What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

• stream_get_app

  Fetch the Stream app's settings and configured channel types. Good first call to confirm credentials and discover available channel types. GET /api/v2/app.

• stream_query_channels

  List/filter channels by a Stream query filter. e.g. filter {"type":"messaging"} or {"members":{"$in":["user-1"]}}. Returns channels with recent state. POST /api/v2/chat/channels.

• stream_get_channel

  Fetch a single channel's state (config, members) and its most recent messages. Note: uses Stream's get-or-create endpoint — for an existing channel it reads; if the type/id does not exist it may be created empty. POST /api/v2/chat/channels/{type}/{id}/query.

• stream_search_messages

  Search messages across channels. Scope with a channel filter (filter, e.g. {"type":"messaging"}) plus EITHER a full-text `query` OR a `message_filter` object (e.g. {"text":{"$q":"refund"}}). GET /api/v2/chat/search.

• stream_get_message

  Fetch a single message by its id. GET /api/v2/chat/messages/{id}.

• stream_get_replies

  Fetch the reply messages in a thread, given the parent message id. GET /api/v2/chat/messages/{parent_id}/replies.

• stream_get_reactions

  List the reactions on a message. GET /api/v2/chat/messages/{id}/reactions.

• stream_query_members

  List/filter the members of one channel. Requires the channel type + id. Optional member filter, e.g. {"name":{"$autocomplete":"jo"}}. GET /api/v2/chat/members.

• stream_query_users

  List/filter users in the app. e.g. filter {"role":{"$eq":"admin"}} or {"id":{"$in":["u1"]}}. GET /api/v2/users.

• stream_query_threads

  List threads (messages with replies). Server-side calls should pass a user_id to scope thread read-state to that user. POST /api/v2/chat/threads.

• stream_get_unread_counts

  Fetch total and per-channel unread message/mention counts for one user. GET /api/v2/chat/unread.

• stream_send_message

  ⚠️ WRITE: post a new message to a channel, attributed to user_id (must be an existing user in the app). POST /api/v2/chat/channels/{type}/{id}/message.
