Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 13

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

stream
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_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_get_message
Fetch a single message by its id. GET /api/v2/chat/messages/{id}.
stream_get_reactions
List the reactions on a message. GET /api/v2/chat/messages/{id}/reactions.
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_unread_counts
Fetch total and per-channel unread message/mention counts for one user. GET /api/v2/chat/unread.
stream_query_channels
List/filter channels by a Stream query filter. e.g. filter {"type":"messaging"} or {"members":{"$in":["user-1"]}}. Returns channels with recent state. POST /api/v2/chat/channels.
stream_query_members
List/filter the members of one channel. Requires the channel type + id. Optional member filter, e.g. {"name":{"$autocomplete":"jo"}}. GET /api/v2/chat/members.
stream_query_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_query_users
List/filter users in the app. e.g. filter {"role":{"$eq":"admin"}} or {"id":{"$in":["u1"]}}. GET /api/v2/users.
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_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.
