DataChat: Read-Only SQL Analyst for Slack
DataChat: Read-Only SQL Analyst for Slack ships as a ready-to-import n8n automation package: load the bundled workflow JSON, connect the credentials listed on this page, and activate it on self-hosted n8n or n8n Cloud.
Let your team ask the Postgres database questions in plain English from Slack — with a hard read-only gate, real schema grounding, and a full audit log.
- Answer plain-English data questions in Slack with a single slash command, no SQL knowledge required
- Ground every query in your live table and column list so the AI stops inventing tables that do not exist
- Block every write: a quote-aware gate rejects anything but one plain SELECT, plus stacked statements, system catalogs, and file functions
- Cap every result with a forced row limit and a server-side statement timeout so a careless question cannot hammer production
- Hide sensitive tables and whole schemas from the assistant with a blocked-table list you control
- Restrict access to your Slack workspace and, optionally, to a named list of users
- Log every question, generated SQL, row count and outcome to Google Sheets for a complete audit trail
Setup Service — optional live install and test. Choose your tier at checkout (not tied to this template's price).
Paste the license key from your receipt. It must match this template.
Workflow summary
One workflow handles everything end-to-end.
- 1A teammate asks a question in Slack with a slash command and gets an instant acknowledgement
- 2Checks the question came from your workspace and, optionally, from someone on your allow-list
- 3Reads your database's live table and column list so the answer is grounded in your real schema
- 4AI drafts a single SQL query against that schema, never against a guess
- 5A read-only gate rejects anything that is not one plain SELECT, blocks system tables and sensitive tables, and forces a row limit
- 6Runs the approved query through a locked-down, timeout-protected database function
- 7AI explains the result in plain English and posts the answer, a formatted table, and the SQL back to the channel
- 8Logs every question, query, row count and outcome to a Google Sheets audit trail
