How do I connect the ClickHouse MCP Server to my AI client?

To connect ClickHouse to your client (like Claude Desktop or Cursor), add the server command to your configuration file (e.g., 'claude_desktop_config.json'). You can run it locally using npx or deploy it to our secure managed cloud at MCPserver.in with one-click.

What security controls are available on the ClickHouse integration?

The ClickHouse MCP server keeps your API credentials secured in environment variables on your host or deployed cluster. It executes tools in a sandboxed runtime, requiring user confirmation for write, delete, or external publishing actions.

Does the ClickHouse MCP Server support real-time data lookups?

Yes! By utilizing Model Context Protocol Resources, the ClickHouse server queries active API endpoints on-demand, returning live context directly to the LLM context window without relying on outdated web caches.

What are the typical use cases for the ClickHouse AI connector?

Common use cases include automating ClickHouse data lookups, pulling active report profiles, updating statuses directly from chat inputs, and synchronizing project files with development environments.

What is the cost of running the ClickHouse MCP integration?

Running the server locally on your machine is 100% free. If you deploy it to our fully-managed hosting in India for team access, it is covered under the Developer tier (₹999/mo) or our Pro plan with low-latency edge scaling.
