Query Streams

Purpose: Query Streams provides governed access to databases and APIs for spreadsheets, AI clients, apps, and scheduled data syncs through an outbound-only Network Agent.
Nova AI: Nova accepts plain-English questions, reads the database schema, generates and runs read-only SQL, and returns metrics, tables, and charts.
AI integrations: Its hosted MCP server connects databases and API sources to Claude, Cursor, ChatGPT, and Grok using a revocable key.
Spreadsheet integrations: Excel and Google Sheets add-ins run shared saved queries and stream live results into spreadsheet cells without exposing the SQL to recipients.
Federated queries: Federated queries can join data across multiple databases and API sources in one SQL statement, with results returned as one table.
Connectors: The connector directory lists 53 sources, including 11 database engines, 27 hosted or managed services, 8 business APIs, and 7 file and folder types.
Automation: Scheduled SQL results can be sent to Smartsheet, Airtable, Google Sheets, SeaTable, Baserow, and Anvil as often as every five minutes.
Security: The Network Agent initiates an encrypted outbound connection, requires no inbound ports or VPN, and enforces SELECT, WITH, and EXPLAIN-only queries; database credentials stay on the user's network.
Usage limits: Usage is measured by megabytes of data processed rather than row count; the Free tier includes 5 MB per month and caps API and federated calls at 250 rows per call.
Trial: New accounts receive 30 days with every feature unlocked before moving to the Free plan, without a credit card.
Support: The site provides a contact form for questions and links to its documentation archive.
Price from: $15/mo
