What the code does

We read the source, 10 min 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.

Runs a command on install [пакет] package.json:1
postinstall: chmod +x dist/agent.js dist/index.js 2>/dev/null || true
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.

Runs an external command installer/onboard.py:16
    subprocess.check_call([sys.executable, "-m", "pip", "install", "cryptography", "--quiet"])
Runs an external command src/exec.ts:218
    const result = spawnSync(command, {
Touches key and credential files src/server.ts:293, src/templates.ts:128
                ssh_key: { type: 'string', description: 'Path to SSH private key on disk (e.g. ~/.ssh/id_ed25519). Prefer ssh_key_entry_id.' },
Dumps the whole environment src/exec.ts:161
    Object.entries(process.env)

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

        "@wundervault/mcp-server"
      ],
      "command": "npx"
    }
  }
}

This one needs environment variables set before it will start: WUNDERVAULT_AGENT_NAME (Agent name registered with the local wundervault-agent daemon (run onboard.py to register).), WUNDERVAULT_AGENT_TOKEN (Optional daemon auth token. Defaults to ~/.wundervault/agents/<agentName>.token.). The author declared them in the registry entry; get the values from the project itself.

Wundervault MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Wundervault MCP?
Wundervault MCP 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 @wundervault/mcp-server was installed 339 times last week.
How do I connect Wundervault MCP?
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 @wundervault/mcp-server straight from npm; nothing to host, nothing to sign up for.
How many people use Wundervault MCP?
The npm package @wundervault/mcp-server was installed 339 times in the last week. Week over week that is +859%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Wundervault MCP open source?
Yes — it is published under the AGPL-3.0 licence, written in TypeScript and 2 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.
