Three depths of research sit behind it: a quick lookup for simple facts, a reasoning mode for comparisons and multi-step questions, and a deep mode that returns a long write-up on a topic, with the angles you want covered listed up front. It judges which depth a question needs. You bring your own paid Perplexity key, and setup is a short block pasted into your assistant's settings. The code has been quiet since November 2025 but still works.

README

Perplexity MCP Server

An intelligent research assistant powered by Perplexity's specialized AI models. Features automatic query complexity detection to route requests to the most appropriate model for optimal results. Unlike the Official server, it has search capabilities FOR EVERY TASK, essentially

It also forces the agent using the MCP to be specific

Tools

1. Search (Sonar Pro)

Quick search for simple queries and basic information lookup. Best for straightforward questions that need concise, direct answers.

const result = await use_mcp_tool({
  server_name: "perplexity",
  tool_name: "search",
  arguments: {
    query: "What is the capital of France?",
    force_model: false // Optional: force using this model even if query seems complex
  }
});

2. Reason (Sonar Reasoning Pro)

Handles complex, multi-step tasks requiring detailed analysis. Perfect for explanations, comparisons, and problem-solving.

const result = await use_mcp_tool({
  server_name: "perplexity",
  tool_name: "reason",
  arguments: {
    query: "Compare and contrast REST and GraphQL APIs, explaining their pros and cons",
    force_model: false // Optional: force using this model even if query seems simple
  }
});

3. Deep Research (Sonar Deep Research)

perplexity-mcp FAQ

Is it still being updated?
There have been no code changes since November 2025. It still runs, but nobody appears to be actively developing it.
Do I need to pay for anything?
Yes. You supply your own Perplexity key and Perplexity bills for the searches, with the deep research mode being the most expensive.
Which apps does it work in?
Any assistant that reads a local settings file, including Cline, Cursor, and Claude Desktop. The block you paste is the same in each.
Can I use this to write a researched summary on a topic?
Yes. The deep mode returns a long write-up and lets you name the specific areas you want it to cover.
How hard is setup?
You paste a short block containing your key into your assistant's settings file. Node needs to be installed on the machine.
How is it different from Perplexity's own connector?
The author's stated aim is that it searches on every request rather than only when asked, and nudges the assistant to ask sharper questions.
