🔍 Perplexity AI MCP without API key
This project is a Model Context Protocol (MCP) server that exposes Perplexity AI's search, research, and reasoning capabilities as programmable tools. It operates directly with your Perplexity account session tokens, eliminating the need for a separate paid API key.
