Verdict

Pick Perplexity if you prefer its approach (official perplexity mcp server — web search, ask, deep research, and reasoning via sonar models).

Pick Fetch (Reference) if you prefer the more popular, battle-tested option, and you want zero-setup with no API key.

Add Perplexity

Install / run

npx -y @perplexity-ai/mcp-server

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

{
  "mcpServers": {
    "perplexity": {
      "command": "npx",
      "args": [
        "-y",
        "@perplexity-ai/mcp-server"
      ],
      "env": {
        "PERPLEXITY_API_KEY": "<your-perplexity-api-key>"
      }
    }
  }
}

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"
      ]
    }
  }
}

Requires `uv` (the Python package runner). Install it from https://docs.astral.sh/uv/ if `uvx` is not found.
