Perplexity MCP Server

What is Perplexity MCP Server?

An MCP (Model Context Protocol) server providing comprehensive access to the Perplexity AI API. It enables LLMs and AI agents to perform fast, search-augmented queries and conduct exhaustive, multi-source deep research through a standardized, secure, and easy-to-integrate protocol. It is built for developers using MCP clients like advanced AI assistants, IDE extensions, or custom research tools.

How to use Perplexity MCP Server?

Install Node.js ≥18 and obtain a Perplexity API key. Clone the repository, run npm install and npm run build. Create a .env file with PERPLEXITY_API_KEY. Configure your MCP client (e.g., Cline) to run the server with the command node /path/to/dist/index.js and pass the environment variable. Start the server with npm start (uses stdio by default) or configure HTTP transport.
