Ncp MCP Server

What the code does

We read the source, 18 h ago · rules 3dff92dd89df

A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

      writeFileSync(tempFile, job.parameters.code, 'utf-8');

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.

const hasNcpEnvVars = Object.keys(process.env).some(key => key.startsWith('NCP_'));

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.

postinstall: npm run build:if-dev

            execSync(`which ${ed}`, { stdio: 'ignore' });

          const destFile = path.join(photonDir, fileName);

      `Update with: ${chalk.cyan(`ncp update ${mcpInfo.name}`)}`

const hasNcpEnvVars = Object.keys(process.env).some(key => key.startsWith('NCP_'));

      const files = await fs.readdir(photonDir);

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.

claude mcp add ncp -- npx -y @portel/ncp

{
  "mcpServers": {
    "ncp": {
      "args": [
        "-y",
        "@portel/ncp"
      ],
      "command": "npx"
    }
  }
}

[mcp_servers.ncp]
command = "npx"
args = ["-y", "@portel/ncp"]

{
  "mcpServers": {
    "ncp": {
      "args": [
        "-y",
        "@portel/ncp"

      "command": "npx"
    }

This one needs environment variables set before it will start: NCP_DEBUG (Enable debug logging for troubleshooting), NCP_MODE (Operating mode: 'mcp' for AI assistant integration or 'cli' for command-line), NO_COLOR (Disable colored output in logs and CLI). The author declared them in the registry entry; get the values from the project itself.
