One Search

1. Decide Which Search Providers You Want to Use

   • The server supports multiple providers: SearxNG, DuckDuckGo, Bing, Tavily, and Firecrawl.
   • For local-only search, no API keys are needed. For SearxNG, Tavily, Bing, or Firecrawl cloud, you will need API URLs and/or keys.

2. Obtain API URLs and Keys as Needed

   • SearxNG

     1. If using a public SearxNG instance, search for a list of public endpoints (example: searx.space). You may not need an API key unless using a private instance that requires authentication.
     2. If self-hosting SearxNG, deploy according to their documentation and use your server’s URL as SEARCH_API_URL.

   • Bing

     1. Go to the Microsoft Azure Portal.
     2. Create a new "Bing Search v7" resource.
     3. After deployment, go to your resource and find the "Keys and Endpoint" tab.
     4. Copy one of the listed keys (SEARCH_API_KEY) and the endpoint (SEARCH_API_URL).

   • Tavily

     1. Go to the Tavily Console.
     2. Sign up or log in.
     3. Navigate to your profile or API section to find your Tavily API key (SEARCH_API_KEY).

   • Firecrawl

     1. If using the Firecrawl cloud service, sign up at Firecrawl.
     2. Go to your dashboard and locate your API key (FIRECRAWL_API_KEY).
     3. Obtain the API URL (FIRECRAWL_API_URL), typically provided in their documentation or dashboard.
     4. If self-hosting, deploy Firecrawl using their instructions and use your server’s URL.

3. Fill in the ENV Values in the FastMCP Connection Interface

   • Click the “Install Now” button for OneSearch MCP Server.
   • In the FastMCP interface, fill in:
     • SEARCH_PROVIDER (e.g. searxng, tavily, bing, firecrawl, or local)
     • SEARCH_API_URL and SEARCH_API_KEY as obtained above (if required).
     • FIRECRAWL_API_URL and FIRECRAWL_API_KEY as obtained above (if you wish to enable Firecrawl cloud or your self-hosted service).
   • Leave variables blank if not using those providers.

4. Save and Proceed

   • After entering the required values for your chosen providers, save or confirm in the FastMCP interface.
   • You can now use web search and scraping through this server.

Note: For SearxNG and Firecrawl, if you want to deploy your own instance, refer to their deployment guides (SearxNG Deploy Guide, Firecrawl Deploy, as linked in their README).
