Verdict

Pick DuckDuckGo Search if you want zero-setup with no API key.

Pick Perplexity if you want the official, vendor-maintained server, and you prefer the more popular, battle-tested option.

Add DuckDuckGo Search

Install / run

uvx duckduckgo-mcp-server

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

{
  "mcpServers": {
    "duckduckgo-search": {
      "command": "uvx",
      "args": [
        "duckduckgo-mcp-server"
      ]
    }
  }
}

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

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>"
