send-emailSend an email to your recipient email address using Mailtrap Email API. You can send emails to multiple recipients at once.batch-send-transactional-emailSend a batch of transactional emails in one Mailtrap API call. Shared fields go on `base`; per-recipient overrides go in `requests[]`. Each request must include `to`.batch-send-bulk-emailSend a batch of bulk emails (Mailtrap bulk-stream API) in one call. Shared fields go on `base`; per-recipient overrides go in `requests[]`. Each request must include at least one of `to`/`cc`/`bcc`.create-templateCreate a new email templatelist-templatesList the account's email templates with page-token pagination (`token`, `per_page`). Pages are offsets over the newest-first list, so after deleting templates list again from token 1 instead of continuing with the next token.get-templateGet a single email template by ID, including subject, category, and HTML/text body.update-templateUpdate an existing email templatedelete-templateDelete an existing email templatesend-sandbox-emailSend an email in sandbox mode to a test inbox without delivering to your recipientsbatch-send-sandbox-emailSend a batch of emails in sandbox mode to a test inbox in one Mailtrap API call.

loginAuthenticate with Microsoft accountlogoutLog out from Microsoft accountverify-loginCheck current Microsoft authentication statuslist-accountsList all Microsoft accounts configured in this server. Use this to discover available account emails before making tool calls. Reflects accounts added mid-session via --login.select-accountSelect a Microsoft account as the default. Accepts email address (e.g. user@outlook.com) or account ID. Use list-accounts to discover available accounts.remove-accountRemove a Microsoft account from the cache. Accepts email address (e.g. user@outlook.com) or account ID. Use list-accounts to discover available accounts.graph-batchCombine up to 20 Graph requests into a single HTTP call. Body: { requests: [{ id: '1', method: 'GET'|'POST'|'PATCH'|'DELETE', url: '/me/messages?$top=5', headers?: {...}, body?: {...}, dependsOn?: ['1'] }, ...] }. Returns { responses: [{ id, status, body, headers }] } in arbitrary order — match by id. Use cases: (1) parallelize many small reads (e.g. fetch 15 mail messages by id in one round-trip); (2) sequence dependent writes via dependsOn; (3) batch many Excel range writes into one call to dramatically reduce latency on large workbook builds. Note: each sub-request URL is relative to the Graph version root (/me/..., /drives/..., NOT https://graph.microsoft.com/v1.0/...). 💡 TIP: Combine up to 20 Graph requests into a single HTTP call. Body: { requests: [{ id: '1', method: 'GET'|'POST'|'PATCH'|'DELETE', url: '/me/messages?$top=5', headers?: {...}, body?: {...}, dependsOn?: ['1'] }, ...] }. Returns { responses: [{ id, status, body, headers }] } in arbitrary order — match by id. Use cases: (1) parallelize many small reads (e.g. fetch 15 mail messages by id in one round-trip); (2) sequence dependent writes via dependsOn; (3) batch many Excel range writes into one call to dramatically reduce latency on large workbook builds. Note: each sub-request URL is relative to the Graph version root (/me/..., /drives/..., NOT https://graph.microsoft.com/v1.0/...).list-subscriptionsRetrieve the properties and relationships of webhook subscriptions, based on the app ID, the user, and the user's role with a tenant. The content of the response depends on the context in which the app is calling; for details, see the scenarios in the Permissions section. 💡 TIP: Lists webhook subscriptions owned by the current app/user. Returns id, resource, changeType, notificationUrl, expirationDateTime, clientState. Use $filter=resource eq '/me/messages' to find subscriptions for a specific resource. No dedicated 'Subscription.*' scope exists — the caller must already have a read permission for the subscribed resource (e.g. Mail.Read for /me/messages), which is supplied by the tool that reads that resource.create-subscriptionSubscribes a listener application to receive change notifications when the requested type of changes occur to the specified resource in Microsoft Graph. To identify the resources for which you can create subscriptions and the limitations on subscriptions, see Set up notifications for changes in resource data: Supported resources. Some resources support rich notifications, that is, notifications that include resource data. For more information about these resources, see Set up change notifications that include resource data: Supported resources. 💡 TIP: Creates a webhook subscription for change notifications. Required body: { changeType (comma-separated: 'created,updated,deleted'), notificationUrl (HTTPS, must validate with token echo), resource (e.g. '/me/mailFolders/inbox/messages', '/users/{id}/events', '/teams/{id}/channels/{id}/messages'), expirationDateTime (ISO 8601, max varies by resource type — 1 hour for calls, 24h for messages, 3 days for mail), clientState (opaque string returned in notifications, for validation) }. Optional: includeResourceData (true enables rich notifications, requires encryptionCertificate + encryptionCertificateId). No dedicated scope — caller must have a read permission for the target resource (e.g. Mail.Read, Calendars.Read, ChannelMessage.Read.All, Files.Read.All).get-subscriptionRetrieve the properties and relationships of a subscription. See the table in the Permissions section for the list of resources that support subscribing to change notifications. 💡 TIP: Gets a specific webhook subscription by id. Use list-subscriptions to find the id. Returns full subscription details including resource, changeType, notificationUrl, expirationDateTime, applicationId.update-subscriptionRenew a subscription by extending its expiry time. The table in the Permissions section lists the resources that support subscribing to change notifications. Subscriptions expire after a length of time that varies by resource type. In order to avoid missing change notifications, an app should renew its subscriptions well in advance of their expiry date. See subscription for maximum length of a subscription for each resource type. 💡 TIP: Renews a webhook subscription by extending its expiration. Body: { expirationDateTime (ISO 8601, new expiry) }. Call before the current expirationDateTime to avoid missing notifications. Max extension varies by resource type — check Microsoft Graph docs for subscription limits.delete-subscriptionDelete a subscription. For the list of resources that support subscribing to change notifications, see the table in the Permissions section. 💡 TIP: Deletes a webhook subscription. No further change notifications will be sent. Use this to clean up stale subscriptions or stop receiving notifications. Use list-subscriptions to find the id.- +7 more on the listing page
