Perplexity MCP Server

# Perplexity MCP Server This is a simple MCP server that allows you to search the web using Perplexity AI. ## Installation ### Prerequisites - Node.js 18+ (Download from [nodejs.org](https://nodejs.org/)) - Git (Download from [git-scm.com](https://git-scm.com/download/win)) - A Perplexity AI API key ### Steps for Windows 1. Clone the repository: ```bash git clone [repository-url] cd perplexity-mcp-server ``` 2. Install dependencies: ```bash npm install ``` 3. Create environment file: - Create a new file named `.env` in the root directory - Add your Perplexity AI API key: ```env PERPLEXITY_API_KEY=your_api_key_here ``` ## Usage on Windows ### Development Mode ```bash npm run dev ``` ### Production Mode 1. Build the project: ```bash npm run build ``` 2. Start the server: ```bash npm start ``` ### Using the Windows Batch File (Recommended) To avoid environment variable issues on Windows, use the included batch file: 1. Build the project first: ```bash npm run build ``` 2. Run the batch file: ```bash .\run-perplexity-server.bat ``` Alternatively, double-click the `run-perplexity-server.bat` file in Windows Explorer. For detailed instructions, see the [Windows Setup Guide](./docs/windows-setup.md). ## Troubleshooting Windows Issues ### Common Issues 1. **Permission Errors** - Run Command Prompt or PowerShell as Administrator - Check file permissions in the project directory 2. **Environment Variables** - Ensure `.env` file is in the root directory - No spaces around the `=` sign in `.env` file - Restart terminal after making changes to environment variables - Use the provided batch file to avoid environment variable issues 3. **Node.js Issues** - Verify Node.js installation: `node --version` - Ensure npm is installed: `npm --version` ### Error Messages If you see `Error: ENOENT: no such file or directory`, ensure: - All paths use correct Windows-style separators - You're in the correct directory - Required files exist ## Project Structure ``` perplexity-mcp-server/ ├── src/ │ └── index.ts # Main server implementation ├── dist/ # Compiled output ├── .env # Environment variables ├── package.json # Project configuration ├── run-perplexity-server.bat # Windows batch file └── tsconfig.json # TypeScript configuration ``` ## API Usage The server provides a single tool `perplexity_search` for web searches: ```json { "name": "perplexity_search", "arguments": { "query": "your search query here" } } ``` ## License MIT
