Side-by-side comparison

Microsoft 365 edges Google Workspace in score (89.33 vs 88.94) — a 0.39-point difference that reflects slightly better issue health (76% close rate vs Google Workspace's 72%). Google Workspace leads in community depth: 78 contributors and 1,840 stars vs Microsoft 365's 28 contributors and 538 stars. Both are community-maintained, not official vendor servers.

Data from March 19, 2026 crawl. Score = composite of stars 15%, freshness 25%, issue health 25%, contributors 10%, inbound dependents 25%.

Microsoft 365 MCP deep dive

Softeria/ms-365-mcp-server — score 89.33

Softeria/ms-365-mcp-server connects AI agents to Microsoft 365 and Office services via the Microsoft Graph API. The Graph API is Microsoft's unified endpoint for all M365 data — one authentication flow covers all of Outlook, Teams, SharePoint, OneDrive, and Office documents.

The server covers email (read, compose, send), calendar management, Teams messages and channels, SharePoint sites and lists, OneDrive files, and Office document operations. For enterprise Microsoft shops, this replaces multiple point integrations with a single MCP server backed by Microsoft's production Graph infrastructure.

538 stars and 28 contributors. Last commit March 11, 2026. Written in TypeScript, MIT licensed. The issue health signal is strong: 72 closed issues vs 23 open (a 76% close rate). The lower star count relative to Google Workspace reflects the timing of the project's launch, not quality.

Google Workspace MCP deep dive

taylorwilsdon/google_workspace_mcp — score 88.94

taylorwilsdon/google_workspace_mcp is one of the most comprehensively scoped MCP servers in the entire index. It covers nine Google Workspace services through their respective APIs: Gmail, Google Calendar, Docs, Sheets, Slides, Chat, Forms, Tasks, and Drive. The maintainer also includes a CLI tool for direct invocation outside the MCP protocol.

78 contributors makes this the highest-contributor MCP server outside the official SDKs and major frameworks. That depth suggests the codebase is actively reviewed and improved. 1,840 stars — the most starred productivity MCP server by a wide margin. Last commit March 17, 2026. Written in Python, MIT licensed.

The score of 88.94 (0.39 behind Microsoft 365) primarily reflects slightly lower issue health: 187 closed issues vs 71 open (72% close rate). Given the breadth of nine APIs, a larger open issue count is expected — and a 72% close rate is still healthy.

Feature coverage comparison

Verdict

This is the most straightforward decision in the MCP comparison series: pick the server that matches your productivity suite. There is no meaningful quality difference — both are well-maintained with healthy issue close rates and active contributor bases.

• Your organization uses Google Workspace (Gmail, Google Drive, Google Calendar): taylorwilsdon/google_workspace_mcp — score 88.94, 78 contributors, nine services covered.
• Your organization uses Microsoft 365 (Outlook, Teams, SharePoint, Office): Softeria/ms-365-mcp-server — score 89.33, Microsoft Graph API, full M365 coverage.
• Your organization uses both: Install both — they operate on different OAuth credentials and do not conflict. Many enterprise environments bridge Google and Microsoft products.

Neither server is official (vendor-maintained). Both are community projects with strong contributor depth. If official vendor support matters to your organization, monitor both projects for official adoption — Microsoft and Google both have MCP programs underway.

Setup guide

Install Google Workspace MCP

Requires Google OAuth credentials (client ID + secret from Google Cloud Console):

{
  "mcpServers": {
    "google-workspace": {
      "command": "uvx",
      "args": ["google-workspace-mcp"],
      "env": {
        "GOOGLE_CLIENT_ID": "your-client-id",
        "GOOGLE_CLIENT_SECRET": "your-client-secret"
      }
    }
  }
}

Install Microsoft 365 MCP

Requires Azure app registration with Microsoft Graph permissions:

{
  "mcpServers": {
    "ms365": {
      "command": "npx",
      "args": ["-y", "ms-365-mcp-server"],
      "env": {
        "TENANT_ID": "your-azure-tenant-id",
        "CLIENT_ID": "your-app-client-id",
        "CLIENT_SECRET": "your-app-client-secret"
      }
    }
  }
}

Both servers require OAuth app setup with their respective cloud providers. Google Workspace setup requires a Google Cloud project; Microsoft 365 setup requires an Azure app registration with appropriate Graph API permissions.
