Perplexity MCP Server

MCP Server for the Perplexity API.

Components

Tools

• ask_perplexity: Request expert programming assistance through Perplexity. Focuses on coding solutions, error debugging, and technical explanations. Returns responses with source citations and alternative suggestions.
• chat_perplexity: Maintains ongoing conversations with Perplexity AI. Creates new chats or continues existing ones with full history context. Returns chat ID for future continuation.

Key Features

• Model Configuration via Environment Variable: Allows you to specify the Perplexity model using the PERPLEXITY_MODEL environment variable for flexible model selection.

  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. You can check which models are available on the Perplexity documentation.

• Persistent Chat History: The chat_perplexity tool maintains ongoing conversations with Perplexity AI. Creates new chats or continues existing ones with full history context. Returns chat ID for future continuation.

• Streaming Responses with Progress Reporting: Uses progress reporting to prevent timeouts on slow responses.
