Bitwarden MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Bitwarden and the rest of your systems. It gives your agent 28 Bitwarden actions (12 reads, 12 writes and 4 that wait for a confirmation) and holds the Bitwarden credential itself, so the agent never does. It paces Bitwarden's limits and records every call.

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 Bitwarden 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 Bitwarden.

    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.

    account { op: "connections.requirements", service: "bitwarden" }
    # 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: "bitwarden.members.list" }# list members · read · 1 upstream callcheck { action: "bitwarden.members.create", input: { … } }# free: inputs, permissions, cost and confirmations, nothing sent

Top actions

The Bitwarden API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 26 of Bitwarden's 26 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 Bitwarden actions it will call, so you know what it reads and what it changes before you send it.

  1. Readread

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

    callsbitwarden.members.list

  2. Plandestructive

    Retire a group that no longer has members in Bitwarden. Ask me before anything is sent or changed.

    callsbitwarden.groups.getbitwarden.group_members.listbitwarden.collections.listbitwarden.group_members.replacebitwarden.groups.delete

  3. Planread

    Report who can reach a collection in Bitwarden.

  4. Writewrite

    Invite member in Bitwarden. Show me exactly what you will send before you save it.

The plan store

Ready-made plans for Bitwarden.

4 plans in the store. Install one and your agent runs it by name; the reply says which connections are still missing. A schedule can run a plan on a timetable. There are no triggers or webhooks, by design.

  1. Report who can reach a collection

    Use it when An auditor or a security review asks who currently has access to a particular Bitwarden collection.

Governance for Bitwarden

Destructive actions wait for a yes.

4 Bitwarden actions are destructive. These are all of them:

  • Remove memberbitwarden.members.delete
  • Delete groupbitwarden.groups.delete
  • Revoke memberbitwarden.members.revoke
  • Delete collectionbitwarden.collections.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.

dobitwarden.members.deleteconfirm_policy: human

Remove member?

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

Questions

The Bitwarden MCP server, answered.

Is there a Bitwarden MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 28 Bitwarden actions, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Bitwarden.

What do I need to connect Bitwarden?

Organization API key client_id (Admin Console > Settings > Organization info > API key; formatted… and Organization API key client_secret. Plus your api base and your tenant host. The free call account { op: "connections.requirements", service: "bitwarden" } lists exactly what to paste.

Can an AI agent delete or change things in Bitwarden?

Only if its key allows it, and only with an explicit confirmation. 4 Bitwarden actions are destructive, including remove member, delete group and revoke member. 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 Bitwarden API limit?

actionlake paces every call to the limits in the Bitwarden service file: 120 calls a minute per connection. Repeated reads are answered from cache (11 Bitwarden actions can be), which never reaches Bitwarden.

What does a Bitwarden action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (28 Bitwarden actions page). Cache hits, searches, dry runs and calls Bitwarden 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 Bitwarden API does it cover?

The Bitwarden Public API (organization administration) API public at api.bitwarden.com/public by default, or the base URL set when you connect. It is built from Bitwarden's documentation as read on 20 September 2026. 28 actions in 1 area, each one in the signed service file (version 1.0.0).

Does actionlake keep my Bitwarden 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 Bitwarden 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.
