Offline Protocol

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/[email protected] 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.

• 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/[email protected]) 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/[email protected] 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/[email protected]","mcp","serve"]}'

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

Cline

cline mcp install offline-protocol -- npx -y @offline-protocol/[email protected] 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/[email protected] 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/[email protected]", "mcp", "serve"]
    }
  }
}

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