<Update label="v2.2.0" description="5 Oct 2026">
  `new-events`

  Added webhook event support covering the thirty-eight event types Anthropic emits across sessions, vaults and vault credentials, agents, deployments and deployment runs, environments and memory stores. Every event shares one envelope, so each is routed on data.type, reports the resource it concerns as the record id from data.id, and carries the envelope's RFC3339 created\_at as the event date. Payloads carry identifiers rather than the resource itself. This connector exposes no actions for these resources, so a consumer that needs the full record fetches it from Anthropic's Managed Agents API by data.id. Webhook endpoints are created by hand in the Claude Console and point at the Native Webhook URL now shown on the linked account; a setup guide walks through that flow with screenshots and lists every event by the group the Console puts it in. The thirteen event types verified against live deliveries - across vaults, vault credentials, environments and memory stores - ship as preview; the twenty-five that could not be triggered on the available accounts ship as beta.

<Update label="v2.1.0" description="15 Sept 2026">
  `data-sync`

  Added DataSync support to all nine list actions — API keys, invites, models, organization users, workspaces, and the unified IAM users, groups, organizations and roles — so their records can be synced on a schedule and read back without calling Anthropic each time. Every action refreshes in full on each run, as the Anthropic Admin API exposes no updated-since filter on any list endpoint.

<Update label="v2.0.1" description="25 Aug 2026">
  `description-fix`

  Clarified list\_models description to reflect that it returns each model's ID, context window, and token limits but not per-model feature support (image input, PDF input, extended thinking), which is available via get\_model. Refreshed get\_model modelId example values to current models.

<Update label="v2.0.0" description="25 Aug 2026">
  `enhancement` `breaking-change`

  Breaking: scoped actions by auth type — admin API actions (users, workspaces, invites, api\_keys, org) now require admin\_api\_key, messages/models actions require standard API key. Removed old model enum values (claude-opus-4-0, claude-sonnet-4-0, claude-3-haiku-20240307), added latest models (claude-sonnet-5, claude-fable-5, claude-mythos-5, claude-opus-5, claude-opus-4-8, claude-opus-4-7). Improved pagination cursor descriptions for list\_models.
