# Build Teams.ai Apps with Anthropic Claude

Use `@youdotcom-oss/teams-anthropic` to add Claude models (Opus, Sonnet, Haiku) to Microsoft Teams.ai applications. Optionally integrate You.com MCP server for web search and content extraction.

## Choose Your Path

**Path A: Basic Setup** (Recommended for getting started)
- Use Anthropic Claude models in Teams.ai
- Chat, streaming, function calling
- No additional dependencies

**Path B: With You.com MCP** (For web search capabilities)
- Everything in Path A
- Web search and content extraction via You.com
- Real-time information access

## Decision Point

**Ask: Do you need web search and content extraction in your Teams app?**

- **NO** → Use **Path A: Basic Setup** (simpler, faster)
- **YES** → Use **Path B: With You.com MCP**
