At a glance: Data warehousing has exceptional MCP coverage — every major platform has official support. ClickHouse leads the open-source community with 720 stars. BigQuery offers a fully managed remote server. Snowflake brings Cortex AI integration. This is one of the strongest enterprise MCP categories. Rating: 4.5/5.
ClickHouse — Official Server (720 stars)
| Detail | Info |
|---|---|
| ClickHouse/mcp-clickhouse | 720 stars, Python, 4 tools |
Most starred data warehouse MCP server. Dual engine: remote ClickHouse clusters + embedded chDB engine. Safety defaults: read-only by default, write requires --allow-write, destructive ops need --allow-destructive. Three transports (stdio, SSE, Streamable HTTP).
Limitation: Only 4 tools — no describe_table without writing SQL.
DuckDB / MotherDuck — Official Server (441 stars)
| Detail | Info |
|---|---|
| motherduckdb/mcp-server-motherduck | 441 stars, Python, MIT, 5 tools |
Universal data access: local DuckDB files, in-memory, S3, and MotherDuck cloud — all from the same server. switch_database_connection lets agents move between sources on the fly. DuckDB can query Parquet, CSV, JSON, and Iceberg files directly. The best option for cross-source analytical work.
Snowflake — Official Snowflake Labs (256 stars)
| Detail | Info |
|---|---|
| Snowflake-Labs/mcp | 256 stars, Python |
Goes well beyond SQL: Cortex Analyst for semantic data querying, Cortex Search for unstructured data RAG, Cortex Agent for agentic orchestration, SQL execution, object management, semantic views. Enterprise RBAC applies to all MCP operations.
Community: isaacwasserman/mcp-snowflake-server (180 stars) offers an insights memo that accumulates analytical patterns.
Google BigQuery — Managed Remote Server
Endpoint: bigquery.googleapis.com/mcp — zero local installation required. OAuth 2.0 + IAM. Auto-enabled after March 17, 2026. Full governance, ML forecasting, 1GB query processing limit for cost control. Preview status.
Community: ergut/mcp-bigquery-server (133 stars), LucasHild/mcp-server-bigquery (123 stars).
Databricks — Managed MCP with Unity Catalog
Governance-first: Genie (natural language data access), Vector Search (RAG), UC Functions (custom governed tools). On-behalf-of-user auth — audit logs correctly attribute every query. Beta status.
Community: JustTryAI/databricks-mcp-server (46 stars, 11 tools), RafaelCartenet/mcp-databricks-server (36 stars, lineage analysis).
Amazon Redshift — AWS MCP Suite
Part of awslabs/mcp (8,500+ stars). Auto-discovers provisioned clusters and serverless workgroups. Read-only for now. Works alongside S3, Lambda, and other AWS MCP servers.
What's Missing
No cross-warehouse query server — each platform needs its own server
No cost monitoring — no query cost estimation in any server
No data quality/profiling built into any server
No dbt integration in warehouse servers
Bottom Line
Rating: 4.5/5 — Universal vendor backing, safety-first defaults, managed remote servers, and deep AI integration from Snowflake's Cortex. Missing cross-warehouse federation and cost monitoring prevent a perfect score, but the fundamentals are exceptional. Production-ready across the board.
