Connectors · Work & projects
OpenProject MCP server for AI agents.
actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to OpenProject and the rest of your systems. It gives your agent 298 OpenProject actions (194 reads, 76 writes and 28 that wait for a confirmation) and holds the OpenProject credential itself, so the agent never does. It paces OpenProject'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 OpenProject 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 OpenProject.
Username and secret. 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,
checkvalidates the call and prices it, for free.do { action: "openproject.work_packages.list_work_packages" }# list work packages · read · 1 upstream callcheck { action: "openproject.work_packages.create_work_package", input: { … } }# free: inputs, permissions, cost and confirmations, nothing sent

Top actions
The OpenProject API, shaped for agents.
The ids your agent types, what each does, and the one name it shares with other systems. 57 of OpenProject's 57 action names are shared with at least one other connector, so an agent learns them once.

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 OpenProject MCP server, answered.
Is there an OpenProject MCP server for Claude?
Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 298 OpenProject actions across work packages, meetings, queries and projects, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by OpenProject.
What do I need to connect OpenProject?
OpenProject API token (My account > Access tokens > API > Generate). Plus your host. The free call account { op: "connections.requirements", service: "openproject" } lists exactly what to paste.
Can an AI agent delete or change things in OpenProject?
Only if its key allows it, and only with an explicit confirmation. 28 OpenProject actions are destructive, including delete Work Package, delete Project and delete user. 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 OpenProject API limit?
actionlake paces every call to the limits in the OpenProject service file: 10 calls a second per connection. Repeated reads are answered from cache (167 OpenProject actions can be), which never reaches OpenProject.
What does an OpenProject action cost?
One upstream call, the only unit actionlake bills. A list that pages bills one call per page (298 OpenProject actions page). Cache hits, searches, dry runs and calls OpenProject 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 OpenProject API does it cover?
The OpenProject API v3 (OpenAPI 3.1.2) at your OpenProject instance's API base URL, which you enter when connecting. It is built from OpenProject's documentation as read on 23 October 2026. 298 actions in 54 areas, each one in the signed service file (version 1.0.0).
Does actionlake keep my OpenProject 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 OpenProject 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.
