m365-shared — Auth, Config & Global Concepts

Prerequisites

Install the CLI:

npm install -g github:zrosenfield/m365-cli
# or from source:
git clone https://github.com/zrosenfield/m365-cli && cd m365-cli && npm install && npm run build && npm link

Verify: m365 --version

Authentication

m365 supports three auth methods, tried in this order on every command:

1. SP_CLI_ACCESS_TOKEN env var
2. Client credentials (service principal) — if clientSecret is configured
3. Stored delegated token — set by m365 auth login

Permission models — choose one

Delegated (device code) — recommended, least privilege

The app acts as your signed-in user account. It can only access sites your account can access. No admin consent required.

# .env (no SP_CLI_CLIENT_SECRET)
SP_CLI_TENANT_ID=...
SP_CLI_CLIENT_ID=...

m365 auth login    # one-time browser sign-in; token stored in OS keychain
m365 sites list    # works, scoped to your account's access

App registration prerequisite: Authentication → Advanced settings → Allow public client flows → Yes (required for device code).

Tokens expire (typically 1 hour access / 90-day refresh). Re-run m365 auth login if you get auth errors.

Sites.Selected — app-only, scoped to specific sites

Best for headless agents. The app has no access until a SharePoint admin explicitly grants it per-site. Requires a client secret; no interactive login.

# .env
SP_CLI_TENANT_ID=...
SP_CLI_CLIENT_ID=...
SP_CLI_CLIENT_SECRET=...

m365 sites list    # works only for sites the admin has granted

Admin grants access once per site via Graph API (see README App Registration section).

Sites.ReadWrite.All — app-only, full tenant access

Easiest to set up but broadest blast radius. Requires Global/SharePoint Admin consent. Avoid unless you genuinely need tenant-wide access.

Auth commands

m365 auth setup    [--tenant-id <id>] [--client-id <id>] [--tenant-url <url>]
m365 auth login    # Device code flow; requires tenantId + clientId configured
m365 auth logout   # Delete stored keychain token
m365 auth token    # Print current access token; --raw for bare string

---

Configuration

Config is stored at ~/.m365-cli/config.json (mode 0600).

m365 config set [--tenant <url>] [--site <siteId>] [--drive <driveId>] [--tenant-id <id>] [--client-id <id>]
m365 config get

Keys:

Key	Description
tenantId	Azure AD tenant GUID or domain
clientId	App registration client ID
clientSecret	Client secret (omit for device code)
tenantUrl	Default SharePoint URL (e.g. https://contoso.sharepoint.com)
defaultSiteId	Default site ID used when --site is omitted
defaultDriveId	Default drive ID used when --drive is omitted

---

Global Option Precedence

Most commands accept --site and --drive flags that override config defaults:

1. CLI flag (--site, --drive, --tenant)
2. Config file defaults (defaultSiteId, defaultDriveId, tenantUrl)

---

Output Format

All commands output JSON to stdout:

{ "data": <result> }

Errors go to stderr:

{ "error": { "code": "...", "message": "...", "status": 404 } }

Use --raw (on m365 auth token) or pipe through jq .data to extract values.

---

Discover Sites and Drives

Before using file or list commands, discover the IDs you need:

# List all sites in tenant
m365 sites list | jq '.data[] | {id, displayName, webUrl}'

# Get root site
m365 sites get | jq '.data.id'

# Get site by URL
m365 sites get --url https://contoso.sharepoint.com/sites/mysite

# List drives (document libraries) in a site
m365 drives list --site <site-id> | jq '.data[] | {id, name}'

# Save defaults to avoid repeating flags
m365 config set --site <site-id> --drive <drive-id>

---

Required App Registration Permissions

Delegated (device code) — no admin consent needed:

• Sites.ReadWrite.All (delegated) — covers lists and list items too
• Files.ReadWrite.All (delegated)
• Mail.ReadWrite (delegated)
• Mail.Send (delegated)
• Calendars.ReadWrite (delegated)
• Calendars.ReadWrite.Shared (delegated)
• offline_access (delegated)

Sites.Selected — app-only, scoped:

• Sites.Selected (application) — admin consents this, then grants per-site via Graph API

Sites.ReadWrite.All — app-only, full tenant:

• Sites.ReadWrite.All (application) — requires Global/SharePoint Admin consent
• Files.ReadWrite.All (application)
• Lists.ReadWrite.All (application)

---

Security Rules

• Never log or expose the access token in command output (use m365 auth token --raw | ... and pipe directly).
• Config file is written with mode 0600; never commit ~/.m365-cli/config.json.
• Client secrets should use m365 auth setup rather than being placed in environment variables in scripts that get committed.
