This is the official MCP server that connects AI assistants to the Perplexity Search API, providing them with real-time web search, reasoning, and conversational research capabilities.
Security Assessment
The overall risk is rated as Low. The server requires an API key to function, which it securely reads from local environment variables (`process.env`) rather than hardcoding sensitive secrets. It makes necessary outbound network requests to the Perplexity API to fetch search results. The tool does not execute arbitrary shell commands or request dangerous local permissions, limiting its exposure. The standard security consideration applies: users must ensure they do not accidentally expose or leak their API keys in public configurations.
Quality Assessment
The project demonstrates strong quality and reliability. It is officially maintained by Perplexity AI and uses the permissive MIT license. Activity is healthy, with the most recent code push occurring just 22 days ago. With over 2,100 stars on GitHub, it has garnered significant community trust and widespread adoption. The codebase is written in TypeScript, providing excellent type safety and easier automated security auditing compared to untyped languages.
Verdict
Safe to use, provided you follow standard security practices for safeguarding your API key.

Cursor, Claude Desktop, Kiro, Windsurf, and VS Code
Most clients can be configured manually using the same mcpServers wrapper in their client config (as shown for Cursor). If a client has a different schema, check its docs for the exact wrapper format.
For manual setup, these clients all use the same mcpServers structure:
| Client | Config File |
|---|---|
| Cursor | ~/.cursor/mcp.json |
| Claude Desktop | claude_desktop_config.json |
| Kiro | .kiro/settings/mcp.json |
| Windsurf | ~/.codeium/windsurf/mcp_config.json |
| VS Code | .vscode/mcp.json |
{
"mcpServers": {
"perplexity": {
"command": "npx",
"args": ["-y", "@perplexity-ai/mcp-server"],
"env": {
"PERPLEXITY_API_KEY": "your_key_here"
}
}
}

Proxy Setup (For Corporate Networks)
If you are running this server at work—especially behind a company firewall or proxy—you may need to tell the program how to send its internet traffic through your network's proxy. Follow these steps:
1. Get your proxy details
- Ask your IT department for your HTTPS proxy address and port.
- You may also need a username and password.
2. Set the proxy environment variable
The easiest and most reliable way for Perplexity MCP is to use PERPLEXITY_PROXY. For example:
export PERPLEXITY_PROXY=https://your-proxy-host:8080
If your proxy needs a username and password, use:
export PERPLEXITY_PROXY=https://username:password@your-proxy-host:8080
3. Alternate: Standard environment variables
If you'd rather use the standard variables, we support HTTPS_PROXY and HTTP_PROXY.
[!NOTE]
The server checks proxy settings in this order:PERPLEXITY_PROXY→HTTPS_PROXY→HTTP_PROXY. If none are set, it connects directly to the internet.
URLs must includehttps://. Typical ports are8080,3128, and80.
HTTP Server Deployment
For cloud or shared deployments, run the server in HTTP mode.
Environment Variables
| Variable | Description | Default |
|---|---|---|
PERPLEXITY_API_KEY |
Your Perplexity API key | Required |
PERPLEXITY_BASE_URL |
Custom base URL for API requests | https://api.perplexity.ai |
PORT |
HTTP server port | 8080 |
BIND_ADDRESS |
Network interface to bind to | 0.0.0.0 |
ALLOWED_ORIGINS |
CORS origins (comma-separated) | * |
Docker
docker build -t perplexity-mcp-server .
docker run -p 8080:8080 -e PERPLEXITY_API_KEY=your_key_here perplexity-mcp-server
Node.js
export PERPLEXITY_API_KEY=your_key_here
npm install && npm run build && npm run start:http
The server will be accessible at http://localhost:8080/mcp
Troubleshooting
- API Key Issues: Ensure
PERPLEXITY_API_KEYis set correctly - Connection Errors: Check your internet connection and API key validity
- Tool Not Found: Make sure the package is installed and the command path is correct
- Timeout Errors: For very long research queries, set
PERPLEXITY_TIMEOUT_MSto a higher value - Proxy Issues: Verify your
PERPLEXITY_PROXYorHTTPS_PROXYsetup and ensureapi.perplexity.aiisn't blocked by your firewall. - EOF / Initialize Errors: Some strict MCP clients fail because
npxwrites installation messages to stdout. Usenpx -yqinstead ofnpx -yto suppress this output.
