can expire, which may not be ideal for long-term sharing or collaboration.
  • Usability
    The user interface might not be as intuitive or user-friendly as other mainstream file-sharing applications.
  • Limited Features
    Onionshare is primarily focused on secure file sharing and does not offer additional features like collaborative editing or cloud storage.

Questions & Answers

As answered by people managing Onionshare 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.
