DataAssist-IO

This is aremote MCP server— there is nothing to install or run yourself. You connect to it over an authenticated URL.

In Claude (Desktop or web), add a custom connector pointing at:

Claude will walk you through the OAuth sign-in. After you authorize, your org's tables appear as queryable tools.

DataAssist-IO is available as a published ChatGPT app — no manual setup required:

Point any client that supports the Streamable HTTP transport with OAuth at the endpoint above. The server implements OAuth discovery (/.well-known/oauth-protected-resource), so compliant clients negotiate authentication automatically.

Once connected, the assistant can use theseread-onlytools against the tables your admin has exposed to you:

Every tool isread-only by construction— queries are validated asSELECT-only and run against read-only database sessions. Nothing your assistant does can modify or delete your data.

- Files:CSV, Excel, SFTP-delivered CSV
- Databases:MySQL, PostgreSQL, MongoDB, AWS DocumentDB
- Warehouses:Google BigQuery, Amazon Redshift

File-based sources are imported and stored as Apache Iceberg tables on your behalf; live databases and warehouses are queried in place — your data is never copied.

- Per-organization isolation— every query is scoped to your org; tenants never see each other's data.
- OAuth-authenticated— no shared API keys; identity is established per user.
- Team-level table grants— admins control exactly which tables each team can reach.
- Full audit trail— every tool call is logged, with optional SOC2-grade request/response capture.
- Read-only enforcement— validated SELECT-only access plus read-only DB sessions, defense in depth.
