Security audit

Build Teams.ai Apps with Anthropic Claude

Security checks across malware telemetry and agentic risk

Overview

This skill is a coherent developer guide for adding Claude and optional You.com web tools to a Teams.ai app, with ordinary third-party API and data-sharing considerations.

Install only if your organization allows Teams messages and web-search inputs to be processed by Anthropic and You.com. Keep API keys out of source control, review and pin npm dependencies before production use, and disable or restrict the You.com MCP path for sensitive internal Teams workloads unless approved.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The MCP path encourages web search and content extraction but does not clearly disclose that user prompts and possibly fetched URLs/content may be transmitted to an external You.com service. In an enterprise Teams context, users may provide sensitive business data in prompts, so the lack of an explicit privacy/data-flow warning can lead to unintended third-party disclosure.
