Perplexity Web Search MCP Server

Most search and retrieval work still happens through a UI a human drives. Perplexity Web Search MCP server moves it into the conversation instead. A perplexity MCP server.

The short version

A simple MCP (Model Context Protocol) server that provides web search functionality using the Perplexity API. This server allows Claude or other MCP-compatible AI assistants to search the web and get up-to-date information.

• Search the web with Perplexity's powerful search capabilities
• Get comprehensive search results with sources and citations
• Filter results by time period (day, week, month, year)
• Includes a ready-to-use prompt template for web searches
• Supports loading API key from environment variables or .env file

Getting it running

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

What it needs from you

Configuration is passed through the environment: PERPLEXITY_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Things to watch

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

How it compares

Plenty of search and retrieval servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. It is maintained by nachoal; worth a glance at recent repository activity before you build anything load-bearing on it.
