Perplexity MCP Zerver

A minimalist research server implementing the Model Context Protocol (MCP) to deliver AI-powered research capabilities through Perplexity's web interface.

Research Capabilities

• Intelligent Web Research: Search and summarize content without API limits
• Persistent Conversations: Maintain context with local SQLite chat storage
• Content Extraction: Clean article extraction with GitHub repository parsing
• Developer Tooling: Documentation retrieval, API discovery, code analysis
• Keyless Operation: Browser automation replaces API key requirements

Getting Started

Prerequisites

• Bun runtime
• Node.js 18+ (for TypeScript compilation)

Installation

git clone https://github.com/wysh3/perplexity-mcp-zerver.git
cd perplexity-mcp-zerver
bun install
bun run build

Configuration

Add to your MCP configuration file:

{
  "mcpServers": {
    "perplexity-server": {
      "command": "bun",
      "args": ["/absolute/path/to/build/main.js"],
      "timeout": 300
    }
  }
}

Usage

Initiate commands through your MCP client:

• "Use perplexity to research quantum computing advancements"
• "Ask perplexity-server for React 18 documentation"
• "Begin conversation with perplexity about neural networks"

🔐 Pro Account Support (Optional)

Use your Perplexity Pro subscription for access to better models (GPT-5.1, Claude Sonnet 4.5) and higher limits.

One-Time Setup

bun run build
bun run login

A browser window will open. Log in using email (recommended for best compatibility), then close the browser. Your session is now saved!

> Note: Google/SSO login may work but email login is more reliable with the browser automation.

Troubleshooting

Server Connection Issues

1. Verify absolute path in configuration

2. Confirm Node.js installation with `node -v`

3. Ensure build completed successfully

Content Extraction

• GitHub paths must use full repository URLs
• Adjust link recursion depth in source configuration
