Web Search

This repository exposes web search as a built-in integration in the Excel add-in.

Mapping

• Agent Skill name: web-search
• Excel integration ID: web_search
• Tools: web_search, fetch_page

Providers

Provider	API key	Notes
Jina (default)	Optional (for higher limits)	Works out of the box — no signup needed
Serper.dev	Required	Google SERP API, free tier available
Tavily	Required	AI-native search, free monthly credits
Brave Search	Required	Direct Brave Search API

If a keyed provider fails (auth/rate-limit/server error), search automatically retries with Jina and surfaces a warning.

Usage notes

• Prefer workbook data first.
• Use web search only when external facts are required.
• Cite sources from tool results ([1], [2], ...).

Excel-specific setup

1. Open /tools (or /extensions → Connections tab).
2. Enable external tools.
3. Enable Web Search for session and/or workbook scope.
4. (Optional) Choose a different provider and set its API key — Jina works by default with no configuration.
