Overview

What is Perplexity MCP Server?

An intelligent research assistant that integrates with Perplexity’s specialized AI models via the Model Context Protocol. It automatically detects query complexity and routes requests to the most appropriate model for optimal results, and forces the AI agent to be specific. Unlike the official server, it provides search capabilities for every task.

How to use Perplexity MCP Server?

Install Node.js, get a Perplexity API key from perplexity.ai/settings/api, then configure your MCP client with the server either by pointing to a local build (node /path/to/build/index.js) or directly via npx -y perplexity-mcp. Pass the API key through the environment variable PERPLEXITY_API_KEY, a command‑line --api-key argument, or a .env file using the --cwd argument. Use the three provided tools: search, reason, and deep_research.

FAQ from Perplexity MCP Server

What tools does Perplexity MCP Server provide?

search (Sonar Pro) for simple queries, reason (Sonar Reasoning Pro) for complex analysis, and deep_research (Sonar Deep Research) for thorough investigations. Each accepts an optional force_model parameter.

How is this different from the official Perplexity MCP server?

This server provides search capabilities for every task, whereas the official server does not. It also forces the agent to be specific.

What are the runtime and dependency requirements?

Node.js from nodejs.org and a valid Perplexity API key from perplexity.ai/settings/api.

How can I pass my Perplexity API key?

Three methods in order of priority: command‑line --api-key argument, PERPLEXITY_API_KEY environment variable, or a .env file located via the --cwd argument.
