What the code does

We read the source, 20 h ago · rules 3dff92dd89df

Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

    const child = spawn(cmd, cmdArgs, { stdio: 'ignore', detached: true })

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

We found things in this code

Code changes quietly between releases, and nobody reads the diff of a dependency. We do, on every release — watch Shellward and you get told the day something new turns up.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add shellward -- npx -y shellward
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "shellward": {
      "args": [
        "-y",
        "shellward"
      ],
      "command": "npx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.shellward]
command = "npx"
args = ["-y", "shellward"]
.cursor/mcp.json
{
  "mcpServers": {
    "shellward": {
      "args": [
        "-y",
        "shellward"
      ],
      "command": "npx"
    }
  }
}
.vscode/mcp.json
{
  "mcpServers": {

        "-y",
        "shellward"
      ],
      "command": "npx"
    }
  }
}

This one needs environment variables set before it will start: SHELLWARD_MODE (Security mode: enforce (block + log) or audit (log only)), SHELLWARD_LOCALE (Locale: auto, zh, or en), SHELLWARD_THRESHOLD (Injection detection threshold 0-100 (lower = stricter)). The author declared them in the registry entry; get the values from the project itself.

Shellward — questions

Answers built from our own checks of this server.

Why is there no uptime for Shellward?
Shellward runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package shellward was installed 235 times last week.
How do I connect Shellward?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls shellward straight from npm; nothing to host, nothing to sign up for.
How many people use Shellward?
The npm package shellward was installed 235 times in the last week. Week over week that is -61%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Shellward open source?
Yes — it is published under the Apache-2.0 licence, written in TypeScript, 135 stars on GitHub and 4 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
