ClickHouse Cloud MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to ClickHouse Cloud and the rest of your systems. It gives your agent 169 ClickHouse Cloud actions (83 reads, 59 writes and 27 that wait for a confirmation) and holds the ClickHouse Cloud credential itself, so the agent never does. It paces ClickHouse Cloud's limits and records every call.

Set up

Connect ClickHouse Cloud in three steps.

  1. 01

    Add actionlake to Claude.

    Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us.

    https://connect.actionlake.com/mcp
  2. 02

    Connect ClickHouse Cloud.

    Username and secret. No consent screen: your agent can connect it for you, but the key then passes through your chat. To keep it out of the model's context, paste it in the console instead. actionlake stores what you paste write-only, sealed under your tenant's key.

    • key_idClickHouse Cloud API key ID
    • key_secretClickHouse Cloud API key secret, shown once when the key is created
    account { op: "connections.requirements", service: "clickhouse_cloud" }
# free: exactly what to paste, and what is found for you
  3. 03

    Make the first call. Check before a write.

    Ask in plain words; Claude picks the action. Before anything changes, check validates the call and prices it, for free.

Top actions

The ClickHouse Cloud API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 35 of ClickHouse Cloud's 35 action names are shared with at least one other connector, so an agent learns them once.

A destructive action runs only with confirm: true. Under the human policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after.

Questions

The ClickHouse Cloud MCP server, answered.

Is there a ClickHouse Cloud MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 169 ClickHouse Cloud actions across service clickpipes, service clickstack dashboards, byoc infrastructure and keys, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by ClickHouse Cloud.

What do I need to connect ClickHouse Cloud?

ClickHouse Cloud API key ID and ClickHouse Cloud API key secret, shown once when the key is created. The free call account { op: "connections.requirements", service: "clickhouse_cloud" } lists exactly what to paste.

Can an AI agent delete or change things in ClickHouse Cloud?

Only if its key allows it, and only with an explicit confirmation. 27 ClickHouse Cloud actions are destructive, including remove an organization member, delete a role and delete key. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it.

Will an AI agent use up my ClickHouse Cloud API limit?

actionlake paces every call to the limits in the ClickHouse Cloud service file: 10 calls per 10 seconds per connection. Repeated reads are answered from cache (75 ClickHouse Cloud actions can be), which never reaches ClickHouse Cloud.

What does a ClickHouse Cloud action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (169 ClickHouse Cloud actions page). Cache hits, searches, dry runs and calls ClickHouse Cloud refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Which ClickHouse Cloud API does it cover?

The ClickHouse Cloud API v1 (OpenAPI 3.1.1, 174 operations) at api.clickhouse.cloud. It is built from ClickHouse Cloud's documentation as read on 22 October 2026. 169 actions in 65 areas, each one in the signed service file (version 1.0.0).

Does actionlake keep my ClickHouse Cloud data, and where?

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 5 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your ClickHouse Cloud credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.

Which AI clients can use it?

Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
