Overview

Description from the maker (original English)

Offline Protocol packages, workflows and integration guides over HTTPS. Read-only.

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: Other
  • You need to fill in: Authorization, x-app-id

Install

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

Before you install

  • Basic checks: 2 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: Authorization, x-app-id

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

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

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http hosted https://mcp.offlineprotocol.com/mcp --header 'Authorization: Bearer {api_key}' --header 'x-app-id: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "hosted": {
      "url": "https://mcp.offlineprotocol.com/mcp",
      "headers": {
        "Authorization": "Bearer {api_key}",
        "x-app-id": "your-value"
      }
    }
  }
}

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": {
    "hosted": {
      "type": "http",
      "url": "https://mcp.offlineprotocol.com/mcp",
      "headers": {
        "Authorization": "Bearer {api_key}",
        "x-app-id": "your-value"
      }
    }
  }
}

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.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • Authorization secret required HTTP header
    Offline Protocol application API key as a bearer token. Organization keys are not accepted.
  • x-app-id required HTTP header
    Application id that owns the API key. It must match the key's application.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

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

Common questions

Is Offline Protocol (hosted) safe?

It passed 2 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?

You need to fill in: Authorization, x-app-id

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 (0.3.2) reached the registry yesterday.

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.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, SSTracker free youth training

README from the maker

Offline Protocol agent plugins

Plugins, skills and MCP configuration that connect coding agents (Claude Code, Codex, Cursor, Gemini CLI, VS Code, Cline, Devin and other MCP clients) to the Offline Protocol developer tools. Your agent can find Offline Protocol SDK packages, read integration guides and workflows, plan an implementation, and scaffold or integrate a project on your machine.

Every configuration runs the local MCP server from the published Offline Protocol CLI, npx -y @offline-protocol/cli@0.3.2 mcp serve, or connects to the hosted MCP server at https://mcp.offlineprotocol.com/mcp. The tools help you build an application. They do not discover nearby devices, operate a mesh or control live hardware.

  • Documentation: https://www.offlineprotocol.com/docs/tools/overview
  • npm package: https://www.npmjs.com/package/@offline-protocol/cli

This repository is generated from the Offline Protocol CLI source by its export-agent-plugins.mjs script. SOURCE.json records the source commit and a sha256 for every file. Changes are made in the source and exported here; pull requests to this repository are reviewed and applied upstream.

Requirements

Node.js 18 or later with npx. The first run downloads the pinned CLI (@offline-protocol/cli@0.3.2) from npm. Local tools need no Offline Protocol account and send no telemetry. The hosted server needs an application API key and its application ID from https://dev.offlineprotocol.com.

Install

Claude Code plugin
claude plugin marketplace add https://github.com/Offline-Protocol/offline-protocol-agent-plugins.git

claude plugin install offline-protocol@offline-protocol

Codex
codex plugin marketplace add https://github.com/Offline-Protocol/offline-protocol-agent-plugins.git

codex plugin add offline-protocol@offline-protocol

Or add only the MCP server:

codex mcp add offline-protocol -- npx -y @offline-protocol/cli@0.3.2 mcp serve
Cursor

Copy plugins/offline-protocol into ~/.cursor/plugins/local/offline-protocol and reload Cursor. For the MCP server alone, put the contents of distribution/clients/mcp-stdio.json in .cursor/mcp.json or ~/.cursor/mcp.json, or use the install link in distribution/clients/README.md.

Gemini CLI extension

The repository root is a Gemini CLI extension (gemini-extension.json).

gemini extensions install https://github.com/Offline-Protocol/offline-protocol-agent-plugins
VS Code with GitHub Copilot
code --add-mcp '{"name":"offline-protocol","type":"stdio","command":"npx","args":["-y","@offline-protocol/cli@0.3.2","mcp","serve"]}'

For one workspace, copy distribution/clients/vscode.json to .vscode/mcp.json.

Cline
cline mcp install offline-protocol -- npx -y @offline-protocol/cli@0.3.2 mcp serve
Devin

Devin CLI:

devin plugins install Offline-Protocol/offline-protocol-agent-plugins#plugins/offline-protocol

Devin (web): add a custom MCP server with transport stdio, command npx and arguments -y @offline-protocol/cli@0.3.2 mcp serve. Devin Desktop: distribution/clients/devin-desktop.json.

Any other MCP client

Use this server definition (also in distribution/clients/mcp-stdio.json):

{

"mcpServers": { "offline-protocol": { "command": "npx", "args": ["-y", "@offline-protocol/cli@0.3.2", "mcp", "serve"] } } }

Zed, Continue, xAI and hosted configurations are in distribution/clients/README.md and distribution/clients/priority-two.md.
