Tools & capabilities

Imap MCP Server tools 40

  • imap_add_accountAdd a new IMAP account configuration
  • imap_update_accountUpdate an existing IMAP account. Useful for fixing SMTP settings without removing and re-adding the account.
  • imap_list_accountsList all configured IMAP accounts
  • imap_remove_accountRemove an IMAP account configuration
  • imap_connectConnect to an IMAP account
  • imap_disconnectDisconnect from an IMAP account
  • imap_test_accountTest an existing account connection without re-entering credentials. Validates IMAP connectivity and returns folder count and message count.
  • imap_search_emailsNote: on some servers a 'flagged' or starred message carries a custom keyword (e.g. an Open-Xchange color label or Apple's $MailFlagBit*) instead of, or in addition to, the \Flagged system flag. After any flagged search, inspect each result's customKeywords field before concluding a message is or isn't flagged — do not rely on the flagged filter alone. Search for emails matching criteria (sender, recipient, subject, body text, date range, read/flagged status). Use this to FIND messages when you know something about them but not their UID — e.g. "emails from amazon last week", "unread invoices". By default searches a single folder (INBOX). Set searchAllFolders=true to scan every mailbox at once — this catches messages filed away by rules (e.g. a receipt routed to a custom folder); Trash/Spam/Drafts are skipped unless you opt in. By default returns lightweight headers (uid, from, subject, date, and folder when searching across folders); set `includeBody=true` to also return the parsed body in one round-trip instead of paying the N+1 cost of calling imap_get_email per match. For the newest messages without criteria, prefer imap_get_latest_emails.
  • imap_get_emailRead the FULL content of a single email by its UID (body, sender/recipients, date, attachment list, optional raw headers and text-attachment previews). By default the body is returned as clean Markdown in markdownContent and raw HTML is omitted so it never crosses the boundary; set bodyFormat to "html" for the legacy raw htmlContent, or "text" for plain text only. Use after imap_search_emails or imap_get_latest_emails gives you a uid. Body text is truncated to maxContentLength to protect the context window — raise it for long messages. To fetch attachment bytes, use imap_download_attachment.
  • imap_upload_fileUpload a file to the server for use as an email attachment. Returns a path that can be used with imap_send_email attachments. This allows sending large attachments without hitting context window limits. Max size: 26214400 bytes (configurable via IMAP_MAX_UPLOAD_SIZE). Uploads are auto-deleted after 86400000 ms (configurable via IMAP_UPLOAD_TTL_MS).
  • imap_download_attachmentDownload a single attachment from an email (folder + uid + attachment filename/contentId, as listed by imap_get_email). Images are returned inline for viewing; PDFs are saved and their text is extracted inline (extractText); other files are saved to the shared downloads directory (or savePath). Use when the user wants the actual file contents, not just the message body.
  • imap_mark_as_readMark one or many emails as read. Accepts a single UID or an array — pass an array to flag N messages in one IMAP STORE round-trip (useful when triaging).

Ms 365 MCP Server tools 19

  • loginAuthenticate with Microsoft account
  • logoutLog out from Microsoft account
  • verify-loginCheck current Microsoft authentication status
  • list-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.
