GrowthBook MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to GrowthBook and the rest of your systems. It gives your agent 394 GrowthBook actions (144 reads, 207 writes and 43 that wait for a confirmation) and holds the GrowthBook credential itself, so the agent never does. It paces GrowthBook's limits and records every call.

Set up

Connect GrowthBook 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 GrowthBook.

    Bearer token. 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.

    • api_keyGrowthBook Secret Key (secret_...), sent as a Bearer token
    • hostWhere your GrowthBook lives: your host
    account { op: "connections.requirements", service: "growthbook" }
# 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.

    do    { action: "growthbook.members.list_members" }# get all organization members · read · 1 upstream callcheck { action: "growthbook.metrics.post_metric", input: { … } }# free: inputs, permissions, cost and confirmations, nothing sent

Top actions

The GrowthBook API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 12 of GrowthBook's 12 action names are shared with at least one other connector, so an agent learns them once.

Try it

Prompts to paste into Claude.

Each one names the GrowthBook actions it will call, so you know what it reads and what it changes before you send it.

  1. Readread

    Give me a one-line status for every active GrowthBook project.

    callsgrowthbook.projects.list_projects

  2. Writewrite

    Create a single metric in GrowthBook. Show me exactly what you will send before you save it.

    callsgrowthbook.metrics.post_metric

Governance for GrowthBook

Destructive actions wait for a yes.

43 GrowthBook actions are destructive. The first 10:

  • Removes a single user from an organizationgrowthbook.members.delete_member
  • Deletes a metricgrowthbook.metrics.delete_metric
  • Deletes a single featuregrowthbook.features.delete_feature
  • Deletes a single projectgrowthbook.projects.delete_project
  • Deletes a single segmentgrowthbook.segments.delete_segment
  • Deletes a single attributegrowthbook.attributes.delete_attribute
  • Deletes a single environmentgrowthbook.environments.delete_environment
  • Deletes a single saved groupgrowthbook.saved_groups.delete_saved_group
  • Deletes a single SDK connectiongrowthbook.sdk_connections.delete_sdk_connection
  • Delete a variation screenshotgrowthbook.experiments.delete_variation_screenshot

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 GrowthBook MCP server, answered.

Is there a GrowthBook MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 394 GrowthBook actions across feature revisions, config revisions, ramp schedules and saved group revisions, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by GrowthBook.

What do I need to connect GrowthBook?

GrowthBook Secret Key (secret_...), sent as a Bearer token. Plus your host. The free call account { op: "connections.requirements", service: "growthbook" } lists exactly what to paste.

Can an AI agent delete or change things in GrowthBook?

Only if its key allows it, and only with an explicit confirmation. 43 GrowthBook actions are destructive, including removes a single user from an organization, deletes a metric and deletes a single feature. 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 GrowthBook API limit?

actionlake paces every call to the limits in the GrowthBook service file: 60 calls a minute per connection. Repeated reads are answered from cache (135 GrowthBook actions can be), which never reaches GrowthBook.

What does a GrowthBook action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (394 GrowthBook actions page). Cache hits, searches, dry runs and calls GrowthBook 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 GrowthBook API does it cover?

The GrowthBook REST API 5.1.0 (OpenAPI 3.1.0) at api.growthbook.io/api by default, or the base URL set when you connect. It is built from GrowthBook's documentation as read on 23 October 2026. 394 actions in 49 areas, each one in the signed service file (version 1.0.0).

Does actionlake keep my GrowthBook 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 GrowthBook 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.
