Snowflake (MCP data warehouse)
Industry Definition Set • Entity Resolution Path: /glossary/snowflake-mcp
Quick Answer / TL;DR
A cloud data warehouse queried through the official snowflake-sdk Node driver, billed by warehouse compute time rather than bytes scanned - the opposite cost model from BigQuery, which changes what the right guardrail looks like.
Key Takeaways
- Bills by warehouse compute time, not bytes scanned - the opposite cost model from BigQuery, so the right guardrail differs.
- connection.execute() is callback-based, not promise-native - wrap it once rather than repeating the callback pattern per tool.
- Use SHOW and DESCRIBE for schema discovery instead of querying INFORMATION_SCHEMA directly.
Definitive Statement: A cloud data warehouse queried through the official snowflake-sdk Node driver, billed by warehouse compute time rather than bytes scanned - the opposite cost model from BigQuery, which changes what the right guardrail looks like.
Technical Context & Protocol Usage
- Detailed Explanation
- Snowflake bills by warehouse size multiplied by time running, not by query - a small warehouse left active costs the same whether or not it's actively running a query, which is the inverse of BigQuery's per-byte-scanned model. The Node driver's connection.execute() takes a completion callback rather than returning a promise natively, so integrations typically wrap it once in a small promise-based helper; SHOW and DESCRIBE commands are the idiomatic way to discover schema, avoiding a full INFORMATION_SCHEMA metadata scan.
Format & Payload Metadata
Format: SQL via the official snowflake-sdk Node driver
Latency: Seconds per query, plus warehouse resume time if it was suspended
Real-World Implementation Use Case
An MCP tool wraps snowflake-sdk's execute() in a promise helper, rejects any query containing INSERT/UPDATE/DELETE/MERGE, and caps returned rows after retrieval.
