Hex MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Hex and the rest of your systems. It gives your agent 60 Hex actions (28 reads, 27 writes and 5 that wait for a confirmation) and holds the Hex credential itself, so the agent never does. It paces Hex's limits and records every call.

Set up

Connect Hex 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.

  2. 02

    Connect Hex.

    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.

    • access_tokenHex API token
    • hostWhere your Hex lives: your host
    account { op: "connections.requirements", service: "hex" }
# 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.

Capabilities

What an AI agent can do in Hex.

60 actions in 16 areas. Every one carries its effect, so a key can allow the reads and hold the rest.

Top actions

The Hex API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 20 of Hex's 20 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 Hex actions it will call, so you know what it reads and what it changes before you send it.

  1. Readread

    Who has access in Hex? List every user and their role.

    callshex.users.list

  2. Writewrite

    Create a group in Hex. Show me exactly what you will send before you save it.

    callshex.groups.create

Governance for Hex

Destructive actions wait for a yes.

5 Hex actions are destructive. These are all of them:

  • Delete a grouphex.groups.delete
  • Cancel a runhex.project_runs.cancel
  • Delete a cellhex.cells.delete
  • Deactivate a userhex.users.deactivate
  • Delete a draft guidehex.guides.delete_draft

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.

dohex.groups.deleteconfirm_policy: human

Delete a group?

intent: the user asked me to delete a group

Illustrative. Scoped to Hex only, capped at 2,000 upstream calls, every write confirmed, and the destructive ones approved by a named person.

Cost

What Hex costs on actionlake.

Every Hex action is one upstream call, the only thing actionlake bills. Searching, check, cost, account and any call Hex refused with 401, 403, 429 or a 5xx are free. 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.

Questions

The Hex MCP server, answered.

Is there a Hex MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 60 Hex actions across cells, projects, data connections and groups, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Hex.

What do I need to connect Hex?

Hex API token. Plus your host. The free call account { op: "connections.requirements", service: "hex" } lists exactly what to paste.

Can an AI agent delete or change things in Hex?

Only if its key allows it, and only with an explicit confirmation. 5 Hex actions are destructive, including delete a group, cancel a run and delete a cell. 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 Hex API limit?

actionlake paces every call to the limits in the Hex service file: 60 calls a minute per connection. Repeated reads are answered from cache (25 Hex actions can be), which never reaches Hex.

What does a Hex action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (60 Hex actions page). Cache hits, searches, dry runs and calls Hex 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 Hex API does it cover?

The Hex API 1.0.0 (OpenAPI 3.0.3) at app.hex.tech by default, or the base URL set when you connect. It is built from Hex's documentation as read on 23 October 2026. 60 actions in 16 areas, each one in the signed service file (version 1.0.0).

Does actionlake keep my Hex 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 Hex 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.
