Hightouch documentation

What it does

A CDP/reverse-ETL platform that syncs warehouse data (Snowflake, BigQuery, Databricks, Redshift) to 300+ downstream tools (ad platforms, CRMs, marketing automation) for audience activation and personalization.

Access and connection

MCP support: official

Access requirements: free - the REST API is open to all Hightouch users (bearer-token API key), available even on the free Basic Reverse ETL tier (up to 2 active syncs, unlimited destinations/seats, no sales conversation required for the API itself).

Authentication: Existing Hightouch workspace auth with role-based access control; however the MCP server itself "must be enabled by Hightouch - contact us to turn it on," so it is not self-serve activatable even though the auth mechanism itself is standard.
