Microsoft Graph CLI Cheatsheet

I've generally found the Microsoft Graph CLI (mgc) hard to work with. In many cases, harder than using the Graph API endpoints directly or language-specific SDKs. In general, Entra directory-related commands seem to work well, but other parts of the Graph API are rough around the edges from a usability perspective.

This doc provides some quick examples so I never have to work through the trial-and-error of figuring them out again.

Entra ID First Party Microsoft Applications

csv of pre-consented first-party applications listed via the servicePrincipals endpoint

The list (microsoft-first-party-applications.csv) can be generated via

mgc service-principals list --all --filter "appOwnerOrganizationId eq f8cdef31-a31e-4b4a-93e4-5f571e91255a" --count true --consistency-level eventual --select appId,displayName | jq -r '.value[] | [.appId, .displayName] | @csv'

This list is more extensive, but is missing entries compared to this page from Microsoft Documentation: Verify first-party Microsoft applications in sign-in reports. These applications are captured in applications-from-docs.csv.
