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.

ReqRes features and specs

  • Free and Open Access
    ReqRes is freely accessible, providing developers with a simple way to test APIs without any cost barriers.
  • Comprehensive API Endpoints
    It offers a variety of endpoints for testing HTTP methods like GET, POST, PUT, DELETE, which are commonly used in RESTful APIs.
  • No Authentication Required
    Users can test API calls without needing to go through authentication processes, simplifying testing for quick development cycles.
  • Static Data
    Provides consistent and predictable data for users, enabling reliable testing conditions.
  • Educational Resource
    Serves as a tool for teaching and learning API integration and HTTP methods, useful for beginners.

Possible disadvantages of ReqRes

  • Limited Data Interaction
    ReqRes only uses static data, which might not completely mimic the dynamic nature of real-world APIs.
  • No Custom Data
    You cannot add or modify the dataset; it's predefined, which limits the scope for more extensive testing scenarios.
  • Lack of Authentication Testing
    Due to its simplicity and lack of an authentication mechanism, it's not suitable for testing scenarios that involve user authentication/security.
  • Limited to REST
    ReqRes only supports REST APIs, excluding developers who need to work with SOAP or GraphQL.
  • Not Suitable for Production
    Being a mock API, it's only suitable for development and testing, not for production environments.

Questions & Answers

As answered by people managing ReqRes 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.
