What the code does

We read the source, 8 h ago · rules 3dff92dd89df

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 r = spawnSync(cmd, args, {

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

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

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 passwerk -- npx -y @passwerk/server
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "passwerk": {
      "args": [
        "-y",
        "@passwerk/server"
      ],
      "command": "npx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.passwerk]
command = "npx"
args = ["-y", "@passwerk/server"]
.cursor/mcp.json
{
  "mcpServers": {
    "passwerk": {
      "args": [
        "-y",
        "@passwerk/server"
      ],
      "command": "npx"
    }
  }
}
.vscode/mcp.json

  "mcpServers": {

        "@passwerk/server"
      ],
      "command": "npx"
    }
  }
}

This one needs environment variables set before it will start: PASSWERK_ROOT (Directory ingest_documents may read and emit_passport may write (default: the working directory)), PASSWERK_LOG_LEVEL (info (default) or debug; JSON lines on stderr). The author declared them in the registry entry; get the values from the project itself.

passwerk — questions

Answers built from our own checks of this server.

Why is there no uptime for passwerk?
passwerk 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 @passwerk/server was installed 41 times last week.
How do I connect passwerk?
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 @passwerk/server straight from npm; nothing to host, nothing to sign up for.
How many people use passwerk?
The npm package @passwerk/server was installed 41 times in the last week. Week over week that is +239%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is passwerk open source?
Yes — it is published under the Apache-2.0 licence, written in HTML and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
