webos-mcp

An MCP (Model Context Protocol) server that gives Claude deep, persistent knowledge of legacy Palm/HP webOS development — so you don't have to re-teach Claude platform basics every session, and neither does anyone else. This effort compliments the SDK restoration at sdk.webosarchive.org

This covers the original Palm/HP webOS (2009–2012), not LG's webOS TV platform. Maintained in conjunction with the webOS Archive project.

How It Works

Claude needs to be taught webOS once per session — things like how novacom works, what sources.json does, how the Luna service bus operates. Without help, that knowledge disappears when the session ends and has to be re-established the next time.

This package solves that with a two-layer approach:

┌─────────────────────────────────────────────────────┐
│  Layer 1: webos-mcp (this package)                  │
│  Installed once globally. Holds all the curated     │
│  webOS knowledge. Updated centrally via npm.        │
└─────────────────────────────────────────────────────┘
                          +
┌─────────────────────────────────────────────────────┐
│  Layer 2: CLAUDE.md in your project                 │
│  Added once per project. Tells Claude to load the   │
│  MCP knowledge at the start of every session,       │
│  automatically — no slash command to remember.      │
└─────────────────────────────────────────────────────┘

The result: open any webOS project in Claude Code, and Claude already knows the platform. No setup, no /commands to remember, no copy-pasting documentation.

Setup

Step 1 — Install the MCP server (once, globally)

Prerequisites: Node.js 18+, Claude Code CLI

Run this command once — no separate npm install needed:

claude mcp add webos-mcp -s user -- npx -y webos-mcp

The -s user flag registers the server globally (available in every project). The server starts automatically in new Claude Code sessions — you can verify it's connected with claude mcp list.

Running a local clone instead of npx?

claude mcp add webos-mcp -s user -- node /path/to/webos-mcp/index.js

Prefer to edit ~/.claude.json manually? Add this under the top-level mcpServers key:

"webos-mcp": {
  "type": "stdio",
  "command": "npx",
  "args": ["-y", "webos-mcp"],
  "env": {}
}

Step 2 — Add a CLAUDE.md to your webOS project (once per project)

Copy templates/CLAUDE.md from this repo into the root of your webOS app and fill in your project details:

curl -o CLAUDE.md https://raw.githubusercontent.com/webosarchive/webos-mcp/main/templates/CLAUDE.md

Then edit it — set your app ID, framework, target devices, and add any project-specific notes Claude should know.

The key part that makes loading automatic is this section in the template:

## Session Setup

At the start of every session, load the full webOS platform context:

    webos://knowledge/all

When Claude opens your project, it reads CLAUDE.md, sees that instruction, fetches the knowledge bundle from the MCP server, and arrives pre-loaded with webOS context — without you doing anything.

Knowledge Included

All files in knowledge/ are auto-discovered and served as webos://knowledge/<filename>. Load everything at once with webos://knowledge/all, or fetch individual topics as needed mid-session.

Core Platform

UI Frameworks

Services & Backend

System Features

Distribution & Packaging

Networking & Portability

Bundle

Also includes prompts:

• webos-session-start — manually prime Claude with full webOS context
• webos-new-app — scaffold a new Mojo or Enyo app

Developer Experience

Once set up, the flow is:

1. Open your webOS project in Claude Code
2. Claude reads CLAUDE.md → fetches webos://knowledge/all automatically
3. Start working — Claude already knows webOS

You can also load specific topics mid-session:

"Read webos://knowledge/sdk-tools before we continue"

Or manually trigger the session prompt if you're starting a webOS session outside a project:

"Use the webos-session-start prompt"

Project-Level Config (alternative to global)

If you only want the MCP server active for specific webOS projects, register it at project scope instead:

claude mcp add webos-mcp -s project -- npx -y webos-mcp

This writes to .mcp.json in the project root (commit it to share with your team). Team members will be prompted to approve the server the first time they open the project.

Keeping Knowledge Current

The knowledge lives in knowledge/ as plain Markdown files — easy to read, easy to edit, easy to contribute to.

To improve or correct anything:

1. Edit the relevant .md file in knowledge/
2. Submit a PR to webosarchive/webos-mcp
3. When a new version is published to npm, everyone using npx gets it automatically on their next session
