mcp-server-ms-365¶

An MCP server for Microsoft 365 through the Graph API: mail, calendar and to-do tasks (upstream: Softeria/ms-365-mcp-server). The binary keeps its upstream name. Companion package: mcprack-mcp-server-ms-365. Binary: /usr/bin/ms-365-mcp-server.

sudo apt install mcprack-mcp-server-ms-365

Configuration¶

Variable	Required	Meaning
`MS365_MCP_CLIENT_ID`	no	Client ID of your own Azure app registration; without it the default upstream app is used
`MS365_MCP_TENANT_ID`	no	Tenant ID for your own app registration
`MS365_MCP_CLIENT_SECRET`	no	Client secret of your own app registration (secret store)
`MS365_MCP_CLOUD_TYPE`	no	Microsoft cloud environment
`READ_ONLY`	no	Read-only is the default; `READ_ONLY=false` (or `--no-read-only`) enables write tools

Registration:

sudo mcprack server show mcp-server-ms-365
sudo mcprack server edit mcp-server-ms-365 --add-secret-key <SECRET_VARIABLE>
sudo mcprack secret set mcp-server-ms-365 <SECRET_VARIABLE>

Replace <SECRET_VARIABLE> with each secret variable from the table.

Read-only behaviour: Read-only is the upstream default. Many more MS365_MCP_* variables exist; see the upstream README.

Tools¶

Mail, calendar and to-do task tools over Microsoft Graph; write tools stay hidden until read-only mode is turned off.
