Perplexity MCP Server

Perplexity MCP server

A Model Context Protocol (MCP) server that provides web search functionality using Perplexity AI's API. Works with the Anthropic Claude desktop client.

Example

Let's you use prompts like, "Search the web to find out what's new at Anthropic in the past week."

Components

Prompts

The server provides a single prompt:

• perplexity_search_web: Search the web using Perplexity AI
  • Required "query" argument for the search query
  • Optional "recency" argument to filter results by time period:
    • 'day': last 24 hours
    • 'week': last 7 days
    • 'month': last 30 days (default)
    • 'year': last 365 days
  • Uses Perplexity's API to perform web searches

Tools

The server implements one tool:

• perplexity_search_web: Search the web using Perplexity AI
  • Takes "query" as a required string argument
  • Optional "recency" parameter to filter results (day/week/month/year)
  • Returns search results from Perplexity's API
