Installation

Prerequisites

Node.js 18+
npx available in PATH

Global Configuration

MCP servers are configured in your Claude Code settings:

Location: ~/.claude/settings.json (user) or .claude/settings.json (project)

Quick Setup

Copy the desired configuration from the server-specific JSON files
Add to your settings.json under mcpServers
Restart Claude Code

Server Configurations

Context7 (Documentation Lookup)

Provides up-to-date documentation for libraries and frameworks.

{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": ["-y", "@context7/mcp-server"]
    }
  }
}

Usage: Ask about any library and get current documentation.

Sequential Thinking

Provides structured reasoning tools for complex problem-solving.

{
  "mcpServers": {
    "sequential": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-sequential-thinking"]
    }
  }
}

Usage: Complex analysis with step-by-step reasoning.

Puppeteer (Browser Automation)

Enables browser automation for testing and web interaction.

{
  "mcpServers": {
    "puppeteer": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-puppeteer"]
    }
  }
}

Usage: Web testing, screenshots, form automation.

Magic (UI Generation)

Generates UI components from descriptions.

{
  "mcpServers": {
    "magic": {
      "command": "npx",
      "args": ["-y", "@anthropic/magic-mcp-server"]
    }
  }
}

Usage: Generate React/Vue components from descriptions.

Full Configuration Example

{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": ["-y", "@context7/mcp-server"]
    },
    "sequential": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-sequential-thinking"]
    },
    "puppeteer": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-puppeteer"]
    }
  }
}

Verification

After configuration, verify servers are loaded:

Start a new Claude Code session
Check for MCP tools in available capabilities
Test with a simple request

Troubleshooting

Server Not Loading

Check Node.js version (18+ required)
Verify npx is in PATH
Check for typos in configuration
Review Claude Code logs

Permission Errors

Ensure network access for package installation
Check firewall settings
Verify npm registry access

Slow Startup

First run downloads packages (one-time)
Subsequent starts should be faster
Consider pre-installing packages globally

Security Notes

MCP servers run with your user permissions
Review server source before installing
Puppeteer has browser access - use carefully
Context7 makes network requests to documentation sources
