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.

What credentials does it need?

It reads `PERPLEXITY_API_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
