Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

Name	Description
`MS365_CLIENT_ID` Required	Azure AD application (client) ID. Every mode except client-token needs it.
`MS365_TENANT_ID` Optional	Azure AD tenant ID, or 'common'/'organizations'/'consumers'. Read by certificate, client-secret and oauth-proxy modes.
`MS365_CLIENT_SECRET` Optional, secret	Azure AD client secret (client-secret mode).
`MS365_CERT_PATH` Optional	Path to the certificate used by certificate mode.
`MS365_CERT_PASSWORD` Optional, secret	Password for the certificate at MS365_CERT_PATH, if it has one.
`MS365_ACCESS_TOKEN` Optional, secret	A Graph access token supplied directly (client-token mode).
`MS365_AUTH_MODE` Optional	Auth mode: interactive (default), certificate, client-secret, client-token or oauth-proxy.
`MS365_OAUTH_BASE_URL` Optional	Base URL of the OAuth proxy (oauth-proxy mode).
`MS365_READ_ONLY` Optional	Set to 'true' to expose read-only tools and refuse every write.
`MS365_ENABLED_TOOLS` Optional	Case-insensitive regular expression matched against tool names; only matching tools are registered. Not a comma-separated list.
`MS365_PRESETS` Optional	Comma-separated tool presets to enable instead of naming tools individually.
`MS365_ORG_MODE` Optional	Set to 'true' for organisation-wide (application-permission) behaviour.
`TRANSPORT_TYPE` Optional	Transport: 'stdio' (the default, and what this npm package is listed as) or 'httpStream' for remote/Docker deployments.
