carto-query-datawarehouse
Run SQL — spatial or otherwise — against any connection CARTO has registered. Two execution surfaces, matched across MCP and CLI:
Row-returning SELECT (1-min timeout) | DDL/DML & long queries (no timeout, no rows) | |
|---|---|---|
| MCP (primary) | execute_query | execute_async_query (submit/status/cancel) |
| CLI (fallback) | carto sql query | carto sql job |
Access-path routing. With the CARTO MCP server attached, run SQL throughexecute_queryandexecute_async_query— both available even on token-authenticated sessions. The dialect guidance and performance rules here apply identically on either path. Use thecarto sqlCLI when the server isn't attached or the SQL is scripted/CI.carto activity query(local DuckDB over downloaded activity data) is CLI-only — no MCP equivalent. Detection signals: `carto-basics/references/access-paths.md`.
When to use this skill
- The user wants to count rows, run an exploratory
SELECT, or build a transformation. - The user is debugging slow / failing SQL.
- The agent needs to materialize an intermediate table before authoring a map.
- The user wants an ad-hoc spatial join, buffer, or H3 aggregation.
Quick reference (CLI)
bash
# Read query (returns rows; 1-min timeout)
carto sql query <connection> "SELECT * FROM dataset.table LIMIT 10"
# Long-running job (DDL/DML; polls to completion; no rows back)
carto sql job <connection> "CREATE TABLE my_ds.out AS SELECT ..."
# From file / piped
carto sql query <connection> --file query.sql
echo "SELECT 1" | carto sql query <connection>| Use | Path |
|---|---|
Exploratory SELECT (small, fast) | sync — execute_query / sql query |
Cached SELECT (deterministic, 1y TTL) | sql query ... --cache |
CREATE TABLE AS SELECT, large UPDATE, 5+ min aggregation | async — execute_async_query / sql job |
--cache (CLI) switches to a GET with a 1-year cached response; use only for deterministic, small queries.

Always-on guidance
- Always specify a connection. The connection name comes from
explore_data(list_connections) /carto connections list, not the warehouse project ID. - Prefer the async path for any query that might exceed 60 s. Sync reads have a hard 1-minute server-side timeout regardless of the user's patience.
- Don't `SELECT
on warehouse tables blindly.** Spatial tables can be 100M+ rows; project columns and addLIMIT` for exploration. - Dialect mismatch is the #1 source of confusion.

carto activity query— CLI-only, DuckDB over downloaded data. See references/activity-queries.md.
