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).

Discourse MCP tools 16

  • discourse_select_siteValidate and select a Discourse site. Returns JSON with site URL and title.
  • discourse_searchSearch site content. Returns JSON object with results array of matching topics (id, slug, title) and meta (total, has_more).
  • discourse_filter_topicsDiscover topics through a filtered, top, or hot view. Filtered uses Discourse TopicsFilter syntax; top uses Discourse's authoritative top score and defaults to weekly; hot is defined exactly as daily top (not sentiment, controversy, or real-time velocity). Returns a uniform rich topic projection and truthful pagination metadata.
  • discourse_read_topicRead topic metadata and posts. Large post limits can require multiple upstream requests. For moderation queues, prefer reviewable list/detail evidence instead of fanning this tool out across flagged topics.
  • discourse_read_postRead a specific post. Returns JSON with id, topic_id, post_number, username, created_at, and raw content.
  • discourse_read_topic_postsRead exact, earliest, latest, around-post, or username-filtered topic evidence. Selection is bounded to 50 posts and reports the visible stream size without claiming the entire topic was loaded.
  • discourse_search_postsSearch post-level evidence with Discourse query syntax. Unlike discourse_search, this preserves matched posts, highlighted blurbs, authors, topics, categories, and truthful bounded continuation. This is keyword search, not Discourse AI semantic search.
  • discourse_get_userGet user info. Returns JSON with id, username, name, trust_level, created_at, bio, admin, and moderator.
  • discourse_list_user_postsGet paginated list of user posts/replies. Returns JSON object with posts array (id, topic_id, post_number, slug, title, created_at, excerpt, category_id) and meta (page, limit, has_more).
  • discourse_list_usersList users via admin API. Requires admin API key. Returns ~100 users per page (Discourse's fixed page size). Returns JSON with users array and pagination meta.
  • discourse_get_chat_messagesGet messages from a chat channel. Returns JSON object with channel_id, messages array (id, username, created_at, message, edited, thread_id, in_reply_to_id), and meta.
  • discourse_get_draftRetrieve a specific draft by key. Returns JSON with draft_key, sequence, and parsed data (title, reply, categoryId, tags, action).
