Query ClickHouse analytics safely from MCP clients
Use ClickHouse's official MCP server when an assistant needs schema-aware, reviewable analytics access to ClickHouse through bounded tools instead of ad hoc database credentials.

ClickHouse mcp-clickhouse is the official MCP server for connecting AI assistants to ClickHouse databases. It gives an agent a narrow tool surface for analytics work: list databases, inspect tables, fetch table metadata, and run SQL queries against a ClickHouse cluster with read-only mode enabled by default unless write access is explicitly configured.
What this skill actually does
Use this skill when a user wants an MCP-capable assistant to answer analytics questions, inspect schemas, prepare read-only SQL, or summarize operational data from ClickHouse without handing the assistant a raw database shell. The operator should configure ClickHouse connection settings, expose only the intended cluster or database scope, keep write access disabled unless there is a deliberate approval path, and review generated SQL before using results in reports, incidents, dashboards, or tickets.
This is not a generic ClickHouse listing or a broad database framework entry. The scope boundary is the official MCP bridge and its documented tools: configure credentials, connect the MCP server to an agent client, use schema/list/query tools for analytics, and keep permissions bounded. If the task is database migration, application development, or manual BI exploration, use the relevant database tooling directly instead.
Inputs and prerequisites: Python environment or package runner, the mcp-clickhouse package, ClickHouse host and credentials, MCP client configuration, and explicit policy for read-only versus write-enabled queries.
Setup notes: Install mcp-clickhouse from the upstream package instructions, set the required ClickHouse environment variables, keep CLICKHOUSE_ALLOW_WRITE_ACCESS=false by default, and register the server with the MCP client that will run the analytics workflow.
Source and verification boundary: use https://github.com/ClickHouse/mcp-clickhouse as the canonical reference before running the workflow; keep MCP tool calls, generated SQL, credentials scope, and query outputs reviewable against that upstream source.
