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
