概要

What is Perplexity MCP Server?

The Perplexity MCP Server is a Node.js implementation of Anthropic's Model Context Protocol (MCP) that enables Claude to interact with Perplexity's language models. It provides a secure bridge between Claude and Perplexity AI’s capabilities through tool use.

How to use Perplexity MCP Server?

Install dependencies with npm install, create a .env file with your PERPLEXITY_API_KEY, and build with npm run build. Add the server to Claude Desktop by updating claude_desktop_config.json with the command to run the compiled dist/index.js and the environment variable for the API key.

よくある質問

How do I configure the server for Claude Desktop?

Edit `claude_desktop_config.json` (located at `%APPDATA%/Claude/config/` on Windows, `~/Library/Application Support/Claude/config/` on macOS, or `~/.config/Claude/config/` on Linux) and add the server entry with the correct path to `dist/index.js` and your `PERPLEXITY_API_KEY`.

What dependencies does it require?

Node.js, the `@modelcontextprotocol/sdk` (^1.0.3), `dotenv` (^16.4.7), and `isomorphic-fetch` (^3.0.0). The server is built with TypeScript.

What transport does the server use?

It communicates via stdio transport, as standard for MCP servers.

How are API keys managed?

The Perplexity API key is read from the `PERPLEXITY_API_KEY` environment variable, either from the `.env` file or from the `env` field in the Claude Desktop configuration.

What should I do if I get authentication errors?

Verify your Perplexity API key is correct in `.env` or the Claude Desktop config, and check that the key has the required permissions.
