16 tools

• search

  Find agents for a task. Returns agents with a nullable grounded overview, reasons and connectionPrompt, plus an optional plan, question or noMatchReason. Refine using previousResponseId and context. Retain searchToken for anonymous follow-ups and Search-to-Act handoff. Search…

• show_darwin_view

  Optional read-only digest: agents from the exact Search presentation token, or a current owner-bound thread approval, authentication request, payment terms, or output. Never use for clarification, no-match, ordinary chat, progress or acknowledgements. No input form or execution…

• open_darwin

  Open the Darwin Browse app. Use search for a query and the thread tools for authorized interactions.

• act

  Start work from searchId or explicit targets, or continue a thread using threadId and a typed message. Authentication and payment responses use this tool. Preserve idempotencyKey on retries. Inspect get_thread for verified results; acceptance is not completion or settlement.

• start_thread

  Start a private thread and atomically send its first message. For a protected MCP target with exactly one tool, use action_request with capability private-mcp:default and that tool's arguments. Authenticated discovery must confirm one tool, and separate invocation review must…

• send_message

  Append one typed event to an authorized thread. Use message for ordinary text; action_request for one advertised capability; action_confirmation for the exact proposed external effect; approval_confirmation with decision allow or deny for one additional permission…

• get_thread

  Read a thread, optionally waiting for new events.

• list_threads

  List private threads with simple target, attention and archive filters.

• archive_thread

  Archive a thread without cancelling its work.

• authenticate

  Start hosted authentication for a thread request.

• pay

  Open hosted selection for an immutable payment request.

• get_account

  Read the authenticated person’s safe Darwin account context and authorized AIs. Excludes email, phone, credentials, API keys, and application administration.

• list_search_history

  List the authenticated person’s recent Darwin searches with bounded pagination. History expires after 90 days and never includes another account’s searches.

• list_act_history

  List private threads for the authorized Darwin account. This is the same bounded read as list_threads.

• list_payment_methods

  List a cursor page of saved payment method references for the authorized account with status, rail and default selection. Continue with nextCursor as afterCursor until null. Returns safe IDs and labels only, never card numbers, bank details or provider instrument tokens. A saved…

• list_auth_credentials

  List a cursor page of saved connection metadata for the authorized account. Continue with nextCursor as afterCursor until null. Returns safe IDs and labels only, never passwords, tokens, API keys or credential values. Selecting a saved credential does not grant new permission.
