Mpx Lsp

sevenlee-claude-code-plugins

A collection of Claude Code plugins providing language server integrations and development tools.

Plugins

Plugin	Description	Version
mpx-lsp	Mpx language server integration for .mpx files	0.1.0

Installation

Install the required language server before installing the Claude Code plugin:

npm install -g @mpxjs/language-server
which mpx-language-server

The mpx-lsp plugin starts the mpx-language-server executable from your PATH, so the second command must print a path. If it does not, make sure your npm global binary directory is included in PATH.

Then make Claude Code aware of this marketplace:

1. Run claude
2. /plugin marketplace add https://github.com/lidongsevenlee/sevenlee-claude-code-plugins

Enable the plugins of your choice:

1. Run claude
2. Type /plugins
3. Tab to Marketplaces
4. Enter the sevenlee-claude-code-plugins marketplace and choose Browse plugins
5. Select the plugins you'd like with the spacebar (e.g. mpx-lsp)
6. Press "i" to install them
7. Restart Claude Code

After restarting, open a project that contains .mpx files. Claude Code should start mpx-language-server automatically for those files.

mpx-lsp

Provides intelligent language features for Mpx.js single-file components in Claude Code.

Features

• Diagnostics and type checking for .mpx files
• TypeScript/JavaScript intellisense
• Go-to-definition, find references, hover
• Auto-completions and code actions

Requirements

• @mpxjs/language-server installed globally, which provides the mpx-language-server command
• mpx-language-server available in PATH
• TypeScript available in your project at node_modules/typescript/lib

Plugin Configuration Reference

The following configuration is bundled inside the mpx-lsp plugin. Users do not need to create or copy this file during installation; it is shown here only for maintainers and troubleshooting.

{
  "mpx": {
    "command": "mpx-language-server",
    "args": ["--stdio"],
    "transport": "stdio",
    "extensionToLanguage": { ".mpx": "mpx" },
    "maxRestarts": 3
  }
}

Troubleshooting

• mpx-language-server: command not found: install @mpxjs/language-server globally and verify which mpx-language-server prints a path.
• The plugin is installed but .mpx files do not get language features: restart Claude Code and reopen the project.
• TypeScript-related errors: run npm install in the Mpx project so local dependencies, including TypeScript, are available.

Contributing

To add a new plugin, create a directory with its .lsp.json config and register it in .claude-plugin/marketplace.json.
