Merge HRIS MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Merge HRIS and the rest of your systems. It gives your agent 71 Merge HRIS actions (52 reads, 13 writes and 6 that wait for a confirmation) and holds the Merge HRIS credential itself, so the agent never does. It paces Merge HRIS's limits and records every call.

Set up

Connect Merge HRIS 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 Merge HRIS.

    Header credentials. 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.

    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 Merge HRIS API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 21 of Merge HRIS's 21 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 Merge HRIS actions it will call, so you know what it reads and what it changes before you send it.

  1. Readread

    List everyone in Merge HRIS with their department and start date.

    callsmerge_hris.employees.list

  2. Writewrite

    Employees create in Merge HRIS. Show me exactly what you will send before you save it.

    callsmerge_hris.employees.create

Governance for Merge HRIS

Destructive actions wait for a yes.

6 Merge HRIS actions are destructive. These are all of them:

  • Passthrough createmerge_hris.passthrough.create
  • Field mappings deletemerge_hris.field_mappings.delete
  • Linked account deletemerge_hris.linked_account.delete
  • Remote keys regeneratemerge_hris.remote_keys.regenerate
  • Account token regeneratemerge_hris.account_token.regenerate
  • Async passthrough createmerge_hris.async_passthrough.create

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.

domerge_hris.field_mappings.deleteconfirm_policy: human

Cost

What Merge HRIS costs on actionlake.

Every Merge HRIS action is one upstream call, the only thing actionlake bills. Searching, check, cost, account and any call Merge HRIS 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 Merge HRIS MCP server, answered.

Is there a Merge HRIS MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 71 Merge HRIS actions across employees, field mappings, time off and timesheet entries, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Merge HRIS.

What do I need to connect Merge HRIS?

Merge production API key and X-Account-Token of the linked account this connection reads and writes. Plus your host. The free call account { op: "connections.requirements", service: "merge_hris" } lists exactly what to paste.

Can an AI agent delete or change things in Merge HRIS?

Only if its key allows it, and only with an explicit confirmation. 6 Merge HRIS actions are destructive, including passthrough create, field mappings delete and linked account delete. 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 Merge HRIS API limit?

actionlake paces every call to the limits in the Merge HRIS service file: 100 calls a minute per connection. Repeated reads are answered from cache (51 Merge HRIS actions can be), which never reaches Merge HRIS.

What does a Merge HRIS action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (20 Merge HRIS actions page). Cache hits, searches, dry runs and calls Merge HRIS 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 Merge HRIS API does it cover?

The Merge HRIS API v1 (OpenAPI 3.0.3, info.version 1.0) at api.merge.dev/api/hris/v1 by default, or the base URL set when you connect. It is built from Merge HRIS's documentation as read on 23 October 2026. 71 actions in 35 areas, each one in the signed service file (version 1.0.0).

Does actionlake keep my Merge HRIS 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 Merge HRIS 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.
