Tools & capabilities

AgentLair tools 15

  • claim_addressClaim a new @agentlair.dev email address for your agent. No DNS or SMTP setup required. Free tier: up to 3 addresses.
  • send_emailSend an email from an @agentlair.dev address you own to any recipient. No SMTP setup needed.
  • check_inboxCheck the inbox for an @agentlair.dev address. Returns recent messages with sender, subject, and received time.
  • read_messageRead the full content of a specific email message, including the body. Use message IDs from check_inbox.
  • list_addressesList all @agentlair.dev addresses claimed on your account.
  • vault_putStore a value in the AgentLair Vault. Use this to persist API keys, secrets, or any data your agent needs across sessions. Best practice: encrypt sensitive data client-side before storing (the server stores whatever you send).
  • vault_getRetrieve a stored value from the AgentLair Vault by key name.
  • vault_listList all keys stored in your AgentLair Vault (metadata only, values not returned).
  • vault_deleteDelete a key and all its versions from the AgentLair Vault.
  • calendar_create_eventCreate a calendar event on your AgentLair calendar. Events are published via iCal feed for human subscription (Google Calendar, Apple Calendar, Outlook).
  • calendar_list_eventsList events on your AgentLair calendar. Optionally filter by date range.
  • calendar_delete_eventDelete an event from your AgentLair calendar by event ID. Use calendar_list_events to find event IDs.

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).
