perplexity
Real-time web search, reasoning, and research through Perplexity's API
Summary
The Perplexity skill enables real-time web search, reasoning, and research through Perplexity's API, allowing Claude Code to fetch up-to-date information, verify facts, and synthesize answers from live sources.
- It's ideal for developers who need current data, citations, or deep research without leaving their coding environment.
Overview
   
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_thinkingSet to
trueto 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_herein 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:

Claude 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 |

}
}

}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:8080If your proxy needs a username and password, use:
export PERPLEXITY_PROXY=https://username:password@your-proxy-host:80803. 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 are8080,3128, and80.
HTTP Server Deployment
For cloud or shared deployments, run the server in HTTP mode.
| 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 build -t perplexity-mcp-server .
docker run -p 8080:8080 -e PERPLEXITY_API_KEY=your_key_here perplexity-mcp-serverexport PERPLEXITY_API_KEY=your_key_here
npm install && npm run build && npm run start:httpThe 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.
