Epic on FHIR MCP server for AI agents.
actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Epic on FHIR and the rest of your systems. It gives your agent 264 Epic on FHIR actions (229 reads and 35 writes) and holds the Epic on FHIR credential itself, so the agent never does. It paces Epic on FHIR's limits and records every call. Connecting Epic on FHIR needs your own Epic on FHIR OAuth app and one admin sign-in.
100,000 free calls a month. No card, no email, no password: press Start a free sandbox on the next screen and keep the key it shows you.

Set up
Connect Epic on FHIR in three steps.
- 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.

Connect Epic on FHIR.
OAuth 2.0, authorization code. You register your own OAuth app with Epic on FHIR, an admin signs in once, and you paste the app's client id and secret and the tokens from that sign-in; actionlake renews the access token from then on. actionlake stores what you paste write-only, sealed under your tenant's key.
Before the first sign-in, Epic on FHIR needs an OAuth app of your own, registered in its developer portal. actionlake has no Epic on FHIR app to lend you.

Every write can wait for a yes.
None of Epic on FHIR's actions is destructive. A key can still be held to reads, capped, and set so a person confirms every write.
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 Epic on FHIR MCP server, answered.
Is there an Epic on FHIR MCP server for Claude?
Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 264 Epic on FHIR actions across observations, patients, document references and allergy intolerances, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Epic on FHIR.
What do I need to connect Epic on FHIR?
Your own Epic on FHIR OAuth app, registered with Epic on FHIR (its client id and client secret), and the access and refresh tokens from one admin sign-in. actionlake has no Epic on FHIR app of its own, so this is not a one-step consent. actionlake renews the access token as it expires. Plus your host and your instance path. The free call account { op: "connections.requirements", service: "epic_fhir" } lists exactly what to paste.
Can an AI agent change things in Epic on FHIR?
Only if its key allows it. 35 Epic on FHIR actions write, and none is destructive. A key can be limited to reads, capped, and set so a person confirms every write.
Will an AI agent use up my Epic on FHIR API limit?
actionlake paces every call to the limits in the Epic on FHIR service file: 10 calls a second per connection. Repeated reads are answered from cache (4 Epic on FHIR actions can be), which never reaches Epic on FHIR.
What does an Epic on FHIR action cost?
One upstream call, the only unit actionlake bills. A list that pages bills one call per page (264 Epic on FHIR actions page). Cache hits, searches, dry runs and calls Epic on FHIR 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 Epic on FHIR API does it cover?
The Epic on FHIR (Epic EHR FHIR R4, STU3 and DSTU2 APIs) API Epic on FHIR, August 2026 release (FHIR R4 4.0.1, STU3 3.0.x, DSTU2 1.0.2) at your Epic on FHIR instance's API base URL, which you enter when connecting. It is built from Epic on FHIR's documentation as read on 23 October 2026. 264 actions in 70 areas, each one in the signed service file (version 1.0.0).
Can I combine Epic on FHIR with my other systems?
Yes. ask joins Epic on FHIR to ConnectWise PSA or NetSuite on the same customer and returns the answer rather than every row. Epic on FHIR maps crm.company, which 227 other connectors also map.
Does actionlake keep my Epic on FHIR data, and where?
actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to an hour, 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 Epic on FHIR 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.
