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.

Foam features and specs

  • Open Source
    Foam is an open-source tool, which means it is free to use and allows for community-driven development and contributions. Users can modify the source code to fit their specific needs.
  • Markdown Support
    Foam uses Markdown, a lightweight and easy-to-read syntax, making it simple to create and manage notes. This also allows for easy integration with other Markdown-based tools and platforms.
  • Integration with Visual Studio Code
    Foam is designed to work seamlessly with Visual Studio Code (VS Code). This provides users with a powerful and familiar text editor environment, complete with extensions and customization options.
  • Graph View
    Foam includes a graph visualization feature that helps users see and navigate the relationships between their notes, making it easier to understand and manage complex information.
  • Bidirectional Links
    Foam supports bidirectional links, allowing users to create connections between notes in both directions. This enhances the note-taking experience by enabling a more interconnected and dynamic information structure.
  • Community and Documentation
    Foam has a growing community of users and contributors, as well as comprehensive documentation. This support network helps users troubleshoot issues, share tips, and improve their knowledge of the tool.

Possible disadvantages of Foam

  • Limited to VS Code
    Foam relies on Visual Studio Code as its primary environment. Users who prefer different text editors or platforms might find this limitation restrictive and less convenient.
  • Learning Curve
    Although Foam leverages Markdown, users may still face a learning curve, especially if they are not familiar with VS Code or the specific features and extensions required to maximize Foam's capabilities.
  • Performance with Large Datasets
    Foam can struggle with performance issues when handling large datasets or a high number of notes. This can lead to slow response times and inefficient workflows.
  • Limited Mobile Support
    Foam is primarily designed for desktop use within VS Code, which means that mobile support is limited. Users looking for a seamless cross-platform experience might find this aspect lacking.
  • Customization Complexity
    While Foam offers a high degree of customization, setting up and configuring the tool to meet personal preferences and workflows can be complex and time-consuming for some users.

Questions & Answers

As answered by people managing Foam 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.

  • AI Coding Tip 020 - Create a Second Brain
    Choose a local Markdown tool like Obsidian, Logseq, Foam, or Tolaria to store all your knowledge as plain .md files you own and control. - Source: dev.to / 2 months ago
  • Migrating from DokuWiki to Obsidian
    I've been using foam instead of obsidian for my personal knowledge base. It works rather well. And it's completely free and ultimately just markdown.

  • I Use Obsidian
    I gave up on Obsidian and just use Foam (https://foambubble.github.io/foam/) and/or vimwiki. I just canโ€™t get into overwrought, arbitrarily designed organization schemes or proprietary apps (Foam-managed content is just plain Markdown, so I can easily do without itโ€”it provides the absolute bare minimum for easy linking of notes without proprietary markup). - Source: Hacker News / about 2 years ago
