Reviewer notes

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

Official Anthropic plugin. Connectors: HubSpot, Close, Clay, ZoomInfo, Fireflies, Slack, Notion. Niche to sales teams but very high value for that audience. /sales:call-prep is the killer use case.

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.

2026-04-02: LIMITATION: No Salesforce connector out-of-the-box despite it being the dominant CRM. Fireflies integration requires a paid Fireflies account.

2026-03-29: Connectors: Slack, HubSpot, Close, Clay, ZoomInfo, Notion, Jira, Fireflies, Microsoft 365. Official repo: https://github.com/anthropics/knowledge-work-plugins/tree/main/sales Plugin docs: https://support.claude.com/en/articles/13837440-use-plugins-in-cowork

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.
