Overview

What is Perplexity MCP Server?

Perplexity MCP Server is a minimalist research server implementing the Model Context Protocol (MCP) to deliver AI-powered research capabilities through Perplexity's web interface. It uses browser automation to perform searches, extract content, and maintain persistent conversations without requiring an API key. It is designed for developers and researchers who need intelligent web research, documentation retrieval, and code analysis.

How to use Perplexity MCP Server?

Install the Bun runtime and Node.js 18+, clone the repository, run bun install and bun run build. Configure your MCP client with the absolute path to the built main.js file and an optional timeout of 300 seconds. Optionally, for Pro account benefits, run bun run login and log in via email. Initiate tasks through your MCP client using natural language commands such as "Use perplexity to research quantum computing advancements" or "Ask perplexity-server for React 18 documentation."

FAQ from Perplexity MCP Server

What does Perplexity MCP Server do differently from traditional APIs?

It requires no authentication or API key – it works through browser automation. It is free, processes data locally, includes native GitHub integration, and stores conversation history in SQLite.

What are the runtime requirements?

Bun runtime and Node.js 18+ (for TypeScript compilation) are required.

How does data privacy work?

All processing is local; conversation history is stored in a local SQLite database. No data is sent to remote servers except through Perplexity’s web interface.

How do I use my Perplexity Pro subscription?

Run bun run login, log in via email (recommended for best compatibility) in the browser window that opens, then close the browser. The session is saved and will be used automatically.

Are there any known limitations?

Stability depends on Perplexity’s website consistency. GitHub paths must use full repository URLs. Link recursion depth can be adjusted in the source configuration. The project is licensed under GNU GPL v3.0.
