Tools & capabilities

Mailtrap tools 125

  • 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 template
  • list-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 template
  • delete-templateDelete an existing email template
  • send-sandbox-emailSend an email in sandbox mode to a test inbox without delivering to your recipients
  • batch-send-sandbox-emailSend a batch of emails in sandbox mode to a test inbox in one Mailtrap API call. Shared fields go on `base`; per-recipient overrides go in `requests[]`. Requires `sandbox_id` or the MAILTRAP_SANDBOX_ID env var.
  • get-sandbox-messagesGet list of messages from the sandbox test inbox
  • show-sandbox-email-messageShow sandbox email message details and content from the sandbox test inbox. Optionally include spam report (SpamAssassin score) and HTML analysis (client compatibility) for email testing workflows.

  • discord_list_guildsList every Discord server (guild) the bot is a member of (id, name, member count, icon). Takes no arguments. Read-only. Start here to discover the guild_id needed by most other tools.
  • discord_get_guild_infoGet details about one server: name, description, member/channel/role counts, boost tier, owner, and creation date. Read-only. Use discord_get_server_stats for a finer breakdown (humans vs bots, channel types).
  • discord_list_channelsList all channels in a server, grouped by their parent category and ordered by position. Returns a JSON object keyed by category name. Read-only. Use discord_find_channel_by_name to locate a specific channel.
  • discord_find_channel_by_nameFind channels whose name contains a substring (case-insensitive). Returns matching channels (id, name, type) as a JSON array. Read-only. Useful for resolving a channel_id when you only know the channel's name.
  • discord_read_messagesRead messages from a text channel or thread, oldest-to-newest. Page backwards by re-calling with before set to the id of the oldest message you received, which walks a channel past the 100-message per-call cap. Requires the View Channel and Read Message History permissions. Returns { messages: [...] } with id, author, content, timestamp, attachment count, pinned flag. Use discord_search_messages to filter by keyword, or discord_fetch_pinned_messages for pinned messages only.
  • discord_send_messageSend a plain-text message to a channel or thread. For rich content (title, color, fields, images) use discord_send_embed; to attach a reply reference to an existing message use discord_reply_message. Requires the bot to have the Send Messages permission. Returns the new message ID.
  • discord_reply_messageReply to a specific message, attaching a reply reference so clients show it as a threaded reply. Use discord_send_message for a standalone message with no reference. Requires the Send Messages permission. Returns the new reply's message ID.
  • discord_edit_messageEdit the text content of a message previously sent by this bot. Discord forbids editing other users' messages, so this fails for non-bot messages. Use discord_edit_embed for embed messages. Works in text channels and threads. Returns the edited message ID.
  • discord_add_reactionAdd a single emoji reaction to a message as the bot. Requires the Add Reactions and Read Message History permissions. Use discord_remove_reactions to undo. Idempotent: re-adding the bot's existing reaction has no effect.
  • discord_create_threadCreate a thread, either branching from an existing message (pass message_id) or as a standalone thread in a text channel (omit message_id). Standalone creation requires a parent text channel and fails if channel_id is itself a thread. Requires the Create Public Threads permission. Returns the new thread's ID.
  • discord_bulk_delete_messagesPermanently delete multiple recent messages in one call. IRREVERSIBLE. SAFE BY DEFAULT: dry_run is true unless explicitly set to false, so call it first to preview, then re-call with dry_run:false to actually delete. Discord only allows bulk-deleting messages younger than 14 days; older ones are skipped. Requires the Manage Messages permission. Returns the number deleted.
  • discord_send_embedSend a single rich embed (title, description, color, fields, author, footer, images, timestamp). Use discord_send_message for plain text, or discord_send_multiple_embeds to send several embeds at once. Requires the Send Messages and Embed Links permissions. Returns the new message ID.
