Perplexity MCP Zerver 📋

A research level Model Context Protocol (MCP) server implementation providing AI-powered research capabilities by interacting with the Perplexity website without requiring an API key.

Features

• 🔍 Web search integration via Perplexity's web interface.
• 💬 Persistent chat history for conversational context.
• 📄 Tools for documentation retrieval, API finding, and code analysis.
• 🚫 No API Key required (relies on web interaction).
• 🛠️ TypeScript-first implementation.
• 🌐 Uses Puppeteer for browser automation.

Tools

1. Search (search)

Performs a search query on Perplexity.ai. Supports brief, normal, or detailed responses. Returns raw text output.

2. Get Documentation (get_documentation)

Asks Perplexity to provide documentation and examples for a technology/library, optionally focusing on specific context. Returns raw text output.

3. Find APIs (find_apis)

Asks Perplexity to find and evaluate APIs based on requirements and context. Returns raw text output.

4. Check Deprecated Code (check_deprecated_code)

Asks Perplexity to analyze a code snippet for deprecated features within a specific technology context. Returns raw text output.

5. Extract URL Content (extract_url_content)

Extracts main article text content from URLs using browser automation and Mozilla's Readability. Handles GitHub repositories via gitingest.com. Supports recursive link exploration up to depth. Returns structured JSON with content and metadata.

6. Chat (chat_perplexity)

Maintains ongoing conversations with Perplexity AI. Stores chat history locally in chat_history.db within the project directory. Returns a stringified JSON object containing chat_id and response.

Installation

just copy 📋 and paste the readme and let the AI take care of the rest

1. Clone or download this repository:

git clone https://github.com/wysh3/perplexity-mcp-zerver.git
cd perplexity-mcp-zerver

2. Install dependencies:

npm install

3. Build the server:

npm run build

Important: Ensure you have Node.js installed. Puppeteer will download a compatible browser version if needed during installation. Restart your IDE/Application after building and configuring the project for changes to take effect.

Configuration

Add the server to your MCP configuration file (e.g., cline_mcp_settings.json for the VS Code extension or claude_desktop_config.json for the desktop app).

Important: Replace /path/to/perplexity-mcp-zerver/build/index.js with the absolute path to the built index.js file on your system.

Example for Cline/RooCode Extension:

{
  "mcpServers": {
    "perplexity-server": {
      "command": "node",
      "args": [
        "/full/path/to/your/perplexity-mcp-zerver/build/index.js" // <-- Replace this path! (in case of windows for ex: "C:\\Users\\$USER\\Documents\\Cline\\MCP\\perplexity-mcp-zerver\\build\\index.js"
      ],
      "env": {},
      "disabled": false,
      "alwaysAllow": [],
      "autoApprove": [],
      "timeout": 300
    }
  }
}

Example for Claude Desktop:

{
  "mcpServers": {
    "perplexity-server": {
      "command": "node",
      "args": [
        "/full/path/to/your/perplexity-mcp-zerver/build/index.js" // <-- Replace this path!
      ],
      "env": {},
      "disabled": false,
      "alwaysAllow": []
    }
  }
}

Usage

1. Ensure the server is configured correctly in your MCP settings file.
2. Restart your IDE (like VS Code with the Cline/RooCode extension) or the Claude Desktop application.
3. The MCP client should automatically connect to the server.
4. You can now ask the connected AI assistant (like Claude) to use the tools, e.g.:
   • "Use perplexity-server search to find the latest news on AI."
   • "Ask perplexity-server get_documentation about React hooks."
   • "Start a chat with perplexity-server about quantum computing."
