# Census (now operates as "Fivetran Activations") documentation

Research date: 2026-08-24

Documentation coverage: partial.

Reference index, not a mirror of complete vendor documentation. Retrieved pages do not prove the MCP works.

## What it does

Was a standalone reverse-ETL tool for syncing warehouse data (Snowflake, BigQuery, etc.) into GTM tools like Salesforce/HubSpot without code; the product now lives inside Fivetran as "Activations," same function.

## Access and connection

MCP support: official

Access requirements: free - the Fivetran REST API, which now covers Activations, is available on all plans including the free trial.

Authentication: API key + secret via env vars (FIVETRAN_API_KEY, FIVETRAN_API_SECRET).

Research checked: 2026-08-24

These details come from catalog research. Check vendor sources for current setup instructions; this is not proof of a tested connection.
