FAQ from DuckDuckGo Web Search MCP Server
What tools are provided by the server?
Two tools: search_and_fetch (searches DuckDuckGo and optionally fetches content) and fetch (fetches content of a given URL). The search_and_fetch tool accepts query (string) and limit (integer, default 3, max 10). The fetch tool accepts url (string).
How do I configure the server for Claude Desktop?
Add the server to claude_desktop_config.json using either the git+https method or, if that does not work, a local directory path as shown in the README. The command is uvx with arguments pointing to the repository or local folder.
What is the maximum number of search results I can request?
The limit parameter in search_and_fetch has a maximum value of 10. The default is 3.
Does the server require any API keys?
The README does not mention any API keys. The Jina API used for content fetching may have its own terms, but the server itself does not require additional authentication.
What transport protocol does the server use?
The server is MCP‑compliant and is intended to be launched via the uvx command. The README does not specify the transport layer, but typical MCP servers use stdio or HTTP.
