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

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: unconfirmed

Access requirements: Activations API plan requirements have not been verified here.

Authentication: Activations PATs are separate from Fivetran PATs. MCP authentication is not established for Activations.

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