Frequently asked questions
Yes. CorpusIQ connects PostgreSQL to ChatGPT, Claude, and Perplexity through the Model Context Protocol. The assistant translates natural-language questions into SQL, executes against a read-only role, and returns the result with the query shown.
Yes, and it is the recommended setup. Create a dedicated role with SELECT on the schemas you want to expose and nothing else. CorpusIQ enforces no writes on top of that, so even if the role had broader permissions, INSERT, UPDATE, DELETE, and DDL are blocked.
Yes. CorpusIQ accepts a standard PostgreSQL connection string, so any managed or self-hosted deployment works as long as the database is reachable and the connected role has SELECT on the relevant tables.
No. Query results are streamed through ephemerally and discarded after the answer is returned. Database contents are never copied, cached, or used to train models.
Yes. CorpusIQ connects 22+ tools at once. Ask ChatGPT to pull a query result from PostgreSQL and cross-reference it with Shopify orders or HubSpot CRM records in the same prompt.
