# The ClickHouse MCP server

> How the ClickHouse MCP server provides the open-standard access layer for the agentic data stack

The ClickHouse MCP server is the **open-standard access layer** of the [Agentic Data Stack](/products/agentic-data-stack/overview): it exposes ClickHouse to the chat front-end over the Model Context Protocol, so the agent can explore your data and run read-only queries against it.

In the stack, the open-source server runs alongside ClickHouse and is preconfigured in LibreChat. It exposes three tools to the agent:

* **List databases** — enumerate the databases in the connected ClickHouse instance.
* **List tables** — inspect the tables and their schemas within a database.
* **Run SELECT queries** — execute read-only queries and return the results.

To run it as part of the stack, see the [Docker setup guide](/products/agentic-data-stack/docker-setup). To use the ClickHouse MCP server with other clients and agent frameworks, or to read its source and configuration:

* [MCP integration catalog](/core/guides/use-cases/ai-ml/MCP): clients and agent-library guides.
* [MCP repository](https://github.com/ClickHouse/mcp-clickhouse): source and configuration.

<Info>
  **Prefer a managed MCP server?** ClickHouse Cloud offers a fully managed [Remote MCP server](/products/cloud/features/ai-ml/remote-mcp) — zero install, OAuth authentication, and a richer tool set that adds management operations (services, billing, ClickPipes, backups) on top of the read-only tools above. See its [comparison with the open-source server](/products/cloud/features/ai-ml/remote-mcp#remote-vs-oss).
