🚀 Getting Started with Installation

Install Perplexity MCP Server

1. Claude Desktop Configuration: For macOS, modify your claude_desktop_config.json file as follows:

   "mcpServers": {
     "Perplexity": {
       "command": "uvx",
       "args": [
         "mcp-server-perplexity"
       ],
       "env": {
         "PERPLEXITY_API_KEY": "your-perplexity-api-key"
       }
     }
   }
   

2. Windows Configuration: Similarly, update your claude_desktop_config.json file on Windows:

   "mcpServers": {
     "Perplexity": {
       "command": "uvx",
       "args": [
         "mcp-server-perplexity"
       ],
       "env": {
         "PERPLEXITY_API_KEY": "your-perplexity-api-key"
       }
     }
   }
   

Follow these steps to configure your MCP client to work with the Perplexity MCP Server.

💡 Key Use Cases in AI Workflows
