01 · Install Cygnus SSH MCP

before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add cygnussystems-cygnus-ssh-mcp -- uvx cygnus-ssh-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "cygnussystems-cygnus-ssh-mcp": {
      "command": "uvx",
      "args": [
        "cygnus-ssh-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license GPL-3.0 - declared in the repository

pypi package cygnus-ssh-mcp - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.cygnussystems is GitHub-verified and matches the repo owner

Limitations (from the README)

[!WARNING] Alternate-platform (flex) support is a work in progress. It's been verified against several real devices, but the space of routers/NAS/embedded systems is huge - expect rough edges on hardware that hasn't been tried yet.
