You can also specify PERPLEXITY_MODEL_ASK and PERPLEXITY_MODEL_CHAT to use different models for the ask_perplexity and chat_perplexity tools, respectively. These will override PERPLEXITY_MODEL.

Configure your MCP Client

To use this MCP server, you need to configure your MCP client to connect to it. The configuration method will vary depending on your specific client.

Below is an example configuration in JSON format:

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

Important notes:

• Replace "your-perplexity-api-key" with your actual Perplexity API key.
• The "PERPLEXITY_MODEL": "sonar-pro" line is optional. If you omit it, the server will use the default Perplexity model.
• You can also set PERPLEXITY_MODEL_ASK and PERPLEXITY_MODEL_CHAT to override PERPLEXITY_MODEL for the individual tools.
• Consult your MCP client's documentation for details on where to place this configuration and any client-specific settings.
• Use the mcp-server-starter script to easily start the server.
