Perplexity Ask MCP Server

Perplexity API Platform MCP Server

The official MCP server implementation for the Perplexity API Platform, providing AI assistants with real-time web search, reasoning, and research capabilities through Sonar models and the Search API.

Available Tools

perplexity_search

Direct web search using the Perplexity Search API. Returns ranked search results with metadata, perfect for finding current information.

perplexity_ask

General-purpose conversational AI with real-time web search using the sonar-pro model. Great for quick questions and everyday searches.

perplexity_research

Deep, comprehensive research using the sonar-deep-research model. Ideal for thorough analysis and detailed reports.

perplexity_reason

Advanced reasoning and problem-solving using the sonar-reasoning-pro model. Perfect for complex analytical tasks.

[!TIP] Available as an optional parameter for perplexity_reason and perplexity_research: strip_thinking

Set to true to remove <think>...</think> tags from the response, saving context tokens. Default: false

Configuration

Get Your API Key

• Get your Perplexity API Key from the API Portal

• Replace your_key_here in the configurations below with your API key

• (Optional) Set timeout: PERPLEXITY_TIMEOUT_MS=600000 (default: 5 minutes)

• (Optional) Set custom base URL: PERPLEXITY_BASE_URL=https://your-custom-url.com (default: https://api.perplexity.ai)

• (Optional) Set log level: PERPLEXITY_LOG_LEVEL=DEBUG|INFO|WARN|ERROR (default: ERROR)

Claude Code

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 include https://. Typical ports are 8080, 3128, and 80.

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. Defaults to loopback. Set to 0.0.0.0 to expose on all interfaces. 127.0.0.1 ALLOWED_ORIGINS CORS origins (comma-separated). Defaults to empty (no cross-origin browser requests). Set to an explicit allowlist (e.g. https://app.example.com) or to * to allow any origin. (empty) ALLOWED_HOSTS Additional Host header values to accept (comma-separated). Loopback hosts on PORT are always allowed. Add the public hostname when binding to 0.0.0.0. (loopback only)

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_KEY is 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_MS to a higher value

• Proxy Issues: Verify your PERPLEXITY_PROXY or HTTPS_PROXY setup and ensure api.perplexity.ai isn't blocked by your firewall.

• EOF / Initialize Errors: Some strict MCP clients fail because npx writes installation messages to stdout. Use npx -yq instead of npx -y to suppress this output.
