Add the ClickHouse MCP server to VS Code

Config last verified Jun 1, 2026

The exact config to run ClickHouse in VS Code — paste it in, restart, and the tools load.

Prerequisites

  • VS Code installed.
  • CLICKHOUSE_HOST — Hostname of your ClickHouse server.
  • CLICKHOUSE_USER — ClickHouse username used to authenticate.
  • CLICKHOUSE_PASSWORD — Password for the ClickHouse user.

Setup

1. Open .vscode/mcp.json

2. Add this configuration

Add to .vscode/mcp.json

.vscode/mcp.json
json
{
  "servers": {
    "clickhouse": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "--with",
        "mcp-clickhouse",
        "--python",
        "3.10",
        "mcp-clickhouse"
      ],
      "env": {
        "CLICKHOUSE_HOST": "<CLICKHOUSE_HOST>",
        "CLICKHOUSE_USER": "<CLICKHOUSE_USER>",
        "CLICKHOUSE_PASSWORD": "<CLICKHOUSE_PASSWORD>"
      }
    }
  }
}

Heads up

  • VS Code uses the `servers` key (not `mcpServers`) and requires `type`.

3. Restart VS Code and confirm the ClickHouse tools load.

Gotchas

  • VS Code uses the `servers` key (not `mcpServers`) and requires `type`.

VS Code is the exception to every other client: its top-level key is "servers", not "mcpServers", and each entry needs an explicit "type" (for example "http" or "stdio"). Secrets are not inlined; instead you declare an "inputs" array and reference each value as ${input:id}, so VS Code prompts for it once and never writes it to disk. Remote servers connect natively with OAuth.
