Perplexity Researcher

🚀 MCP Researcher Server

A powerful research assistant integrated with Cline and Claude Desktop! Leverage Perplexity AI for intelligent search, document retrieval, API discovery, and code modernization assistance—right at your fingertips while coding.

✨ Features

• Smooth Context Tracking: Maintain conversation history in an SQLite database to ensure consistent responses across multiple queries.
• Advanced Query Processing: Employ Perplexity's Sonar model for complex reasoning and detailed answers to tackle various complex problems.
• Intelligent Rate Management: Implement adaptive rate limiting combined with an exponential retry strategy to maximize API usage efficiency without hitting limits.
• High-Performance Network Optimization: Optimize API calls through connection pooling and an automatic retry mechanism to ensure stable and reliable operation.

💻 Tools

1. Search

Perform general search queries to obtain comprehensive information on any topic. Examples show how to use different levels of detail (concise, regular, detailed) to get tailored responses.

2. Get Documentation

Retrieve documentation and usage examples for specific technologies, libraries, or APIs. Examples demonstrate how to obtain comprehensive documentation for React hooks, including best practices and common issues.

3. Find APIs

Discover and evaluate APIs that can be integrated into your project. Examples show how to find payment processing APIs and conduct a detailed analysis of features, pricing, and integration complexity.

4. Check Deprecated Code

Analyze code for deprecated features or patterns and provide migration guidance. Examples demonstrate how to check for modern alternatives to React class components and lifecycle methods.

📦 Installation Guide

Paste the following directly into Claude, and the AI will complete the installation for you:

1. First, install Node.js (download from nodejs.org if not already installed).
2. Clone the code repository.
3. Install dependencies and build the project.
4. Obtain a Perplexity API key from https://www.perplexity.ai/settings/api.
5. Create an MCP settings file according to your operating system.
6. If using with Claude Desktop, add server configuration.
7. If integrating with Cline, add to mcpServers:

{
  "mcpServers": {
    "perplexity-server": {
      "command": "node",
      "args": ["[path/to/researcher-mcp/build/index.js]"],
      "env": {
        "PERPLEXITY_API_KEY": "pplx-...",
        "PERPLEXITY_MODEL": "sonar-reasoning" // You can use different models
      },
      "disabled": false,
      "alwaysAllow": [],
      "autoApprove": [
        "search",
        "get_documentation",
        "find_apis",
        "check_deprecated_code",
        "get_request_status"
      ]
    }
  }
}

8. Build the server: npm run build
