Perplexity MCP Server

A Model Context Protocol (MCP) server for the Perplexity API written in Go. This server enables AI assistants like Claude (Code and Desktop) and Cursor to seamlessly access Perplexity's powerful search and reasoning capabilities directly from their interfaces.

Description

The Perplexity MCP Server acts as a bridge between AI assistants and the Perplexity API, allowing them to:

Search the web and retrieve up-to-date information using Perplexity's Sonar Pro model via the perplexity_ask tool
Perform complex reasoning tasks using Perplexity's Sonar Reasoning Pro model via the perplexity_reason tool

This integration lets AI assistants like Claude access real-time information and specialized reasoning capabilities without leaving their interface, creating a seamless experience for users.

Key Benefits

Access to real-time information: Get current data, news, and information from the web
Enhanced reasoning capabilities: Leverage specialized models for complex problem-solving tasks
Seamless integration: Works natively with Claude Code, Claude Desktop, and Cursor
Simple installation: Quick setup with Homebrew, Go, or pre-built binaries
Customizable: Configure which Perplexity models to use for different tasks

Installation

Using Homebrew (macOS and Linux)

brew tap alcova-ai/tap
brew install perplexity-mcp

From Source

Clone the repository and build manually:

git clone https://github.com/Alcova-AI/perplexity-mcp.git
cd perplexity-mcp
go build -o perplexity-mcp-server .

From Binary Releases (Other platforms)

Download pre-built binaries from the releases page.

Usage

This server supports only the stdio protocol for MCP communication.

Setup with Claude Code

Adding to Claude Code:

claude mcp add-json --scope user perplexity-mcp '{"type":"stdio","command":"perplexity-mcp","env":{"PERPLEXITY_API_KEY":"pplx-YOUR-API-KEY-HERE"}}'

That's it! You can now use Perplexity in Claude Code.

Setup with Claude Desktop

Adding to Claude Desktop:

Exit the Claude Desktop MCP config:

code ~/Library/Application\ Support/Claude/claude_desktop_config.json

Add the Perplexity MCP server:

  {
    "mcpServers": {
+        "perplexity-mcp": {
+            "command": "perplexity-mcp",
+            "args": [
+                "--model",
+                "sonar-pro",
+                "--reasoning-model",
+                "sonar-reasoning-pro"
+            ],
+            "env": {
+                "PERPLEXITY_API_KEY": "pplx-YOUR-API-KEY-HERE"
+            }
+        }
    }
  }

Command Line Options

--model, -m: Specify the Perplexity model to use for search (default: "sonar-pro")
- Can also be set with the PERPLEXITY_MODEL environment variable
--reasoning-model, -r: Specify the Perplexity model to use for reasoning (default: "sonar-reasoning-pro")
- Can also be set with the PERPLEXITY_REASONING_MODEL environment variable

Example:

perplexity-mcp --model sonar-pro --reasoning-model sonar-reasoning-pro

Direct Execution

If you want to run the server directly (not recommended for most users):

Set your Perplexity API key as an environment variable:
```
export PERPLEXITY_API_KEY=your-api-key-here
```
Run the server:
```
perplexity-mcp
```
