MCP Tool Schema

Single unified tool web-search:

Parameter	Type	Default	Description
query	string	required	Search query
mode	"web" | "ai"	"web"	DuckDuckGo results or AI answer
backend	"iask" | "monica"	"iask"	AI backend (mode=ai only)
numResults	integer	3	Results count (web mode, 1-20)

Agent Prompt

Add this to your agent's system prompt to enable web search:

When you need to search the web or find current information, use the DDG Search CLI:

  npx -y @oevortex/ddg_search@latest "<query>" -m ai

This runs an AI-powered web search via IAsk. For standard DuckDuckGo results (titles + URLs + snippets), use mode "web" instead:

  npx -y @oevortex/ddg_search@latest "<query>" -m web -n 5

For a different AI backend (Monica), add -b monica. Use this for any research, fact-checking, or current events task.

Proxy Support

Respects HTTP_PROXY, HTTPS_PROXY, and NO_PROXY environment variables automatically.

HTTPS_PROXY=http://proxy:8080 ddg "search query"

Install

npm install -g @oevortex/ddg_search

Or use npx without installing.
