Overview

What is Perplexity Sonar MCP Server?

An MCP server implementation that brings Perplexity’s Sonar models to Claude Desktop and other MCP clients. It enables real-time web search during conversations, giving Claude access to current information from the web.

How to use Perplexity Sonar MCP Server?

Configure Claude Desktop by editing claude_desktop_config.json with the npx command and your Perplexity API key as an environment variable. Alternatively, run in standalone mode with PERPLEXITY_API_KEY=your_key perplexity-sonar-mcp on port 3000 (or a custom PORT). The server exposes a single perplexity-chat tool with extensive parameters.

Key features of Perplexity Sonar MCP Server

  • Real-time web search during conversations
  • Multiple Sonar models for different needs
  • Rich parameter control (domains, recency, temperature, etc.)
  • Native integration with Claude Desktop
  • Standalone HTTP/SSE mode for other clients
  • Supports images and related questions in responses

Use cases of Perplexity Sonar MCP Server

  • Ask Claude for the latest news or developments on any topic
  • Perform in-depth research with comprehensive citations using sonar-deep-research
  • Limit search results to specific websites for authoritative sources
  • Filter results by recency (day, week, month) to get timely information
  • Generate creative or focused answers by adjusting temperature and parameters

FAQ from Perplexity Sonar MCP Server

Which models are available?

The server supports sonar (general), sonar-pro (enhanced), sonar-reasoning (logical analysis), and sonar-deep-research (in-depth with citations).

What are the requirements?

Node.js 18.0.0 or higher and a Perplexity API key from https://www.perplexity.ai/account/api.

How do I configure it for Claude Desktop?

Add the configuration to your Claude Desktop config file (~/Library/Application Support/Claude/claude_desktop_config.json on macOS, %APPDATA%\Claude\claude_desktop_config.json on Windows) with the npx -y @felores/perplexity-sonar-mcp command and PERPLEXITY_API_KEY environment variable.

Where can I find logs if something goes wrong?

On macOS, check ~/Library/Logs/Claude/mcp.log; on Windows, check %APPDATA%\Claude\logs\mcp.log.

Can I run the server standalone without Claude Desktop?

Yes, by setting the PERPLEXITY_API_KEY environment variable and running perplexity-sonar-mcp (or npx @felores/perplexity-sonar-mcp). It starts an HTTP/SSE server on port 3000 by default.
