CLI for Microsoft 365 MCP Server

Content

CLI for Microsoft 365 MCP Server lets Claude and other MCP clients use natural language to work through CLI for Microsoft 365. It can search command docs, get command documentation, run m365 commands, and retrieve best-practice guidance for authentication, error handling, output handling, and configuration.

The server does not log in by itself. It uses the same authentication context as the globally installed CLI for Microsoft 365, so the permissions available to Claude match the authenticated CLI session.

Installation

Install and authenticate CLI for Microsoft 365 first:

npm i -g @pnp/cli-microsoft365
m365 setup
m365 login

Then configure the MCP server:

{
  "mcpServers": {
    "CLI-Microsoft365": {
      "command": "npx",
      "args": ["-y", "@pnp/cli-microsoft365-mcp-server@latest"]
    }
  }
}

The README recommends configuring CLI output, prompt behavior, and help mode so the MCP server receives useful command output and error details.

Use Cases

• Search for the correct CLI command before changing Microsoft 365 resources.
• Ask Claude to explain a command's options before running it.
• Create SharePoint lists, columns, and items after reviewing the proposed command chain.
• Create or manage Teams resources with a human-approved prompt.
• Inspect or change Power Automate flow state.
• Create Planner plans, buckets, and tasks.
• Draft repeatable Microsoft 365 administration scripts from best-practice guidance.
• Keep CLI prompt handling disabled for non-interactive MCP command execution.

Safety and Privacy

This is a tenant-management control surface. Treat it as access to the signed-in Microsoft 365 account, not as a documentation helper. Review the exact command and tenant target before allowing writes, and use least-privilege identities for the task.

Natural-language prompts can become chains of CLI commands. Require explicit approval for create, update, delete, disable, permission, membership, posting, messaging, flow, app, and tenant-configuration operations. Keep tokens, certificates, secrets, tenant URLs, and sensitive command output out of prompts, issues, logs, screenshots, and committed files.
