Medplum MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Medplum and the rest of your systems. It gives your agent 591 Medplum actions (219 reads, 286 writes and 86 that wait for a confirmation) and holds the Medplum credential itself, so the agent never does. It paces Medplum's limits and records every call.

Set up

Connect Medplum 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 Medplum.

    OAuth 2.0, client credentials. Paste the app's client id and secret; actionlake fetches and renews the token, and nobody has to sign in. actionlake stores what you paste write-only, sealed under your tenant's key.

    • client_idMedplum ClientApplication ID (Medplum app > Project Admin > Clients > New client, or Admin > Clients; the client's…
    • client_secretThat ClientApplication's secret (shown on the client's page)
    • hostWhere your Medplum lives: your host
    account { op: "connections.requirements", service: "medplum" }
# 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: "medplum.users.list" }# search user resources · read · 1 upstream callcheck { action: "medplum.users.create", input: { … } }# free: inputs, permissions, cost and confirmations, nothing sent

Top actions

The Medplum API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 11 of Medplum's 11 action names are shared with at least one other connector, so an agent learns them once.

Prompts to paste into Claude.

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

  1. Readread

    List the companies in Medplum and flag likely duplicates by name or domain.

    callsmedplum.organizations.list

  2. Writewrite

    Create a User in Medplum. Show me exactly what you will send before you save it.

    callsmedplum.users.create

  3. Across systemsread

    Which Medplum companies have invoices in ConnectWise PSA, and how many each?

    callsmedplum.organizations.listconnectwise_manage.invoices.list

Across your systems

Medplum, joined to the rest of your business.

One ask fetches from Medplum and another system, joins the rows on the same customer on our side, and hands your agent the answer, not every row.

  • Which Medplum companies have invoices in ConnectWise PSA, and how many each?

    medplum.organizations.list + connectwise_manage.invoices.list, on crm.company · ConnectWise PSA

  • Which Medplum companies have tickets in HubSpot CRM, and how many each?

Governance for Medplum

Destructive actions wait for a yes.

86 Medplum actions are destructive. The first 10:

  • Delete a Usermedplum.users.delete
  • Delete an Appointmentmedplum.appointments.delete
  • Delete a Botmedplum.bots.delete
  • Delete a Flagmedplum.flags.delete
  • Delete a Goalmedplum.goals.delete
  • Delete a Listmedplum.lists.delete
  • Delete a Mediamedplum.media.delete
  • Delete a Slotmedplum.slots.delete
  • Delete a Taskmedplum.tasks.delete
  • Delete an Agentmedplum.agents.delete

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.

Cost

What Medplum costs on actionlake.

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

Is there a Medplum MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 591 Medplum actions across resources, agents, code systems and appointments, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Medplum.

What do I need to connect Medplum?

Medplum ClientApplication ID (Medplum app > Project Admin > Clients > New client, or Admin > Clients; the client's… and That ClientApplication's secret (shown on the client's page). Plus your host. The free call account { op: "connections.requirements", service: "medplum" } lists exactly what to paste.

Can an AI agent delete or change things in Medplum?

Only if its key allows it, and only with an explicit confirmation. 86 Medplum actions are destructive, including delete a User, delete an Appointment and delete a Bot. 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 Medplum API limit?

actionlake paces every call to the limits in the Medplum service file: 50 calls a second per connection. Repeated reads are answered from cache (210 Medplum actions can be), which never reaches Medplum.

What does a Medplum action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (591 Medplum actions page). Cache hits, searches, dry runs and calls Medplum 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 Medplum API does it cover?

The Medplum server API (FHIR R4 at /fhir/R4, plus /admin, /auth, /oauth2, /scim/v2, /email/v1, /cds-services) at api.medplum.com by default, or the base URL set when you connect. It is built from Medplum's documentation as read on 23 October 2026. 591 actions in 93 areas, each one in the signed service file (version 1.0.0).

Can I combine Medplum with my other systems?

Yes. ask joins Medplum to ConnectWise PSA or HubSpot CRM on the same customer and returns the answer rather than every row. Medplum maps crm.company, which 227 other connectors also map.

Does actionlake keep my Medplum 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 Medplum 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.
