  • execute_one_actionExecute One Actioncan change or delete data

    Execute a One action to perform actual operations on third-party platforms. CRITICAL: Only call this when the user's intent is to EXECUTE an action (e.g., 'read my last Gmail email', 'fetch 5 contacts from HubSpot', 'create a task in Asana'). DO NOT call this when the user wants to BUILD or CREATE code/forms/applications - in those cases, stop after find_one_actions and provide implementation guidance instead. REQUIRED WORKFLOW: Must call find_one_actions first, which returns the action's documentation. If uncertain about execution intent or parameters, ask for confirmation before proceeding.

  • find_one_actionsFind Platform Actionsread-only

    Use this to find the API actions a task needs, on any platforms, in one call: send one `requests` entry per operation (platform and a short intent) and get back, for each, the action to use with its documentation, plus a few alternatives. Large documents come back as a digest; call again with `load` for a section it omitted, the whole document, the table of contents, or an alternative's documentation. Results are limited to what this server's settings allow. Call list_one_integrations first to see the connected platforms.

  • list_one_integrationsList One Integrationsread-only

    List the platforms the user has connected on One. ALWAYS call this tool first in any workflow. Each connection has the kebab-case `platform` name (e.g., 'ship-station', 'shopify') and the `key` (the connectionKey for execute_one_action) you'll need for subsequent tool calls. Each connection carries an `access` field describing what you may run on it: `full`, a set of allowed HTTP `methods`, or a specific list of `actions` (each with `actionId`, `title`, `method`). When a connection is action-scoped, its `actions` are exactly what may run, so you need not search.
