Send a Dust message
Input
message requiredThe message to send.
conversationId requiredConversation sId to post into, e.g. "P35s1dnqSr".
agent optionalAgent sId to address, e.g. "dust". Defaults to "dust".

timeoutSeconds optionalHow long to wait for the reply (default 180).
Default: 180Output
url requiredagent requiredreply requiredThe agent's reply as markdown. Null when the agent produced no text (tool-only or errored turn) — a real outcome, not a parse failure.
completed requiredFalse means the wait expired while the agent was still working; the reply is partial.
sentMessageId requiredsId Dust gave the message that was sent.
waitedSeconds requiredconversationId requiredreplyMessageId requiredsId of the agent's reply.
Search Dust conversations
Search the signed-in Dust workspace's conversations by title text. Returns workspaceId and the matching conversations (sId, title, created, updated, spaceName), newest-updated first, with hasMore and nextCursor. sId is the join key for get_messages. The search covers conversation titles, not message bodies, so a word spoken inside a chat will not match unless it is also in the title — and Dust titles conversations automatically, so titles are paraphrases of the opening message. An empty match list is a real answer about the query, not a failure. Requires being signed in to dust.tt.
List Dust agents
List the agents available in the signed-in Dust workspace. Returns workspaceId and agents (sId, name, description, scope, status, model provider/id, userFavorite, canEdit, tags). sId is what you pass as `agent` to ask or send_message. Scope tells you where an agent comes from: "global" is a Dust built-in such as dust, helper, deep-dive or analyst, "workspace"/"published" is one your workspace created, "hidden"/"private" is personal. Requires being signed in to dust.tt.
Get Dust conversation messages
Read a Dust conversation's messages by conversation sId (from list_conversations or search_conversations), oldest first. Returns workspaceId, conversationId, title, a truncated flag, and messages: each with sId, role (user or agent), content, created, rank, plus author (the human's name/email on a user turn) and agent (the mentioned agent's id on an agent turn). The endpoint pages newest-first from the end of the conversation; this script walks that cursor backwards until it has the whole history or hits `limit`, then returns the messages in reading order. truncated is true when limit stopped it before the first message, so the oldest turns are missing. An unknown conversation id fails loudly rather than returning an empty transcript. Requires being signed in to dust.tt.
