Cron jobs run on Loony infra. Every minute on free. Your data stays fresh without you thinking about it.

REST + MCP endpoints.

Query from your agent, your dashboard, or connect BI tools directly. Full OpenAPI spec included.

TerminalSchema

$ "Sync all Slack channels and messages nightly. Build a weekly digest showing the busiest channels, most active users, and average thread response time. Flag any channel that went silent for more than 7 days."

✓ Schema validated
✓ Database provisioned
✓ Scripts deployed
✓ Schedules registered

Done.

# Your data is now at:
REST  /data/v1/slack/query
MCP   /mcp/v1/slack/mcp
SQL   psql $DATABASE_URL

What you get

Slack's free plan deletes messages older than 90 days — conversations, decisions, and context vanish forever. Loony syncs your workspace on a schedule and stores every message in your own Postgres, so nothing is lost. Your agent can search two years of history, correlate discussion spikes with shipped features, and answer 'What did we decide about X last October?' without anyone remembering.
