Overview

Description from the maker (original English)

Remote MCP server exposing your Node Command fleet (files, shell, processes, browser) to AI hosts.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Docs, sheets & office work

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "nc": {
      "type": "http",
      "url": "https://mcp.nodecommand.app/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker

Menu names can differ slightly by plan and over time.

What it can do

The server asks you to sign in before it lists its tools.

Compared with others in Docs, sheets & office worki

  • More stars than 0% of the other 3544 servers in this category
  • Published to the registry more recently than 69% of the other 3544 servers in this category
  • Basic checks equal to or better than 100% of the other 3544 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is Node Command safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.26.125) reached the registry 14 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

nc-protocol

Public wire contracts, Model Context Protocol (MCP) tool schemas, and agent protocol definitions for Node Command.

This repository is the canonical source of truth for the public Node Command contracts. It contains strictly declarative schemas and contracts: no proprietary server code, no database schemas, and no secrets.

Consumers — the Node Command hub, the nc-agent runtime, and client integrations — vendor this repository at a pinned commit, so contract changes here are explicit and auditable.


Namespaces

agent/     Hub ↔ Agent wire protocol (hello / welcome / request / reply / heartbeat)

mcp/ Canonical authoring definitions and contract manifest policy/ Public host-policy projection + capability names browser/ Public browser and egress policy schemas bindings/ Generated language bindings (JavaScript ESM)


Consuming the contracts

There is no runtime dependency to install: consumers vendor this repository at a pinned commit SHA and import from the vendored tree.

git clone https://github.com/huseyincig/nc-protocol.git

Import the JavaScript bindings directly:

import {

MCP_TOOL_CONTRACT_VERSION, MCP_TOOL_MANIFEST_FINGERPRINT, MCP_TOOL_NAMES, HOST_POLICY_CAPABILITY_NAMES } from './nc-protocol/bindings/javascript/contracts.mjs';

JSON schemas can be imported by path:

import helloSchema from './nc-protocol/agent/hello.schema.json' with { type: 'json' };

import toolsIndex from './nc-protocol/mcp/tools/index.json' with { type: 'json' };

The current contract version, fingerprint, and capability list are pinned in mcp/contract-version, mcp/fingerprint, and policy/capability-names; the current generation and rollout rules are in COMPATIBILITY.md.

The manifest counts canonical authoring definitions, not the number of tools available to a particular connected user. The hosted platform composes these definitions into its public nc_ surface and filters discovery by role and scope. Use that server's authenticated tools/list response for callable names and schemas; do not invoke an authoring identifier merely because it appears here. Internal operation identifiers and the agent wire protocol remain distinct.


Testing & Validation

nc-protocol has zero runtime dependencies and uses the native Node.js test runner:

# Clone the repository

git clone https://github.com/huseyincig/nc-protocol.git cd nc-protocol

Run test suite

npm test

Or:

node --test tests/*.mjs

The test suite validates:

  1. Presence of all required namespace files.
  2. Exact matching between tool definitions, mcp/tools/index.json, and tool count.
  3. Cryptographic consistency of the canonical sha256 manifest fingerprint.
  4. Schema parse validity and schema draft conformance.
  5. Binding parity with declarative contract files.
