MCP Servers

Server	Description
context7	Framework documentation lookup via Context7

Context7

Tools provided:

• resolve-library-id - Find library ID for a framework/package
• get-library-docs - Get documentation for a specific library

Supports 100+ frameworks including Rails, React, Next.js, Vue, Django, Laravel, and more.

MCP servers start automatically when the plugin is enabled.

Authentication: To avoid anonymous rate limits, set the CONTEXT7_API_KEY environment variable with your Context7 API key. The plugin passes this automatically via the x-api-key header. Without it, requests go unauthenticated and will quickly hit the anonymous quota limit.

Browser Automation

This plugin uses agent-browser CLI for browser automation tasks. Install it globally:

npm install -g agent-browser
agent-browser install  # Downloads Chromium

The agent-browser skill provides comprehensive documentation on usage.

Installation

claude /plugin install compound-engineering

Known Issues

MCP Servers Not Auto-Loading

Issue: The bundled Context7 MCP server may not load automatically when the plugin is installed.

Workaround: Manually add it to your project's .claude/settings.json:

{
  "mcpServers": {
    "context7": {
      "type": "http",
      "url": "https://mcp.context7.com/mcp",
      "headers": {
        "x-api-key": "${CONTEXT7_API_KEY:-}"
      }
    }
  }
}

Set CONTEXT7_API_KEY in your environment to authenticate. Or add it globally in ~/.claude/settings.json for all projects.
