Sequel

Sequel is a platform that connects tools like GA4, Google Ads, HubSpot, Stripe, Search Console, BigQuery, Snowflake, and Postgres to AI assistants including Claude, ChatGPT, Cursor, and Codex via MCP. Connections are read-only by default, with access scoped per source. Users define metrics such as qualified lead, active account, or blended CAC once, and Sequel applies those definitions consistently. Sequel returns the query it ran with each result so numbers can be verified, and logs queries and actions. The site says connections use OAuth or a key and nothing needs self-hosting. Writes are disabled unless explicitly enabled and require the agent to show the exact call before running.
