Frequently asked questions

What alternatives exist for file search in Microsoft 365?

This server provides direct MCP integration for AI assistants, bypassing manual searching and offering programmatic access via Microsoft Graph API.

What dependencies or runtime requirements are needed?

Python 3 and the `uv` package manager are required. An Azure-registered application with `Sites.Read.All` and `Files.Read.All` permissions is mandatory.

Where are cached files stored locally?

Cached files are stored in the `./src/mcp_m365_filesearch/.local/downloads` directory relative to the project root.

What are the known limits or performance considerations?

The server uses local caching to improve response times and reduce API calls, but no specific rate limits or file size caps are mentioned in the README.

How does authentication and transport work?

Authentication uses OAuth 2.0 client credentials (client ID, client secret, tenant ID) for Microsoft Graph. The server communicates over standard MCP transport via local stdio.
