Keyoxide logo Keyoxide

Keyoxide is a secure platform that allows you to manage a decentralized identity based on cryptographic keys.

Emisar.dev logo Emisar.dev

One governed MCP server connects any AI agent to a finite action catalog, enforced on-host with pack trust, policy gates, human approvals, and a hash-chained audit trail.

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.

Keyoxide features and specs

  • Decentralization
    Keyoxide operates on a decentralized infrastructure, meaning it doesn't rely on a single server or authority. This enhances its security and makes it resilient against single points of failure.
  • Privacy
    Keyoxide does not require users to provide personal information. It leverages cryptographic keys to validate identities, thus maintaining user privacy.
  • Interoperability
    Keyoxide is built on OpenPGP, which is widely supported. This enhances its interoperability with other systems and services that use the same protocol.
  • Transparency
    The platform is open-source, allowing users to inspect the code to ensure there are no backdoors or malicious functionalities. This transparency builds trust within the community.
  • Self-Sovereignty
    Users have full control over their identities and data. They are not dependent on third-party services to manage or authenticate their identities.

Possible disadvantages of Keyoxide

  • Complexity
    For non-technical users, the process of setting up and managing cryptographic keys can be complex and intimidating. This can be a barrier to widespread adoption.
  • Limited Adoption
    Despite its advantages, Keyoxide is not as widely adopted as some centralized identity verification systems. This can limit its usefulness in some contexts.
  • Reliance on OpenPGP
    Keyoxide's effectiveness depends on the security and reliability of the OpenPGP protocol. Any vulnerabilities in OpenPGP could potentially impact Keyoxide.
  • Lack of Third-Party Integration
    As a newer or less mainstream service, Keyoxide may have fewer integrations with other platforms and services compared to more established identity verification systems.
  • No Recovery Mechanism
    If a user loses their cryptographic keys, there is no straightforward recovery mechanism, which could result in the permanent loss of their digital identity.

Questions & Answers

As answered by people managing Keyoxide 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.

  • I have to give Fortnite my passport to use Bluesky
    Although I enjoy the public key/private key ideas, If you wish to talk encrypted, one of the best ways to do such could be having signal if you don't mind centralization But if you want decentralization some options I can recommend are matrix,simplex,session etc. But to be honest, there is a good point that you raise about how to talk decentralized on bluesky well, one of the ideas that I can think of right now,... - Source: Hacker News / 7 months ago

  • A New Form of Verification on Bluesky
    I feel like keybase was a good idea but needs to be redone. I guess there's keyoxide (any other?). What are people's thoughts on that? https://keyoxide.org/. - Source: Hacker News / over 1 year ago
  • Removing PGP from PyPI
    There is Keyoxide[1]. The goal is similar to Keybase (online identify proofs), but Keyoxide uses a decentralized approach where the identity proofs are stored on the key themselves. [1] https://keyoxide.org. - Source: Hacker News / almost 2 years ago
