Skip the install. Get this working in under 2 minutes.
Start a free trial on cloud.anythingmcp.com, add the OpenProject in one click, then point your AI client (Claude, ChatGPT, Copilot or Cursor) at the generated MCP endpoint. No Docker, no git clone, zero engineering experience required.
AnythingMCP's plugin in ChatGPT's directory answers questions from your company databases on AnythingMCP Cloud (PostgreSQL, MySQL, SQL Server, Oracle, SAP HANA, SQLite, MongoDB, read-only): open the listing (opens in a new tab) and click Install plugin. Every other connector is added to ChatGPT as a custom MCP server with your AnythingMCP MCP URL.

OpenProject + ChatGPT
OpenProject: projects, work packages with their activities, versions, time entries, users and statuses, queried with OpenProject's filter grammar. API v3, Basic auth with the literal username apikey.
Prerequisites
See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:
OPENPROJECT_URL, OPENPROJECT_API_KEY
Step 1 — Get credentials
Getting a key
- In OpenProject open My Account → Access tokens and generate an API token.
- Set
OPENPROJECT_URLto your instance root (no trailing slash) andOPENPROJECT_API_KEYto the token.
The Basic-auth username is the literal string apikey. Not your login name — the word apikey, with the token as the password. This adapter does it for you, and it is the first thing to check when a token you know is valid returns 401.
Permissions follow the user. The token inherits its owner's project memberships and roles. A project the user is not a member of is simply absent from the results, not an error.
…(continued in the in-app connector instructions)
Step 2 — Install the adapter
curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d
Step 3 — Add the connector in ChatGPT
Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (
https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide showsYOUR_SERVER_ID.
ChatGPT adds MCP servers as plugins on its Plugins page, on the web and on paid plans. Developer mode is no longer needed. In a Business workspace only admins and owners can add one; in Enterprise and Edu an admin can grant the Create plugins with MCPs permission.
- Go to chatgpt.com/plugins, click Add, then Add custom MCP server.
- Enter a name, e.g. Name:
OpenProject. - Under Connection, enter the Server URL
https://cloud.anythingmcp.com/mcp/YOUR_SERVER_IDand keep Authentication on OAuth. - Select I understand and want to continue, then Create as a plugin. When ChatGPT asks, sign in to AnythingMCP and allow access.
- Install the new plugin from your personal plugins, then type @ in a chat and pick it.
Available tools
| Tool | What it does |
|---|---|
openproject_get_me | Read the user the API token belongs to, with their name, e-mail, language and admin flag |
openproject_list_projects | List projects with their identifier, name, status, description and active flag |
openproject_list_work_packages | List work packages — tasks, bugs, features, milestones — across all projects, with their type, status, assignee, dates and priority |
openproject_list_project_work_packages | List the work packages inside one project — the usual scope for 'what is open on this project' and much cheaper than filtering globally |
openproject_get_work_package | Read one work package in full: description, type, status, assignee, dates, estimated and spent time, and its custom fields |
openproject_list_work_package_activities | Read the activity stream of one work package: every comment and field change in order, with author and timestamp |
openproject_list_time_entries | List logged time entries with their user, work package, date, hours and comment — the raw data behind any effort report |
openproject_list_versions | List versions (releases and sprints) with their name, status, due date and the project they belong to |
openproject_list_users | List users with their name, e-mail, login and status, to resolve who a work package is assigned to |
openproject_list_statuses | List the work-package statuses this instance defines, with their id, name and whether each counts as closed |
FAQ
Does the free ChatGPT plan work with custom MCP servers? OpenAI documents custom MCP servers for paid plans only; the Free plan is not on its list.
