  "summary": "ClickHouse's official MCP server: run SQL, list databases and tables on a ClickHouse cluster (read-only by default), with optional embedded chDB queries.",
  "description": "Tools: `run_query` (with typed query parameters), `list_databases`, `list_tables` (paginated, with column metadata) and, with the optional `chdb` extra, `run_chdb_select_query` on the embedded chDB engine. Queries run read-only by default (`CLICKHOUSE_ALLOW_WRITE_ACCESS=false`); writes need an explicit opt-in and destructive statements such as `DROP` need a second flag, though the README notes the real security boundary is the ClickHouse user's grants. Defaults to stdio; HTTP/SSE transports require authentication by default and expose a `/health` endpoint. Install from PyPI as `mcp-clickhouse` (e.g. via `uvx`).",
