Integrates with Perplexity AI API to enable web search capabilities for retrieving up-to-date information across domains.
  1. Sign up or Log in to Perplexity AI

    • Go to https://www.perplexity.ai and create an account if you don’t already have one. Otherwise, log in to your existing account.
  2. Navigate to the Perplexity AI API Settings

    • In your user dashboard, locate the section for “API” or “API Keys.” This is typically found under account settings or a similar option.
  3. Create a New API Key

    • Click the option to create or generate a new API key.
    • If prompted, assign a name to the key for identification.
    • Adjust any permissions or scopes as needed for your use case (if configurable).
  4. Copy Your API Key

    • After the key is generated, copy the entire string. You will need this for configuration.
    • Be careful: the API key is usually shown only once at creation for security reasons.
  5. Add the API Key in FastMCP

    • In the FastMCP connection interface, click the "Install Now" button for the Perplexity MCP server.
    • When prompted, fill in the required field for PERPLEXITY_API_KEY with your copied key value.
    • (Optional) You may also specify PERPLEXITY_MODEL if you wish to use a different model. If left blank, it will default to "sonar". Refer to the Perplexity AI model documentation for available models.
  6. Save and Complete Installation

    • Confirm your entries and save.
    • The MCP server is now ready for use in the FastMCP environment.
