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
1. Get your Perplexity API Key from the [API Portal](https://www.perplexity.ai/account/api/group)
2. Replace `your_key_here` in the configurations below with your API key
3. (Optional) Set timeout: `PERPLEXITY_TIMEOUT_MS=600000` (default: 5 minutes)
4. (Optional) Set log level: `PERPLEXITY_LOG_LEVEL=DEBUG|INFO|WARN|ERROR` (default: ERROR)
### Claude Code
```bash
claude mcp add perplexity --env PERPLEXITY_API_KEY="your_key_here" -- npx -y @perplexity-ai/mcp-server
```
Or install via plugin:
```bash
export PERPLEXITY_API_KEY="your_key_here"
claude
# Then run: /plugin marketplace add perplexityai/modelcontextprotocol
# Then run: /plugin install perplexity
```
### Cursor, Claude Desktop & Windsurf
We recommend using the one-click install badge at the top of this README for Cursor.
For manual setup, all these clients use the same `mcpServers` format:
| Client | Config File |
|--------|-------------|
| Cursor | `~/.cursor/mcp.json` |
| Claude Desktop | `claude_desktop_config.json` |
| Windsurf | `~/.codeium/windsurf/mcp_config.json` |
```json
{
"mcpServers": {
"perplexity": {
"command": "npx",
"args": ["-y", "@perplexity-ai/mcp-server"],
"env": {
"PERPLEXITY_API_KEY": "your_key_here"
}
}
}
}
```
### VS Code
We recommend using the one-click install badge at the top of this README for VS Code, or for manual setup, add to `.vscode/mcp.json`:
```json
{
"servers": {
"perplexity": {
"type": "stdio",
"command": "npx",
"args": ["-y", "@perplexity-ai/mcp-server"],
"env": {
"PERPLEXITY_API_KEY": "your_key_here"
}
}
}
}
```
### Codex
```bash
codex mcp add perplexity --env PERPLEXITY_API_KEY="your_key_here" -- npx -y @perplexity-ai/mcp-server
```
### Other MCP Clients
Most clients can be manually configured to use the `mcpServers` wrapper in their configuration file (like Cursor). If your client doesn't work, check its documentation for the correct wrapper format.
### 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:
```bash
export PERPLEXITY_PROXY=https://your-proxy-host:8080
```
If your proxy needs a username and password, use:
```bash
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, you can run the server in HTTP mode:
#### Environment Variables
The HTTP server supports these configuration options:
- **`PORT`** - HTTP server port (default: `8080`)
- **`BIND_ADDRESS`** - Network interface to bind to (default: `127.0.0.1` for local, use `0.0.0.0` for hosted)
- **`ALLOWED_ORIGINS`** - Comma-separated list of allowed CORS origins (default: `http://localhost:3000,http://127.0.0.1:3000`, use `*` for public service)
- **`PERPLEXITY_API_KEY`** - Your Perplexity API key (required)
#### Using Docker
```bash
docker build -t perplexity-mcp-server .
docker run -p 8080:8080 -e PERPLEXITY_API_KEY=your_key_here perplexity-mcp-server
```
The server will be accessible at `http://localhost:8080/mcp`
#### Using Node.js Directly
```bash
npm install
npm run build
npm run start:http
```
Connect your MCP client to: `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.
