email_list_accountsList all configured email accounts and their connection statusemail_add_accountAdd a new IMAP or iCloud email account (Gmail and Outlook require the setup wizard for OAuth)email_remove_accountRemove an email account: deletes its stored credentials, revokes the Google grant for Gmail accounts, and removes Outlook tokens from the local token cache. The result reports whether provider-side revocation succeeded.email_test_accountTest an email account connectionemail_list_foldersList all email folders for an accountemail_searchSearch emails with filters. By default returns compact results without full body content to save context. Set returnBody=true to include full email bodies.email_getGet a single email by IDemail_get_threadGet an email thread by thread IDemail_get_attachmentGet an email attachment by ID, returns base64 encoded dataemail_save_attachmentDownload an email attachment and save it directly to disk, returning metadata only (no base64 in the response) — avoids paying the token cost of round-tripping large attachments through the calling model. outputPath is relative to a fixed downloads directory (/home/user/.email-mcp/downloads, override with EMAIL_MCP_DOWNLOADS_DIR) and cannot escape it.email_sendSend a new emailemail_replyReply to an existing email- +21 more on the listing page

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'] }, ...] }.

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
