- Spot pricing anomalies or unusual trends in your business data
One reviewer rated it highest-tier (highest) and reported it identified a $14K/month pricing anomaly a client's own data team had missed. Strongest for ad-hoc SQL analysis and statistical work.
Data analysts and teams with Snowflake, Databricks, or BigQuery. Works with exported CSVs for teams without data warehouse connectors.

Reviewer notes
Source Reviewed review. These are observations, not a security certification.
Official Anthropic plugin. Connectors: Snowflake, Databricks, BigQuery, Definite, Hex, Amplitude, Jira. Works with plain CSV too — low barrier entry point. /data:explore is excellent for one-off analysis. Strong client-readiness because it democratises SQL.
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 connector for dbt, Redshift, or Looker out of the box — the three most common alternatives at enterprises. Data teams on those stacks need custom MCP connectors.
2026-03-29: Connectors: Snowflake, Databricks, BigQuery, Definite, Hex, Amplitude, Jira. Official repo: https://github.com/anthropics/knowledge-work-plugins/tree/main/data
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.
