Quick answer

What it does

Authenticates against Microsoft Graph with MSAL, then exposes Microsoft 365 operations as MCP tools: read and send Outlook mail, read and create calendar events, list and post Teams messages, browse OneDrive, and read or update Excel workbooks.

Best for

  • Outlook inbox triage from an agent
  • Free-busy lookup across Microsoft 365 calendars
  • Reading Teams threads for context
  • OneDrive and Excel file access

Not for

  • Google Workspace stacks
  • Unattended send without a human-in-the-loop step

Setup recipe

Pick your client, then follow the three steps.

  1. 1

    Install

    claude_desktop_config.json
    {
  "mcpServers": {
    "microsoft-365": {
      "command": "npx",
      "args": [
        "-y",
        "@softeria/ms-365-mcp-server"
      ]
    }
  }
}

    Paste under mcpServers. Fully quit and reopen Claude after editing.

    CLI or .mcp.json
    claude mcp add microsoft-365 -- npx -y @softeria/ms-365-mcp-server

    Run from your repo. Commit .mcp.json to share with your team.

    .cursor/mcp.json
    {
  "mcpServers": {
    "microsoft-365": {
      "command": "npx",
      "args": [
        "-y",
        "@softeria/ms-365-mcp-server"
      ]
    }
  }
}

    Global path: ~/.cursor/mcp.json. Reload window after editing.

    .vscode/mcp.json
    {
  "servers": {
    "microsoft-365": {
      "command": "npx",
      "args": [
        "-y",
        "@softeria/ms-365-mcp-server"
      ]
    }
  }
}

    VS Code uses the "servers" key (not "mcpServers").

    ~/.codeium/windsurf/mcp_config.json
    {
  "mcpServers": {
    "microsoft-365": {
      "command": "npx",
      "args": [
        "-y",
        "@softeria/ms-365-mcp-server"
      ]
    }
  }
}

    Open via Cascade → hammer icon → Configure.

    cline_mcp_settings.json
    {
  "mcpServers": {
    "microsoft-365": {
      "command": "npx",
      "args": [
        "-y",
        "@softeria/ms-365-mcp-server"
      ]
    }
  }
}

    Open via the Cline sidebar → MCP Servers → Edit.

    ~/.continue/config.json
    {
  "experimental": {
    "modelContextProtocolServers": [
      {
        "transport": {
          "type": "stdio",
          "command": "npx",
          "args": [
            "-y",
            "@softeria/ms-365-mcp-server"
          ]
        }
      }
    ]
  }
}

    Continue uses modelContextProtocolServers with a transport block.

    ~/.codex/config.toml
    # ~/.codex/config.toml
[mcp_servers.microsoft-365]
command = "npx"
args = [
  "-y",
  "@softeria/ms-365-mcp-server",
]

    Codex uses TOML. Each server is a [mcp_servers.<name>] subtable.

    ~/.config/zed/settings.json
    {
  "context_servers": {
    "microsoft-365": {
      "command": {
        "path": "npx",
        "args": [
          "-y",
          "@softeria/ms-365-mcp-server"
        ]
      }
    }
  }
}

    Zed calls them "context_servers". Settings live-reload on save.

    ChatGPT → Apps directory

    Microsoft 365 doesn't ship a hosted HTTPS endpoint today. ChatGPT supports remote MCP servers only — to use this server in ChatGPT you'll need to deploy it to a public HTTPS URL first (e.g. via Cloudflare Workers or Vercel) or wait for an official remote build.

  2. 2

    Set required secrets

    No credentials required — this MCP runs over stdio without authentication.

  3. 3

    Try a minimum working prompt

    Minimum working prompt pending verification. Try any prompt from the MCP’s README once installed.

Security & scope

Access scope
Read + write
Sandbox
OAuth 2.1 against Microsoft Graph with dynamically computed scopes: the server requests only the permissions implied by the tools that are enabled. --read-only strips write tools, --enabled-tools narrows the surface by regex, and --allowed-scopes adds a hard scope boundary that hides any tool whose Graph permissions are not allowlisted — an empty allowlist fails startup rather than silently widening.
Gotchas
  • The default personal-mode surface includes send-mail and calendar writes; retrieval-only deployments should run --read-only.
  • Org mode requests broad SharePoint scopes (Sites.Read.All and up) unless you configure Sites.Selected, which limits access to explicitly granted site collections.

Agent prompt pack

— copy into Claude, Cursor, or ChatGPT.
Paste into Claude, Cursor, or ChatGPT. Edit the [brackets] before sending.
Recommend the best MCP servers for [task: e.g. email work] in [client: Claude].

Constraints:
- Prefer tools that are [official | open-source | read-only] — pick what matters for my use case.
- Exclude MCPs that require [e.g. a paid plan, OAuth-only flows, remote-only transport].
- Return at most 3 picks, ranked.

For each pick include:
1. One-sentence rationale.
2. The ready-to-paste install snippet for my client.
3. Any required secrets I need to create before installing.

Cross-check the top-mcps.com listing: https://top-mcps.com/top-mcps-for-email
Compare Microsoft 365 against a real alternative. Swap the second MCP in [brackets] if you want a different match.
Compare Microsoft 365 MCP vs [Gmail MCP] for the following job: [describe the job, e.g. "let an agent create GitHub issues on bug triage"].

Judge them on:
- Setup time and complexity (what a new user hits first).
- Auth model (none / API key / OAuth 2.1) and credential risk.
- Transport (stdio / Streamable HTTP / SSE) and where the server runs.
- Required secrets and the blast radius if they leak.
- Operational risk in an unattended agent loop.
- Which one is "good enough" for a weekend prototype vs. production.

End with one sentence: which should I pick for my scenario, which is: [my scenario].

Asks the agent to install and verify. Works inside Claude Code, Cursor Agent, Codex CLI.
Install the Microsoft 365 MCP server for my [client: Claude] at the default config path for that client.

Use the exact install snippet published at https://top-mcps.com/mcp/microsoft-365 (fetch https://top-mcps.com/mcp/microsoft-365.json for the canonical server.json if you can read URLs).

Before finishing:
1. Create the required secrets (no secrets) and put them in the appropriate env block — do not hard-code them.
2. Restart or reload the client so it picks up the new server.
3. Verify the server is connected (green / running state) and at least one tool is listed.
4. If anything fails, read the client's MCP logs and report the exact error — do not silently retry.

Confirm when done and list the tools the server now exposes.
