MCP Servers Reference

Think of MCP servers as power tools that plug into Claude Code. Need the latest framework docs without leaving your terminal? That's Context7. The plugin bundles it—it just works when you install.

Known Issue: Auto-Loading

Sometimes MCP servers don't wake up automatically. If Claude can't take screenshots or look up docs, you'll need to add them manually. See Manual Configuration for the fix.

Manual Configuration

If the servers don't load automatically (you'll know because Claude can't take screenshots or fetch docs), you need to wire them up yourself. It's a two-minute copy-paste job.

Project-Level Configuration

To enable for just this project, add this to .claude/settings.json in your project root:

{
  "mcpServers": {
    "context7": {
      "type": "http",
      "url": "https://mcp.context7.com/mcp"
    }
  }
}

Global Configuration

Or enable everywhere—every project on your machine gets these servers. Add to ~/.claude/settings.json:

{
  "mcpServers": {
    "context7": {
      "type": "http",
      "url": "https://mcp.context7.com/mcp"
    }
  }
}

Requirements

Server	Requirement
Context7	Internet connection (HTTP endpoint)

Verifying MCP Servers

After you add the config, restart Claude Code. Then test that everything works:

# Ask Claude what it has
"What MCP tools do you have access to?"

# Test Context7 (should fetch real docs)
"Look up Rails Active Record documentation"

# If either fails, double-check your JSON syntax and file paths
