ClickHouse MCP

Unknown

ClickHouse is a columnar database built for real-time analytics, and ClickHouse Inc.'s official MCP server gives agents SQL access to a live cluster plus chDB — an embedded engine that queries files and URLs directly, no ETL required. Locally it runs unauthenticated over stdio; over HTTP/SSE it supports a bearer token or OAuth/OIDC.

Why this server

  • run_query runs SQL against a live ClickHouse cluster, driven by plain-language requests
  • run_chdb_select_query analyzes CSV/Parquet over a URL with no ETL and no database of your own
  • list_databases and list_tables map the cluster's structure before the first query
  • The local stdio mode needs no auth — HTTP/SSE is protected by a bearer token or OIDC

Usage examples

Prompt: How many events came in per source over the last 24 hours?

Result: The agent called list_tables to find the right events table, then run_query grouped by source and time — with no hand-written SQL.

Prompt: Analyze this CSV file from a link — any sales anomalies in March?

Result: run_chdb_select_query ran aggregations directly on the URL file via chDB, without loading the data into the ClickHouse cluster.
