    "perplexity-search": {
      "command": "/path/to/perplexity-search-mcp",
      "env": {
        "PERPLEXITY_API_KEY": "your-api-key-here"
      }
    }
  }
}

Docker Support

  1. Build the Docker image:
docker build -t perplexity-search-mcp:latest .
  1. Run the container:
docker run -i --rm -e PERPLEXITY_API_KEY=your-api-key-here perplexity-search-mcp:latest

Example Usage

Once configured, Claude can use the perplexity_search tool via MCP to perform real-time web searches.

Example search with parameters:

{
  "query": "latest AI research developments",
  "search_recency_filter": "week",
  "temperature": 0.5,
  "return_related_questions": true,
  "web_search_options": {
    "search_context_size": "high"
