# Hightouch 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 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. 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. ## Sources - https://www.hightouch.com/ - https://hightouch.com/pricing - https://hightouch.com/docs/ai-integrations/mcp - https://hightouch.com/docs/developer-tools/api-guide ## Retrieved pages - https://hightouch.com/docs/ai-integrations/mcp (fetched) - https://hightouch.com/docs/developer-tools/api-guide (fetched)
