Add Fetch (Reference)

Install / run

uvx mcp-server-fetch

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "fetch-reference": {
      "command": "uvx",
      "args": [
        "mcp-server-fetch"
      ]
    }

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

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