Reviewer notes

Source Reviewed review. These are observations, not a security certification.

Official Anthropic plugin. Connectors: Canva, Figma, HubSpot, Amplitude, Notion, Ahrefs, SimilarWeb, Klaviyo. Pairs well with cowork-context-file-architecture (brand-voice.md). Broad applicability across most businesses.

Anthropic-official knowledge-work-plugins repo. 10.8K stars. Connectors are account-scoped, not workspace-scoped (JJ Englert finding). This means connectors added in one workspace are accessible across all workspaces under the same Anthropic account.

2026-03-29: Connectors: Slack, Canva, Figma, HubSpot, Amplitude, Notion, Ahrefs, SimilarWeb, Klaviyo. Official repo: https://github.com/anthropics/knowledge-work-plugins/tree/main/marketing

2026-03-29: SECURITY FINDING (JJ Englert, Mar 2026): Cowork connectors are scoped at the Anthropic account level, NOT the workspace level. A connector added in one Cowork workspace is accessible in ALL workspaces under the same Anthropic account. This means: (1) connectors with sensitive access (email, calendar, CRM) bleed across all projects/workspaces; (2) multi-tenant setups sharing an Anthropic account are NOT isolated at the connector level; (3) evaluate connector blast radius across the full account, not just the workspace being configured.
